Radiation Therapy

Radiation TherapyCareer Information

The radiation therapist functions as a member of the team of physician (Radiation Oncologist), physicist, dosimetrist, and nurse to provide treatment using ionizing radiation sources for patients with malignant and some benign diseases. The radiation therapist is responsible for the daily delivery of the prescribed treatment according to the treatment plan prepared by the physician in consultation with the medical physicist. The therapist works with the oncology nurse in the daily assessment of the patient's status and needs during their course of therapy.

Radiation therapists are employed in radiation therapy facilities located in hospitals and freestanding centers. Individuals who have the necessary qualifications may be employed in educational programs sponsored by hospitals, colleges, or other qualified centers. Therapists can function as dosimetrists with additional education or experience. A limited number of positions for certified therapist are available in research facilities of various types.

Program Information

This two-year program is selective and competitive; acceptance is not guaranteed. Students must satisfy all UI admission requirements, complete all prerequisites, and be accepted into the Radiation Therapy professional program following an application and selection process.

Radiation Therapy

The radiation therapy professional program teaches theory and techniques of radiation therapy technology.  In conjunction with clinical rotations at the University of Iowa Hospitals and Clinics under the close guidance of licensed radiation therapists, students complete coursework in patient care, radiation safety, pathology, medical physics, radiation therapy principles, medical ethics, sectional and vascular anatomy, research methodologies, and CT and/or MRI courses. Emphasis is placed on competence in areas of oncology treatment planning, treatment delivery, dosimetry, and use of megavoltage radiation-producing equipment to administer treatment.

Upon completing the program, graduates are eligible to apply for the national certification exam in radiation therapy. Students will have completed the course work but not the clinical component to be eligible to apply for the national certification exam in computed tomography and/or magnetic resonance imaging.

Students typically apply to this two-year program during their sophomore year and begin it in fall of their junior year. Application deadline is January 15.  Seven students are accepted into this track each year.

Radiation Oncology Clinical Internships

The Department of Radiation Oncology is staffed by 15 registered radiation therapists, 7 physicians, 13 physicists, 7 dosimetrists, and 10 nurses. These highly qualified professionals work together to treat approximately 1450 cancer patients per year. The department uses state-of-the-art imaging techniques to deliver a wide array of effective radiation therapy treatment delivery. Some of these delivery techniques include stereotactic body radiation therapy, stereotactic radiosurgery, intra-operative radiation therapy, high dose rate brachytherapy, external beam radiation therapy, and intensity modulated radiation therapy. Accepted students have clinic rotations at UIHC’s main campus and an outreach clinic – Iowa City Cancer Treatment Center located at 3010 Northgate Dr, Iowa City, IA 52245.
