Radiation engineers maintain, service and repair radiotherapy equipment for use by medical professionals. They are not subject to statutory regulation, but may join a register that is accredited by the PSA. The Accredited Register for radiation engineers is the Register of Clinical Technologists.
The Register of Clinical Technologists (the RCT) is a register for healthcare scientists concerned with the practical application of physics, engineering and technology to clinical practice. Clinical technologists work in National Health Service (NHS) hospitals, private health care, academic institutions and the medical device industry.
