Purpose of this guide

This regulatory guide sets out ARPANSA’s expectations for the disposal of: 

Explanation of terms

In this guide the generic meaning of ‘disposal’ is used. It includes the transfer of controlled apparatus and controlled material (collectively referred to as sources) to another ARPANSA licence holder or to a person/organisation outside of ARPANSA’s jurisdiction.

The term ‘source’ is used to collectively mean controlled apparatus and controlled material.   

A ’security enhanced source’ means a radioactive source or aggregation of sources assigned the Category 1, 2 or 3 when using the methodology set out in Schedule B of Code of Practice for the Security of Radioactive Sources (RPS 11).

Introduction

Section 65 of the Regulations provides 4 disposal options:

  1. The licence holder may dispose of controlled material or controlled apparatus with prior approval from the CEO
  2. The licence holder may without approval of the CEO transfer the controlled apparatus or controlled material to another licence holder under certain conditions
  3. The licence holder may without approval of the CEO dispose of the controlled apparatus by returning certain controlled apparatus to the supplier of the controlled apparatus in certain circumstances  
  4. The licence holder may without approval of the CEO dispose of certain controlled apparatus by rendering the controlled apparatus permanently inoperable as a controlled apparatus in certain circumstances.

Under option 2, prior approval is not required to transfer a source to another ARPANSA licence holder provided:

  • both entities hold an appropriate licence issued by the CEO of ARPANSA,
  • the apparatus does not contain a security enhanced source, and
  • the licence holder disposing of the apparatus tells the CEO about the transfer within 7 days.

A Source Transfer Notice must be submitted within 7 days of the transfer.

Where a licence holder routinely disposes of sources as part of routine operations the CEO of ARPANSA can make a special arrangement in the licence under subsection 65(5) of the Regulations so there is no need to seek prior approval to dispose of each source.  

Note: Temporary transfer of sources to a service agent for repair or maintenance is not a disposal as ownership is retained by the licence holder.  In such cases the licence holder must ensure that the service agent has appropriate training in radiation safety and training with respect to such activities (as required by all licences). 

Disposal of controlled apparatus

As defined in section 13 of the Act, controlled apparatus means any of the following:

  1. An apparatus that produces ionising radiation when energised or that would, if assembled or repaired, be capable of producing ionising radiation when energised
  2. An apparatus that produces ionising radiation because it contains radioactive material
  3. An apparatus prescribed by the regulations that produces harmful non-ionising radiation when energised.

Disposal of controlled apparatus often includes destruction or dismantling.

Disposal of controlled apparatus requires prior approval from the CEO of ARPANSA unless the licence makes other arrangements under subsection 65(5) of the Regulations OR the disposal meets the conditions described in paragraphs 65(1)(c) & (d) for certain controlled apparatus.  This allows Group 1 controlled apparatus to be returned to the supplier or rendered permanently inoperable without prior approval provided it does not contain controlled material.

To satisfy the CEO of ARPANSA of the ‘destruction’ of a controlled apparatus it must be rendered inoperable in such a way that only expert knowledge and the use of specialised components could potentially restore its function. 

In most cases, removal of a critical component(s) and severing the power cables will render the apparatus inoperable. For example: 

  • In the case of x-ray apparatus, eliminating the vacuum inside the x-ray tube by breaking the glass envelope and severing the high-tension cables will effectively destroy the apparatus.  
  • In the case of lasers removing the power supply, critical optical components or the amplifying medium will render the apparatus inoperable. 

In all cases, the licence holder must take into account the presence of other hazardous materials, for example: beryllium, mercury, cadmium, etc. The licence holder should seek guidance from their local environmental agency on disposal requirements for such material or investigate possible recycling options.  

Once destroyed, the apparatus ceases to meet the definition of a controlled apparatus and is therefore no longer subject to regulatory control. Individual dismantled parts are not deemed to be controlled apparatus.

If apparatus is to be disposed of because it has ceased to function, a critical component should still be removed so that repair is not possible.

