What Would I Do?

Radiation Therapists may also repair or create equipment such as immobilization, treatment, and protection devices, as well as, assist in tumor localization and dosimetry procedures, which is the process used to calculate radiation dosages. They also maintain records, reports, and files.

They also spend most of their time on their feet. Radiation Therapists generally work at least 40 hours a week. They normally work during the day.
