Overview

Radiation therapy involves the use of ionizing radiation to treat cancer within the human body. It is the job of the radiation therapist to assist the radiation oncologist (a physician specializing in treating cancer with radiation) in the application of treatment by exposing specific areas of the patients body to prescribed dosages of radiation. The primary responsibilities of the radiation therapist are operation of the therapeutic equipment, proper patient positioning, monitoring of the patient during the procedure, and related clerical duties. Due to the nature of radiation therapy, the therapist is responsible to adhere to strict radiation safety guidelines. The successful therapist must demonstrate good communication skills and the ability to work with patients who are under a great deal of stress.

Training

A high school diploma or GED is required for those wishing to enter a radiation therapy program. Training in radiation therapy consists of a 2-4 year program leading to either an associates or bachelors degree and is available in colleges and universities. One year certificate programs are available for students who have successfully completed a bachelors or associates program in radiologic technology. Radiation therapists require certification by the American Registry of Radiologic Technologists (ARRT) and will need to acquire continuing education credits in order to renew certification. In addition, many states also require a separate licensure for therapists. State requirements for licensure will vary dependent upon individual states requirements.

Job Prospects

Radiation therapists are primarily employed by hospitals and free standing radiation oncology centers, with the majority of therapists working a 40 hour week. The current and future job prospects for radiation therapists is very good with overall job growth expected to be faster than average for the next several years. This is primarily due to the aging population which requires more medical services and the strong emphasis on the early detection and treatment of cancer.
