Radiation Therapy is the medical specialty that utilizes ionizing radiation in the treatment and cure of malignant disease. The Radiation Therapist is an integral member of the cancer management team and works in tandem with the Radiation Oncologist (physician specializing in cancer treatment) in delivering a prescribed course of radiation therapy. Responsibilities of the Radiation Therapist include localization of tumor volume (simulation), treatment planning (dosimetry), and the daily delivery of radiation treatments, as well as providing comfort and support to patients and their families.

The Radiation Therapist is a highly motivated and emotionally mature individual who has a sincere desire to be a member of the health care team. A high degree of accuracy, attention to detail and personal integrity is essential. The Radiation Therapist must be willing to accept responsibility and provide understanding and compassion to the patient and the issues they face in dealing with their illness.

To become a registered Radiation Therapist in the United States it is necessary to pass the national certification examination in Radiation Therapy offered by the American Registry of Radiologic Technologists (ARRT). Eligibility for this exam is achieved through successful completion from an accredited radiation therapy program.

Individuals wishing to enter City of Hope's School of Radiation Therapy must make application to the program and meet the established admission requirements.
