Radiation therapists provide radiation therapy to patients as prescribed by a radiologist according to established practices and standards. They review prescription and diagnosis, act as a liaison with physician and supportive care personnel, prepare equipment, such as immobilization, treatment, and protection devices. They maintain records, reports, and files and may assist in dosimetry procedures and tumor localization.

An associate degree or bachelor’s degree is typically required to work as a radiation therapist who treats cancer patients using radiation therapies. Radiation therapists must maintain safety, keep accurate patient records and work closely with patients to provide support and answer questions.