In the case of apparatus containing radioactive material, removal of the material means the apparatus is no longer ‘controlled’.  However, depending on the activity of the material removed, it may still be subject to regulatory control and need to be authorised by a licence. 

Where disposal to landfill is proposed, the licence holder should ensure that the removed critical components are discarded separately to the rest of the apparatus unless they are to be retained as spare parts. This is to prevent any chance of them being recombined or repaired. Recycling should be considered where possible.

Transfer a source out of ARPANSA's jurisdiction

Sources are often sold, leased, hired, or given away to a person or organisation in another jurisdiction - such action is regarded as a ‘transfer’. This includes the return of controlled material to the original manufacturer or supplier in another jurisdiction or in some cases overseas.  

In the majority of cases prior approval is required for a source to leave ARPANSA’s jurisdiction.  However, paragraph 65(1)(c) of the Regulations provides for certain Group 1 controlled apparatus to be returned to the supplier without prior approval as noted above.    

Particular attention is required when proposing to dispose of multiple low activity sources in a single shipment. The activity of all sources must be aggregated (using the method in Schedule B of RPS 11) to determine if additional security arrangements apply.

 

Additional requirements for security enhanced sources:

Licence holders must be aware of the additional security arrangements for security enhanced sources, in particular the requirement for an endorsed transport security plan – see RPS 11 (para 5.3)

It is important that receipt of the source is confirmed at its final destination particularly if overseas.   

If the final destination is outside Australia the licence holder must ensure that the required documentation is completed noting that an ARPANSA Export Permit is required for the export of high activity sources. For the definition of a high activity source and information about how to apply for an export permit please see Export permits | ARPANSA.

Transfer a security enhanced source to another ARPANSA licence holder

Under RPS 11 (2.1.11) the transfer of a security enhanced source must have prior approval from the CEO even if the transfer is between ARPANSA licence holders.

Licence holders must comply with the additional security requirements, in particular the requirement for an endorsed transport security plan as per para 5.3 of RPS 11.  

How to apply for approval to dispose of a source

Licence holders seeking approval to dispose of a source should use the Request for approval to dispose of a source. Completed forms should be sent to licenceadmin@arpansa.gov.au.

Licence holders must comply with their obligations under the following codes:

Follow up actions

Maintaining an accurate inventory

Following physical disposal, the status of the source in the source inventory workbook (SIW) should be changed to ‘Transferred’ or ‘Disposed’ and the date recorded.   

Reporting compliance 

Compliance reports submitted by licence holders must include summary information about disposals that have occurred during the reporting period. This includes disposals that did not require prior approval to ensure that databases are updated.    

 

   

 

Regulatory Guide - Reporting compliance (ARPANSA-GDE-1741)

Introduction

Subparagraph 7(d)(i) of the Australian Radiation Protection and Nuclear Safety Regulations 2018 (the Regulations) requires the CEO to make guidelines about how licence holders will report their compliance with the Australian Radiation Protection and Nuclear Safety Act 1998 (the Act), the Regulations and licence conditions. This document fulfils that requirement and provides information on when, how and what licence holders must report. 

ARPANSA applies a graded approach to compliance reporting. The frequency of reporting is aligned with the regulatory priority of the source or facility. The regulatory priority is risk-based.

When to report

Licence holders are required to report quarterly, biannually (i.e. 6-monthly) or annually. The frequency of reporting is specified in Schedule 2 of the licence. 

For licence holders who report quarterly, a report must be provided to the CEO of ARPANSA in an approved form within 28 days of the end of each quarter, i.e. by 28 January, April, July and October, or within such other period as determined by the CEO. 

For licence holders who report 6-monthly, a report must be provided to the CEO in an approved form by 28 January and 28 July each year, or within such other period as determined by the CEO. 

For licence holders who report annually, a report must be provided to the CEO in an approved form within 28 days of the end of the financial year, i.e. by 28 July each year, or within such other period as determined by the CEO. 

To assist licence holders in timely reporting, an email reminder is sent to licence holders two weeks prior to the end of the reporting period. 

