Regulations are required to give effect to the Radiation Act 2005 (the Act).
Many requirements in the Radiation Regulations 2017 have been drawn directly from national codes and standards that are required to be implemented by all jurisdictions in Australia pursuant to national agreements.
Under the Radiation Regulations 2017, the security of high consequence sealed sources and high consequence groups of sealed sources have been strengthened, and the occupational dose limits to the lens of the eye have been lowered to reflect recent international developments.
The Radiation Regulations 2017 prescribe:
- the activity concentration and activity of material that spontaneously emits ionising radiation and the prescribed circumstances for the purposes of the definition in the Act of the term 'radioactive material'
- radiation dose limits
- the radiation sources that require a current certificate of compliance before use of the source
- the date of expiry for certificates of compliance issued in respect of prescribed radiation sources
- radionuclides and D values for prescribed radionuclides
- identification documents
- other matters required to give effect to the Act.
Eye dose limits for workers
It has been nationally agreed that the equivalent dose limit for the lens of the eye for occupational exposure be reduced from 150 mSv per year to 20 mSv per year, averaged over 5 years, with no dose in a single year to exceed 50 mSv.
In Victoria, this change to the dose limit for the lens of the eye is implemented by the prescribed dose limit in Schedule 4 of the Radiation Regulations 2017. The dose limits in the regulations are consistent with the limits specified in the Code for Radiation Protection in Planned Exposure Situations, published by the Australian Radiation Protection and Nuclear Safety Agency (ARPANSA).
