Radiation therapists typically work hand-in-hand with specialists administering chemotherapy and surgery. They keep a record of patient’s treatments and progress in order to determine the minimum amount of radiation needed for cancer prevention and elimination. Radiation therapists are considered a specialty position for advanced radiologic technologists.
