About the Personal Radiation Monitoring Service (PRMS)

ARPANSA Building in Yallambie, Victoria

Since 1932, the Australian Radiation Protection and Nuclear Safety Agency (ARPANSA) has operated a Personal Radiation Monitoring Service for measuring doses that people who are occupationally exposed to radiation may receive.

About the PRMS

ARPANSA and the National Occupational Health and Safety Commission (NOHSC) have established radiation protection standards and have set annual effective dose limits for radiation workers in order to minimise the chance of adverse effects occurring. These standards recommend that the annual dose received by radiation workers should not exceed 20,000 microsievert (µSv), averaged over 5 years, with no more than 50,000 µSv in any one year.

By the consistent wearing of monitors, it is possible to determine the annual dose received by each individual and to establish that the amount of radiation received by these people is below the recommended limits.

The PRMS is accredited by the National Association of Testing Authorities (NATA Accredited Laboratory Number 14442). All measurements are performed in accordance with the NATA requirements which include the Standard General requirements for the competence of testing and calibration laboratories (ISO/IEC 17025). All doses are traceable to Australian Primary Standards. A comprehensive quality assurance program underpins the reliability and quality of the Service.

Who needs to be monitored?

Any worker who is likely to be exposed to radiation over a long period of time as a result of their employment should be monitored.

Personal monitoring is useful for assessing the effectiveness of radiation protection. It can be used for documenting the occupational doses of wearers, especially when the wearer is accidentally exposed, and to identify inadequate or improper radiation protection practices.

The requirement for specific occupations to be monitored varies from State to State. Please check these requirements with your State Regulatory Authority.

Dose records and the PRMS database

Monitors are issued regularly for a 4, 8 or 12 weekly wearing period. At the end of each period, the monitors are returned to the PRMS for processing and assessment of the doses recorded by them. The Dose Report issued to each Centre lists the doses received by each monitor and the accumulated doses received in the last twelve month period for each wearer.

The dose records of all individuals monitored by the Service are kept indefinitely by the Australian Radiation Protection and Nuclear Safety Agency.

Since 1986, each wearer registered with the Service has had their doses recorded on the PRMS Database of Occupationally Exposed Persons which is maintained by the Australian Radiation Protection and Nuclear Safety Agency. This enables a complete dose history of each person monitored by the Service to be maintained, no matter where they work.
