Radiation therapists work in healthcare facilities or cancer treatment centers. They are on their feet for long periods and may need to lift or turn disabled patients. Because they work with radiation and radioactive material, radiation therapists must follow safety procedures to make sure that they are not exposed to a potentially harmful amount of radiation. This restriction usually means standing in a different room while the patient undergoes radiation procedures.
