Dispose of a radiation source
Possession Licensees seeking to dispose of their radiation sources will need to follow a process to ensure the radiation source will not harm people or the environment.
There are different requirements for disposing of different types of radiation sources:
- dispose of radiation apparatus
- dispose of unsealed radioactive material with low concentration levels
- apply for an Approval to Dispose of unsealed radioactive material for elevated concentration levels
Notify Radiation Health within 7 days of disposing of the radiation source. You will remain responsible for the radiation source until this notice has been received. Tracking the disposal of radiation sources is necessary to ensure that safety requirements to minimise the risks involved with radiation are being met.
Dispose of radiation apparatus
If you dispose of your radiation apparatus you need to ensure that:
- the equipment is rendered permanently inoperable, incapable of being repaired, and incapable of producing radiation (for example by destroying the main components, such as the X-ray tube)
- all radiation warning signs are removed (for example radiation hazard signs)
- notice is given within 7 days after disposal to the Chief Executive.
Dispose of unsealed radioactive material with low concentration levels
You can dispose of radioactive material without seeking approval if the concentration or activity of a radionuclide is not more than the maximum calculated using section 9, 10, 11 and 12 of the Radiation Safety Regulation 2021.
Maximum concentration or activity levels vary depending on the radionuclide and how the radiation source is being disposed of:
- for air, water or sewerage system concentration levels see Sections 9 and 10 of the Radiation Safety Regulation 2021
- for concentration levels in all other methods of disposal see Section 11 and 12 of the Radiation Safety Regulation 2021.
These concentration levels need to be achieved before the release of the material into the environment. Disposal of concentrations of radioactive material above these levels is illegal except if authorised by an Approval to Dispose.
Maximum concentration levels for disposal are lower than the concentration levels that require a person to hold a Possession Licence. This helps to ensure that no one receives an unacceptable dose of radiation.
Apply for an Approval to Dispose of unsealed radioactive material for elevated concentration levels
Use this form to apply for an Approval to Dispose of radioactive material when the concentration of a radionuclide is more than the threshold set by the Radiation Safety Regulation 2021.
Your application needs to include:
- details of the radioactive material
- reason for disposing of the radioactive material
- the impact disposal will have on people and the environment, including details of how you will ensure the following criteria will be met:
- no person will receive greater than 300µSv a year as a result of the disposal
- disposal is the best option to protect ecological health and public safety.
