There are about 110 accredited educational programs recognized by the American Registry of Radiologic Technologists (ARRT).

Important Qualities for Radiation Therapists

Interpersonal skills. Radiation therapists work closely with patients. It is important that therapists be comfortable interacting with people who may be going through physical and emotional stress.

Physical stamina. Radiation therapists must be able to be on their feet for long periods and be able to lift and move patients who need assistance.

Technical skills. Radiation therapists work with computers and large pieces of technological equipment, so they must be comfortable operating those devices.

In most states, radiation therapists must be licensed or certified. Requirements vary by state, but typically include graduation from an accredited radiation therapy program and ARRT certification.