How to report

Licence holders must use the Regulatory Administration Database (RAD) portal to submit the report, unless there are other agreed arrangements in place. The submission must use the form within RAD, or source inventory templates [1] are available on request.

Reports should be submitted by a person authorised to provide such information on behalf of the licence holder, such as a Radiation Safety Officer or the primary licence contact. Receipt of the report will be acknowledged by ARPANSA.

Please note that any documentation classified ‘Protected’ or above should not be transmitted via RAD or to a generic email address, please contact ARPANSA for further information.

What to report    

The licence holder should address all matters in the report template. Guidance on the information required is provided below. 

1. Notifiable incidents (section 58 of the Regulations)    

Under section 58 of the Regulations, the licence holder must tell the CEO about a notifiable incident within 24 hours of it happening and give the CEO a written report about the incident within 14 days of it happening. 

Guidance on what constitutes a notifiable incident for the purposes of section 58 is provided in Regulatory Guide: Radiation Incidents

The licence holder should also provide a summary of any notifiable incidents that occurred during the reporting period.

2. Other incidents

Except as otherwise required by a special licence condition, the licence holder should report any other incident during the reporting period that had the potential to affect safety, but which was not notifiable under section 58 of the Regulations.

This may include any unintended event, including operating error, equipment failure, initiating event, accident precursor, near miss or other mishap, or any unauthorised act whether or not it was malicious, the consequences or potential consequences of which are not negligible.

For example:

  • Loss of a Group 1 sealed source
  • Minor contamination of laboratory clothing or work area
  • Breach of operating limits and conditions
  • Deliberate exposure of a personal monitoring device
  • Incorrect settings on a safety system
  • Sticking shutter mechanism on a radiation gauge
  • Laser incident where there is the potential for injury

3. Personal monitoring 

Part 6 Division 2 of the Regulations sets out the practices to be followed by licence holders with respect to dose limits (ionising radiation) or exposure limits (non-ionising radiation). 

Any event where an individual is exposed to radiation exceeding a dose limit / exposure limit is regarded as a notifiable incident and must be reported under section 58.

Other unusual doses or exposures that required investigation or corrective action during the reporting period should be reported. 

4. Acquisition of a source 

The licence holder should provide a summary of sources acquired during the reporting period. Import permit numbers should be quoted where relevant.

When changes to the source inventory occur these must be updated in RAD. Updates can be made via the web portal at any time. Where required ARPANSA can provide the latest version of the source inventory to be updated by the licence holder and returned. 

Before acquiring a source the licence holder should consider which of the following regulatory actions is required: 

  • New licence application
  • Prior approval under section 63 of the Regulations
  • Reporting a change to the source inventory under section 64 of the Regulations

For further guidance on the regulatory implications of making changes to the source inventory including acquiring, using, transferring or disposing of sources, see Appendix A.

5. Disposal of a source (section 65 of the Regulations) 

The licence holder should provide a summary of any disposals made during the reporting period. 

 Licence holders should refer to Regulatory Guide: Disposal of controlled apparatus and controlled material. Disposals may require prior approval as well as updating the inventory that the disposal has taken place.

For further guidance on the regulatory implications of making changes to the source inventory including acquiring, transferring, disposing, or using new sources, see Appendix A.

6. Transfer of a source (section 65 of the Regulations)

The licence holder should provide a summary of any source transfers made during the reporting period.

Licence holders should refer to Regulatory Guide: Disposal of controlled apparatus and controlled material.

Transfer provisions also apply to infrequent sales, hires, loans, gifts, or donations within Commonwealth jurisdiction. Licence holders should notify the CEO about the transfer of a source using RAD, or where appropriate the Transfer Notice Form

Transfers under subsection 65(3) must generally be reported within 7 days, unless the source is in security category 1, 2 or 3[2] in which case prior approval from the CEO of ARPANSA must be obtained before the transfer regardless of the jurisdiction to which it is being transferred. 

