Glossary of terms
Radiation therapists work with radiation oncologists. They administer the daily radiation treatment under the doctor's prescription and supervision, maintain daily records and regularly check the treatment machines to make sure they are working properly. Radiation therapists go through a two-to-four year educational program following high school or college, then take a special examination and must be certified by the American Registry of Radiologic Technologists. In addition, many states require that radiation therapists be licensed.
