Radiological technologists operate X-ray, radiographic and fluoroscopic equipment, specialized CT scanners and mammography units to produce images of the body for use by radiologists in the diagnosis of disease or injury.

Nuclear medicine technologists operate radiation detection equipment such as gamma cameras, scanners, scintillation counters and ionization chambers to acquire information for use by nuclear medicine physicians in the diagnosis of disease.

Radiation therapists operate linear accelerators, and cobalt-60, X-ray and other radiation therapy equipment to administer radiation treatment prescribed by radiation oncologists.

To be a medical radiation technologist, you need a two- to three-year college, hospital, school or other approved program in your area of specialization.

You may specialize in diagnostic radiography, nuclear medicine technology or radiation therapy.

You also need a period of supervised practical training.

You may need a licence in the province/territory where you'll work.

You must be certified by the national association Canadian Association of Medical Radiation Technologists in all provinces except Quebec.

With experience, you may move up the ranks to become a supervisor or instructor.

Most recent entrants have a community college diploma, and almost 3 in 20 have an undergraduate university degree.