Under subsection 65(5) of the Regulations the licence may make other arrangements with regard to source transfers such as where regular source transactions are part of routine operation and seeking prior approval for every transfer would be impractical. An example of such an arrangement is where there are regular sales of controlled material or controlled apparatus. Any alternative reporting arrangements will be specified in the licence.

Transfer of a controlled facility requires prior approval from the CEO under subsection 65(4) of the Regulations.

For further guidance on the regulatory implications of making changes to the source inventory including acquiring, using, transferring or disposing of sources, see Appendix A.

7. Corrective action arising from an inspection 

The licence holder should report progress on any corrective actions arising from an inspection in accordance with the reporting requirements specified in the inspection report or covering letter. 

8. Changes with significant implications for safety (section 63 of the Regulations)

The licence holder should provide a summary of any approvals sought and received under section 63 during the reporting period. 

For guidance on how to categorise a change, licence holders should refer to Regulatory Guide: When to seek approval to make a change with significant implications for safety

9. Changes unlikely to have significant implications for safety (section 64 of the Regulations)

Under section 64, licence holders must report any change that is unlikely to have significant implications for safety at least once every 3 months. Licence holders reporting quarterly will include this information in their quarterly report. However, licence holders reporting biannually (6-monthly) or annually must inform ARPANSA of the change within 3 months.

10. Review of plans and arrangements (section 61 of the Regulations)

Licence holders are required to review their plans and arrangements (and their safety analysis reports where applicable) at least once every 3 years and keep records of the review and any changes made. 

When conducting the review, licence holders should refer to the Regulatory Guide: Plans and Arrangements for Managing Safety.

11. Compliance with special licence conditions

The licence holder should report progress against any special licence conditions. Any such conditions will be removed when compliance has been adequately demonstrated. 

12. Breaches of licence conditions (section 57 of the Regulations) 

ARPANSA encourages licence holders to find and fix their own non-compliance. Such behaviour reflects a healthy and robust safety culture. Whenever a potential breach is encountered, the licence holder has a responsibility under section 57 to investigate and rectify the breach including any consequences of the breach as soon as reasonably practicable. 

The licence holder must tell the CEO as soon as reasonably practicable if a breach of a licence condition is identified. The quarterly/biannual/annual report must also include a summary of any breach reported during the reporting period.

Common breaches relate to: 

Section 57A: A licence holder not taking all reasonably practicable steps to prevent and minimise human errors and organisational failures.

Section 60: A licence holder not taking all reasonably practicable steps to comply with their plans and arrangements.

Section 61: A licence holder not reviewing and updating plans and arrangements (and safety analysis reports where applicable) at least once every 3 years/not keeping records of the review.

Section 63: A licence holder not seeking the CEO’s prior approval to make certain changes that have significant implications for safety.

Section 65: A licence holder not seeking prior approval from the CEO or telling the CEO about movement of a source or facility, in particular failure to obtain prior approval before disposing of a source.

In many cases, the licence holder will be expected to perform a root cause analysis to fully investigate the potential breach. An investigation that involves a root cause analysis (to prevent recurrence) may take considerable time. 

Appendix A: Regulatory implications of changes to the source inventory

Under section 62 of the Regulations the licence holder must keep an accurate inventory of sources it deals with. The approved form for maintaining this information is the RAD Portal, or using a source inventory spreadsheet (available on request). 

The licence holder must consider the regulatory implications of making any change to the source inventory after the licence is issued. 

Licence holders intending to acquire, relocate, transfer, dispose of, or modify a source or facility should refer to sections 63-65 of the Regulations and licence conditions to identify what action is required under the ARPANSA regulatory framework. It is particularly important to identify whether a proposed change requires the prior approval of the CEO of ARPANSA or, in some cases, whether a new licence application is necessary. 

Licence holders should also refer to Regulatory Guide: When to seek approval to make a change with significant implications for safety to determine whether a proposed change requires prior approval. 

