What Does a Radiation Therapist Do? Unlike radiologic technologists who utilize x-rays for diagnostic purposes, radiation therapists are trained to deliver high doses of ionizing radiation to specific areas of the patientâs body for the treatment of disease, specifically cancer.
In radiation therapy (also called radiotherapy), invisible high-energy rays or beams of subatomic particles are used to damage cancer cells and can stop them from growing and dividing. This ultimately can kill the cancer cells treated with radiation. A specialist in radiation therapy is called a radiation oncologist.xternal radiation therapy is usually given on an outpatient basis in a hospital or clinic with specialized equipment 5 days a week for a number of weeks. Patients are not radioactive during or after the treatment with external beam radiation therapy.
