This certificate program is designed for the certified radiation therapist, someone with a BS degree in science or another related field with required prerequisites, or an on-the-job training dosimetrist to continue his/her education in the specialized field of medical dosimetry. “The medical dosimetrist is a member of the radiation oncology team who has knowledge of the overall characteristics and clinical relevance of radiation oncology treatment machines and equipment, is cognizant of procedures commonly used in brachytherapy and has the education and expertise necessary to generate radiation dose distributions and dose calculations in collaboration with the medical physicist and radiation oncologist” (from the A.A.M.D.). Prerequisites for acceptance into the program include certification as a radiation therapist and/or participating in an on-the-job medical dosimetry training program; and/or a BS degree with grades of “C” or better in the following college level courses; pre-calculus math, physics, biology, anatomy & physiology, medical terminology, and computer science; as well as a 40 hour week of observation in medical dosimetry at a radiation oncology center. This program utilizes Web-based instruction for the didactic course work. The clinical practicum courses are taken at affiliated radiation oncology departments. The program includes three semesters and always starts in the fall semester. Track I (32 credits) is for certified radiation therapists; track 2 (23 credits) is for certified radiation therapists or persons with a bachelor’s degree participating in on-the-job training programs.