A1. Adding to the source inventory 

If the licence holder intends to acquire a kind of source that is not authorised by the existing licence (or any other source licence that the licence holder might have[3]) then a new application must be submitted with the appropriate fee and the licence must be amended and re-issued by ARPANSA before taking possession of the source. Failure to do so may result in a breach of subsection 31(1) of the Act. 

Acquiring additional sources of a kind that is already authorised by the licence does not require prior approval but this is a change[4] for the purpose of section 64 of the Regulations and should be reported within 3 months or by the next quarterly report. Updates to the inventory can be made in the RAD Portal at any time.

Occasionally licence holders may discover sources in their possession that are not listed in their source inventory. These are often ‘legacy’ sources or sometimes non-ionising apparatus such as a Class 3B laser or UV source.

If a kind of source not covered by the licence is identified it may be necessary for the licence holder to apply for an authorisation to continue to possess, have control of, or use it. Advice should be sought from ARPANSA if there is any doubt about the status of a legacy source. 

A2. Removing a source from the SIW

Under section 65 of the Regulations a licence holder must have prior approval from the CEO of ARPANSA to:

(i) dispose[5] of a controlled apparatus or controlled material (source) 

(ii) transfer a source to another jurisdiction (outside of the Commonwealth)

However some exceptions apply; licence holders should refer to Regulatory Guide: Disposal of controlled apparatus and controlled material

Transfers within the commonwealth, under subsection 65(3), must generally be reported within 7 days unless the source is in security category 1, 2 or 3 in which case the transfer must have the prior approval of the CEO of ARPANSA. This prior approval requirement comes from Radiation Protection Series No. 11 - Code of Practice for the Security of Radioactive Sources compliance with which is a statutory licence condition under section 59 of the Regulations. Failure to comply with sections 59 or 65 of the Regulations may result in the licence holder being found in breach of subsection 31(2) of the Act. Transfer can be applied for or notified via the RAD Portal.

Following transfer or disposal of a source, its status should be changed in the source inventory in RAD accordingly. 

When an item no longer meets the definition of a controlled apparatus or controlled material the licence holder should change its status in the source inventory in RAD, and provide further details where relevant, for example: the source has decayed below the exemption limit or changes to the apparatus mean that it no longer meets the definition of a controlled apparatus. 

A3. Licence holders with multiple divisions and/or multiple sites 

Some licence holders have a number of divisions at one location or occupy premises spread over multiple sites. Each division may have a separate source licence and separate source inventory. The licence holder may also have one or more facility licences.

If a licence holder wants to undertake a new dealing in a particular division, the licence holder must determine whether section 63 of the Regulations applies or whether a new application is required. If the new dealing is not authorised by any existing source licence held by that organisation then a licence application is required. If the new dealing is authorised by an existing source licence, held elsewhere in the organisation, then section 63 applies.

If a licence holder wants to relocate a source from one division to another, from one site to another, or from one licence to another, the licence holder must determine whether a new licence application is required or whether section 63 or 64 of the Regulations applies under an existing licence. For example: 

a) Relocation of a source within the same division at the same site 

Section 64 of the Regulations applies; the licence holder must report the change to the source inventory within 3 months or in the next quarterly report. These updates can be made at any time via the RAD Portal.

b) Relocation of a source within the same division but at a different site

Section 64 of the Regulations applies if the source is to be used for the same as that described in the application and plans and arrangements, otherwise section 63 applies. These updates or applications can be made at any time via the RAD Portal.

c) Relocation of a source to a different division at the same site 

Section 64 of the Regulations applies if the division receiving the source is authorised for the source type/dealing, and provided there are no implications for safety, otherwise section 63 applies (see Scenario 3). Note that subsection 65(3) of the Regulations also applies as the transfer of a source from one licence to another must be reported to ARPANSA within 7 days, except for security-enhanced sources that require prior approval. These updates or applications can be made at any time via the RAD Portal.

d) Relocation of a source to a different division at a different site

As for (c) above.

e) Transfer of a source from a facility licence to a source licence

A licence application is required unless the source type/dealing is authorised by an existing source licence. If authorised, then section 64 of the Regulations applies. Subsection 65(3) also applies - see (c) above. These updates or applications can be made at any time via the RAD Portal.

f) Transfer of a source from a source licence to a facility licence 

If the facility licence already authorises dealing with this kind of source then section 64 of the Regulations applies. If not, then section 63 applies and approval from the CEO of ARPANSA must be obtained prior to the transfer. Note that dealing with the source must be included in the safety assessment report for the facility. These updates or applications can be made at any time via the RAD Portal.

