Introduction
This section has information for businesses that use or operate radiation sources and radiation apparatus.
It covers topics including:
When to get a certificate of compliance
You need a compliance certificate before you can:
- apply for a licence to possess a radiation apparatus or source
- apply to register a radiation source or apparatus
- apply to register a radiation place.
About certificates of compliance
A certificate of compliance shows that a radiation source:
- is safe to use
- has adequate shielding
- meets Australian Radiation Protection and Nuclear Safety Agency and Northern Territory (NT) codes of practice
- meets relevant Australian standards.
Certificates must be issued by an accredited company. Read the list of accredited NT radiation companies.
Sealed radioactive material
All sealed radioactive material must have a certificate of compliance. This certificate shows that a radiation source is safe to use. It should mention applicable codes of practice and relevant Australian standards.
Compliance certificates must be re-issued at least once every three years.
Wipe test
All radiation sources in storage must be wipe tested at least once every ten years.
For sources in regular use, wipe testing should be carried out at a minimum of every three years.
Sources used in corrosive environments should be wipe tested more frequently.
Roughly treated sources and older radiation sources should be wipe tested much more frequently.
Wipe testing must be carried out as soon as possible if the source housing is significantly damaged.
Wipe testing must follow NT codes of practice.
Unsealed radioactive material
Storage of unsealed radioactive material must be certified by an accredited person. A certificate of compliance ensures that all radioactive material is stored and used in a safe way.
The radiation dose rate at the boundary of the storage facility must be less than 10 μSv/hour.
Radiation apparatus
All radiation apparatus must have a certificate of compliance issued by an accredited person in the NT.
Compliance certificates must be re-issued at least once every three years.
When to test medical diagnostic x-ray equipment
Medical diagnostic x-ray equipment must be tested more frequently.
Apparatus type | Testing frequency |
---|---|
Mobile radiographic | Annual |
Major radiographic | Annual |
Fluoroscopic | Annual |
Mammographic | Annual |
Computed tomographic | Annual |
Cabinet and security | Annual |
Dental | Biennial |
Veterinary | Biennial |
Read the code of practice on quality management for diagnostic radiography for more information.
Radiation shielding
New and modified medical facilities must meet the following shield design goals:
- less than 0.1 mGy per week (fraction of 5 mGy per year) for controlled areas
- less than 0.02 mGy per week (fraction of 1 mGy per year) for uncontrolled areas.
The certificate of compliance may state that it only covers radiation shielding design and is for the purpose of the initial registration of a radiation place.
If any shielding modification takes place, a certificate of compliance must be reissued and the place must be re-registered.
What a certificate of compliance looks like
A certificate of compliance for a radiation place is a letter that:
- is signed
- is dated
- includes the accreditation number and radiation place location
- states that it is a Northern Territory certificate of compliance issued under the Radiation Protection Act.
How to get a certificate of compliance
You can get a compliance certificate from an accredited company. Read the list of accredited NT radiation companies.
Reissue certificate of compliance
Compliance certificates must be re-issued at least once every three years. The certificate must be re-issued immediately if one of the following happens:
- the radiation source is damaged or modified
- the practice is modified.
Contact Radiation Protection for more information about compliance certificates.
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.
Controlled areas
A controlled area is a clearly defined area in which occupational exposure is under the control of the principal licence holder.
Uncontrolled areas
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.

Codes of practice
This page has information about radiation codes of practice in the Northern Territory (NT).
Acquiring a radiation source
A licensee to possess a radiation source may only acquire a radiation source with a current licence to do so. It is a breach of the Radiation Protection Act to acquire a radiation source without a licence that authorises possession and acquire.
Download the acquiring a radiation source code of practice.
Alteration to current radiation protection plan
This code explains and provides regulatory advice for an application to alter an approved radiation protection plan. An application for a variation in the radiation protection plan is simply an application for a licence to possess. You have to pay a fee of $115.
Download the alteration to current radiation protection plan code of practice.
Approved form for certificate of compliance
This code explains and provides regulatory advice for a certificate of compliance for a radiation source or radiation place. The certificate of compliance for a radiation source or radiation place must be re-issued at least at three-yearly intervals. This corresponds to the maximum interval for renewal of all licenses under the Radiation Protection Act. A certificate of compliance may only be issued by a holder of a certificate of accreditation under the Radiation Protection Act.

Certificate of compliance for a radiation place
This code explains and provides regulatory advice for a certificate of compliance for a radiation place. The certificate of compliance for a radiation source or radiation place must be re-issued at least at three-yearly intervals. This corresponds to the maximum interval for renewal of all licenses under the Radiation Protection Act. A certificate of compliance may only be issued by a holder of a certificate of accreditation under the Radiation Protection Act.
Download the certificate of compliance for a radiation place code of practice.
Disposal of a radiation source
A radiation source must not be abandoned. Sufficient funds must be set aside to provide for the safe disposal of all radiation sources. Disposal basically means that the source is no longer useful and is to be decommissioned as waste. A current holder of a licence to possess and sell may sell a radiation source that is useful. Disposal may only occur if the licensee to possess holds a licence to dispose of a radiation source.
Download the disposal of a radiation source code of practice.
Guideline on shielding design
This document is a guideline on obtaining a certificate of compliance for a radiation place.
The responsibility for providing adequate shielding resides with the operator. A certificate of compliance for a radiation place is required to register the radiation place. This certificate of compliance must be obtained from a third party service provider, who holds a current certificate of accreditation. A certificate of compliance provides assurance that shielding is adequate for the practice.
It is recommended that each operator uses the design goals that are shown on page six of this guideline as risk constraints for their practice.
Download the guideline on shielding design code of practice.
Quality management for diagnostic radiography
Third party service providers accredited under the Radiation Protection Act to carry out work defined as install, test, repair, service and decommission may use this guideline in parallel with Service Checks for Diagnostic Equipment.
The required tests are essentially concerned with the radiation safety of x-ray equipment. As patient dose ultimately depends on the complete imaging process, the tests must be supplemented with other radiographic and image quality tests as part of a complete quality management program
Download the quality management for diagnostic radiography code of practice.
Service checks for sealed radioactive material
Third party service providers who undertake maintenance on this type of equipment may use this guideline to issue a certificate of compliance for the equipment. The third party service provider is accredited to carry out work under the Radiation Protection Act. Work is defined as install, test, repair, service and decommission. Conditions may be imposed on the certificate of accreditation.
Download the service checks for sealed radioactive material code of practice.
