Radiation compliance certificates and registrations
Register a radiation place
A radiation place is anywhere a radiation source is used or stored.
Before you register
Before you apply to register for a radiation place follow these steps.
Step 1. Get a radiation shielding assessment
Shielding helps to keep radiation exposure at acceptable levels for both radiation workers and visitors.
Before you register a radiation place, you need an accredited company to assess radiation shielding of your practice. Read the list of accredited NT radiation companies.
Step 2. Get a certificate of compliance
You need a certificate of compliance for each radiation source and radiation place before you can register a radiation place.
A licensee must not use a radiation source unless a certificate of compliance for a radiation place is prominently displayed.
Compliance certificates ensure the radiation place is safe to occupy, and that radiation sources are safe to use.
Step 3. Read the information about shielding requirements
Shielding requirements are listed below.
Shielding design goals
Medical facilities must follow the requirements outlined in the Northern Territory's guideline on shielding design for new or old facilities.
Shielding must achieve ambient dose equivalent rates of the following:
- less than 0.1 mSv per week (a fraction of 5 mSv per year) for controlled areas
- less than 0.02 mSv per week (a fraction of 1 mSv per year) for uncontrolled areas.
A controlled area is a clearly defined area in which occupational exposure is under the control of the principal licence holder.
An uncontrolled area is not supervised. Members of the public may have access.
Once radiation shielding design is completed and shielding installed as per the shielding design, you do not need to assess your shielding again unless you modify the radiation place.You should keep photographs and documents that show the radiation shielding is adequate. If you do not keep all documents, you may need to have your shielding design reassessed and tested.
Modifying a radiation place
Your radiation place registration will expire if you modify your practice or shielding. If this happens you must perform a shielding assessment and get a compliance certificate to register the place again.
For more information download the Radiation Protection Information Sheet No. 806 Process for Registration of a Radiation Place.