Further guidance is provided in the scenarios and examples below. If there is any uncertainty about the regulatory implications of a proposed change to the source inventory, please contact ARPANSA.

 Scenario 1: A licence holder wants to acquire a source of a type and for a dealing already authorised by the licence

In this situation a licence application is not required and the existing licence does not need to be amended. This is because the licence holder’s plans and arrangements for managing that type of source have already been assessed as satisfactory for the particular dealing. The change is regarded as unlikely to have significant implications for safety and is therefore subject to section 64 of the Regulations.  These updates can be made at any time via the RAD Portal.

Example 1: A licence holder is authorised to deal with a fully enclosed X-ray analysis unit (Group 1 Item 13). The licence holder wants to acquire another fully enclosed X-ray analysis unit.No amendment to the licence is necessary. Section 64 of the Regulations applies: acquisition of the source must be reported within 3 months by updating the inventory. For most licence holders this will be by the next quarterly report. 

 Scenario 2: A licence holder wants to acquire a source of a type not authorised by the licence

In most cases, a licence amendment application will be required. 

Example 2: A licence holder is authorised to deal with a fully enclosed X-ray analysis unit (Group 1 Item 13). The licence holder wants to acquire a partially enclosed X-ray analysis unit (Group 2 Item 11).The licence holder must apply for a licence amendment to add Group 2 Item 11 before the apparatus is acquired. Once acquired, the licence holder must update their inventory.

 Scenario 3: A licence holder wants to relocate a source from the location specified in the source inventory

This is a proposed change to details provided in the licence application (or subsequently approved) and therefore a change relevant to either section 63 or 64 of the Regulations. The licence holder must decide which applies, that is, whether the relocation is likely to have significant implications for safety. 

Prior to moving a source, the licence holder must consider such things as shielding, storage, security, and transport. If there are significant implications for safety in the process of relocation or at the new location, then prior approval is required under section 63. If there are unlikely to be any significant implications for safety, prior approval is not required but relocation of the source must be reported under section 64 within 3 months or in the next quarterly report. 

Example 3: A fixed industrial X‑ray unit located in Building A is to be relocated to Building BThis may have a significant effect on safety in terms of protective shielding, interlocks, warning lights, etc. Such a change would require the prior approval of the CEO under section 63 of the Regulations.
Example 4: The source inventory shows an unsealed source is being used in Laboratory CIf the licence holder relocates this source to Laboratory D with the same policies and procedures and with equivalent or better storage and handling, then the change is unlikely to have significant implications for safety. Such a change would fall under section 64 of the Regulations with no prior approval required. The change of location should be reported within 3 months or in the next quarterly report. The source inventory will also need to be updated.

 Scenario 4: A licence holder wishes to deal with a source that belongs to another organisation

There are certain situations where a licence holder may wish to use a source owned by another organisation. For example, a source may be leased, hired or borrowed, or a controlled person may be required to use another organisation’s source at that organisation’s premises. 

Under section 13 of the Act, the definition of ‘deal with’ includes possession or having control of. Therefore, use of a source belonging to another organisation may only be undertaken if authorised by a source licence. In such circumstances the licence holder must consider whether the existing authorisation covers the proposed activity or whether an amendment to the licence or further licence application is required. 

