How do protected titles apply to medical radiation practice?
Medical Radiation Practice
Published on 6 Dec 2025
As a registered medical radiation practitioner you are legally allowed to use the title of your speciality, i.e. nuclear medicine scientist, radiation therapist radiographer etc.
However, anyone can call themselves a sonographer or MRI technologist as these are not protected titles. Identifying yourself using a protected title for which you aren’t registered is against the law and can have legal and financial consequences.
What is a protected title?
In Australia, certain health profession titles are legally protected. This is important because they serve as a kind of shorthand for patients and consumers. When you see someone using a protected title, such as ‘radiation therapist’, you can be confident that the person has completed the required training, is properly qualified, and is registered to practise in that profession. It is also expected that they will uphold safe and professional standards. This reassures patients that the care they receive will meet the standards set by law.
How do protected titles apply to medical radiation practitioners?
Medical radiation practitioners have been a nationally regulated health profession since 1 July 2012.
They must be registered with the Medical Radiation Practice Board of Australia and meet the Board's registration standards.
The Board has three divisions of practice, and registered practitioners must be qualified in at least one:
- diagnostic radiography
- radiation therapy
- nuclear medicine technology
You must be registered appropriately if you want to use a protected title. The protected titles for medical radiation practice are:
- medical radiation practitioner
- diagnostic radiographer
- radiographer
- medical imaging technologist
- nuclear medicine scientist
- nuclear medicine technologist, and
- radiation therapist
You could be fined for using a protected title without being registered. There are also fines for ‘holding out'. This is when a person uses a title, name, initial, symbol, word or description which could be reasonably understood to indicate that they are qualified or registered to practise as a medical radiation practitioner.
What are the obligations that come with registration?
Being registered as a medical radiation practitioner is about more than just the ability to use a protected title. It means you agree to meet the high standards of health care delivery as set out by the National Registration and Accreditation Scheme and overseen by the Medical Radiation Practice Board of Australia.
Registration means agreeing to continuing professional development (CPD) and holding appropriate professional indemnity insurance. It also means your name and place of work will be listed on the online national Register of Practitioners (unless an exemption has been granted). Any conditions attached to your registration will also be listed.
