Our Agency
Protecting people and the environment from the harmful effects of radiation


The Australian Radiation Protection and Nuclear Safety Agency (ARPANSA) operates under the Australian Radiation Protection and Nuclear Safety Act 1998 (the ARPANS Act). The ARPANS Act allows the CEO to engage staff to assist in the performance of the Agency's statutory functions for the purposes of the Public Service Act 1999. ARPANSA is a prescribed Agency under the Financial Management and Accountability Act 1997 within the Government's Health portfolio.

Responsible ministers and portfolio

During this financial year, the Parliamentary Secretary to the Minister for Health and Ageing had ministerial responsibility for ARPANSA.

Funding basis

ARPANSA is funded through appropriations received directly as part of the Federal Budget.

ARPANSA's own sourced income derives from: the sale of scientific services such as the Personal Radiation Monitoring Service; Comprehensive Nuclear-Test-Ban Treaty Organization contracts to build, operate and maintain monitoring stations; and licence application fees and annual charges associated with ARPANSA's regulatory activities.

Our outcome

Protection of people and the environment through radiation protection and nuclear safety research, policy, advice, codes, standards, services and regulation.

Our people

As at 30 June 2013 ARPANSA employed a total of 138 ongoing and 11 non-ongoing staff. Our people are specialists in nuclear and medical physics, radiation sciences, chemistry, biological sciences, security and emergency preparedness as well as communications, government policy, law, finance and human resources.

'Protection of the public and environment from radiation requires a risk-informed approach which takes account of both safety and security. ARPANSA does this by providing appropriate and effective information on exposure to all sources of ionising and non-ionising radiation; interacting with and informing the Australian community about risks associated with exposure to radiation; and, promoting implementation of radiation safety measures that optimise protection of the public and the environment'
Where we work

ARPANSA's staff are spread across three sites: Miranda in New South Wales, Yallambie in Victoria and Barton in the Australian Capital Territory.

Our mission

To assure the protection of people and the environment from the harmful effects of radiation.

Our vision

In protecting people and the environment from the harmful effects of radiation, ARPANSA ensures that:

  • radiation safety is appropriately considered in societal decision-making which rests on sound science, with radiation safety given appropriate weight, guiding the use of precaution as necessary.
  • radiation safety is consistently applied, across jurisdictions and activities, in a manner that is commensurate with risk.
  • radiation safety in Australia is current international best practice.
  • the Agency takes a leading role in the enhancement of the international radiation safety framework, promoting and implementing best practice nationally, in the region and internationally.
Key areas

ARPANSA delivers outcomes for Australian society in a set of Key Areas and each Key Area is informed by strategies and associated activities which are defined annually and form the basis for the Portfolio Budget Statement and ARPANSA's Business Plans.

Performance reporting

ARPANSA's success in achieving its outcome is measured against specific deliverables and key performance indicators in the Portfolio Budget Statements 2012–13 and performance is described in Part 3.

Our History
Prior to 1998 Commonwealth radiation sources and practices were not regulated at a Commonwealth level


The Australian Radiation Laboratory established as the Commonwealth Radium Laboratory, responsible for providing advice to Government and the community on health effects of radiation, and for undertaking research and providing services in this area.


The Australian Radiation Laboratory conducts preliminary studies on former British atomic test sites at Maralinga indicating significantly higher contamination levels than previously reported.


The Australian Radiation Laboratory's findings convince the Australian Government to set up a technical assessment group to oversee further technical studies of Maralinga site and advise on rehabilitation options.


The Nuclear Safety Bureau is established and operated under Part VIIA of the Australian Nuclear Science and Technology Organisation (ANSTO) Act 1987 and given reponsibility for regulating the HIFAR and Moata research reactors at Lucas Heights in Sydney.


Australian Radiation Laboratory scientific experts commence work as part of the Maralinga Rehabilitation Technical Advisory Committee – a whole of Government initiative – to evaluate radiological risks and develop an effective clean-up and land remediation of contaminated sites to minimise risks to potential inhabitants from radiation exposure.


Work on the Maralinga Rehabilitation Technical Advisory Committee Project commences during which Australian Radiation Laboratory and later ARPANSA, takes comprehensive measurements of the site. Project teams remove large quantities of plutonium-contaminated soil from three sites for safe containment in purpose-built burial trenches. Completion of the Project results in much lower levels of radiation than was predicted in the original MARTAC report.

'As the Commonwealth regulator, our mandate covers ionising and non-ionising radiation, safety and security of nuclear installations and radioactive sources, and preparedness and response to accidents or malicious acts involving radiological hazards.'




Responsibility for the Australian primary standard of absorbed dose in medical radiation exposures is transferred to the Australian Radiation Laboratory, as provided for by the National Measurement Act 1960.


The Federal Government announces that it will combine the Australian Radiation Laboratory and the Nuclear Safety Bureau and establish ARPANSA as a new regulatory body with underpinning legislation - the Australian Radiation Protection and Nuclear Safety Act 1998 (the ARPANS Act).