Example 5: Licence holder (Y) wants to lend a sealed source to another Commonwealth licence holder (Z) for a particular project

Licence holder Z must be authorised for the proposed dealing. The transfer of possession is covered by paragraph 65(2)(b) of the Regulations and must be reported to the CEO within 7 days. In this case, the source inventory of licence holder Y should be amended to indicate that the source is temporarily on loan. The source inventory of licence holder Z should also be amended to include the source until it is returned. In any case the temporary transfer should also be reported in accordance with section 64. Similarly, the return of the source should also be reported and the source inventories amended as appropriate.

Note: Changes to the source inventory are only relevant if the loan is for an extended period, i.e. more than 3 months. Short-term loans should still be reported in the compliance report to ARPANSA.

Example 6: A source licence authorises the licence holder to deal with baggage X-ray units. The licence holder leases an additional baggage X-ray unit from an equipment supplierThe licence holder must report the additional source by updating the inventory within 3 months or by the next quarterly report. Eventual return of the sources to an organisation outside the Commonwealth’s jurisdiction requires prior approval.
Example 7: A source licence authorises dealings with a fully enclosed analytical X-ray unit. In a collaborative venture with a university, it is proposed that a controlled person covered under the source licence will use a fully enclosed analytical X-ray unit owned by the university at the university’s premises. This dealing is authorised under the source licence. The CEO should be advised of this dealing under section 64 of the Regulations. The conditions attached to the licence with respect to this kind of controlled apparatus are still applicable. Where direct compliance with these conditions is outside the control of the licence holder (as in the case of equipment maintenance) it is the responsibility of the licence holder to be satisfied that the conditions have been met and to provide supporting evidence to ARPANSA if required. For example, the licence holder may be required to provide ARPANSA with the licensing or registration information from the relevant State/Territory regulatory authority.

[4] The definition of a ‘change’ for the purposes of sections 63 and 64 of the Regulations is: a change to the details described in the application for the licence; or a modification of the source or facility.

[5] Disposal of controlled apparatus for the purpose of subsection 65(1) of the Regulations includes destruction.
 

Regulatory Guide - Radiation incidents (ARPANSA-GDE-1749)

This Regulatory Guide informs licence holders on the actions to be taken if a radiation incident occurs, when ARPANSA must be notified, and how to make such a notification. 

Associated forms

Introduction

Sections 57A & 58 of the Australian Radiation Protection and Nuclear Safety Regulations 2018 (the Regulations) places obligations on licence holders to prevent, control and minimise incidents; in doing so they must take into account human and organisational factors. 

Incidents that must be reported to ARPANSA are defined, as are the actions that must be taken by the licence holder if an incident occurs. 

An incident is:

  1. any unintended event, including an operating error, equipment failure, initiating event, accident precursor, near miss or other mishap; or
  2. any unauthorised act, whether or not malicious

the consequences or potential consequences of which are not negligible from the point of view of protection and safety.

This includes events where controlled apparatus or material had the potential to result in an exposure to radiation to any person or the environment, outside the range of that normally expected for a particular practice.

Notifiable incidents

A notifiable incident requires immediate action and must be reported to ARPANSA within 24 hours, and a written report must be provided to ARPANSA within 14 days.

notifiable incident means any of the following:

  • an incident that exposes a person to a dose of ionising radiation that exceeds an effective dose limit mentioned in section 77 or an equivalent dose limit mentioned in section 79 of the Regulations
  • an incident involving a diagnostic or interventional medical procedure resulting in an observable acute radiation effect
  • an incident involving exposure to non-ionising radiation from controlled apparatus that exceeds the non-ionising radiation exposure limits or results in noticeable eye or skin damage
  • a theft or loss of controlled material or controlled apparatus, other than controlled material or controlled apparatus in Group 1
  • an incident involving the release of controlled material if the result of the activity value division steps* for the controlled material is greater than 104
  • an incident involving transport of a package of controlled material if the result of the activity value division steps for the controlled material is greater than 104 and the package is damaged in such a way that safety provisions are degraded.

* activity value division steps for sources or controlled materials are the following:

(a)  first, divide the activity of each nuclide in the sources or controlled materials by the activity value set out in Part 1 of Schedule 1 of the Regulations for the nuclide;
(b)  secondly, if there is more than one nuclide in the sources or controlled materials, total the result of paragraph (a) for each nuclide.

Note: Section 5 of the Regulations affects how the activity of a parent nuclide mentioned in Part 2 of Schedule 1 (or marked a in Part 1 of Schedule 1) is worked out, by providing for inclusion of the activity of certain progeny nuclides that are included in secular equilibrium with the parent nuclide.

Worked example

Suppose there are two vials in a laboratory cupboard, one containing 10 MBq of Co-60 and the other containing 100 MBq of Cs-137.  Assume a fire destroys the cupboard and the vials and all activity is released. Is this a notifiable incident?

Schedule 1 Part 1 of the Regulations gives activity values of 105 Bq and 10Bq for Co­‑60 and Cs-137 respectively.  If all activity is released, the result would be:

(107/105) + (108/104) =102 + 104 which is > 104   Hence this is a notifiable incident

What to do if a notifiable incident occurs

Preserve the site

Priority should be given to controlling and mitigating the consequences of the incident. However, as far as possible, it is essential that the integrity of the incident site is preserved to allow an analysis of the conditions at the site and a thorough investigation as to the cause(s) of the incident.

Special attention should be paid to the importance of securing the site or the facility to prevent any destruction or cross-contamination of the physical information as well as to protect responding personnel and others.  

See Regulatory Guide: Radiation incident site preservation for further information.

Notify ARPANSA 

Within 24 hours of a notifiable incident occurring the licence holder must tell ARPANSA.

Investigate and provide a written report within 14 days

When investigating a radiation incident the following questions should be considered:

  • What happened?
  • How did it happen?
  • Why did it happen?  
    As described in the holistic safety guide, consider the whole system of technical (e.g. human-machine interface design), human (e.g. cognitive demands, fatigue), and organisational (e.g. leadership, safety culture) factors. Also consider the interactions between these factors (e.g. how individuals use technology to communicate safety-critical information across multi-disciplinary teams).
  • Was the severity of the incident and its likelihood of occurrence accurately reflected in the risk assessment? 

These questions will help identify the causes and contributing factors with the ultimate aim to improve safety.

A written report must be provided to ARPANSA that contains an account of the incident and its consequences including where possible:

  • an estimate of the dose received by any person
  • an assessment of any impact on the environment
  • an assessment of technical, human and organisational factors that contributed to the incident
  • any corrective action taken as a result of the incident
  • actions taken to prevent the recurrence of similar events
  • the impact on safety
  • identified security implications.

NOTE: If the report is not final it should still be submitted within 14 days and be clearly marked as preliminary. The final version must be provided as soon as practicable and within a reasonable timeframe.

Review of plans and arrangements

Following a notifiable incident the licence holder must review and update plans and arrangements for managing safety. This review should include:

  • the design process for equipment, or processes relevant to the incident
  • the performance of the risk assessment
  • any review or safety approval system that authorised an activity which led to the incident.

The licence holder must complete the review within 6 months of the incident happening and must provide the CEO with a written summary of the outcome of actions resulting from the review within 7 months of the incident happening. The CEO may extend these periods on request.

Reporting other incidents

Any other incidents - such as operating errors, equipment failures, initiating events, accident precursors, near misses or other mishaps - that are not notifiable within 24 hours should be reported to ARPANSA as part of routine compliance reporting. This can be completed via the RAD Portal at any time. 

This allows ARPANSA to follow-up as necessary especially where there may be lessons for other licence holders or the industry more broadly. 

Disclosure of information

For incidents of the type mentioned in the National Directory for Radiation Protection (2nd Edition, 2021) (NDRP) de-identified information will be included in the Australian Radiation Incident Register (ARIR), Australia's national database of incidents and events resulting from activities involving radiation.

ARPANSA may also submit relevant information to international registers such as that maintained by the IAEA for events on the International Nuclear and Radiological Event Scale (INES).

ARPANSA may also share information with other regulatory agencies including safety and state and territory radiation protection regulatory bodies where this is required.
