Become A Dosimetrist

Most radiation therapists complete programs that lead to an associate’s degree or bachelor’s degree in radiation therapy. Radiation therapists must be licensed or certified in most states. Requirements vary by state, but often include passing a national certification exam.

Employers usually prefer to hire applicants who have an associate’s degree or a bachelor's degree in radiation therapy. However, candidates may qualify for some positions by completing a 12-month certificate program.

Radiation therapy programs include courses in radiation therapy procedures and the scientific theories behind them. These programs often include experience in a clinical setting and courses in human anatomy and physiology, physics, algebra, computer science, and research methodology. In 2014, there were about 120 accredited educational programs recognized by the American Registry of Radiologic Technologists.

Detail oriented. Radiation therapists must follow exact instructions and input exact measurements to make sure the patient is exposed to the correct amount of radiation.

Interpersonal skills. Radiation therapists work closely with patients. It is important that therapists be comfortable interacting with people who may be going through physical and emotional stress.

Physical stamina. Radiation therapists must be able to be on their feet for long periods and be able to lift and move patients who need assistance.

Technical skills. Radiation therapists work with computers and large pieces of technological equipment, so they must be comfortable operating those devices.

In most states, radiation therapists must be licensed or certified. Requirements vary by state, but typically include graduation from an accredited radiation therapy program and American Registry of Radiologic Technologists (ARRT) certification.

To become ARRT certified, an applicant must complete an accredited radiation therapy program, adhere to ARRT ethical standards, and pass the ARRT certification exam. The exam covers radiation protection and quality assurance, clinical concepts in radiation oncology, treatment planning, treatment delivery, and patient care and education. A list of accredited programs is available from ARRT.

Many jobs also require cardiopulmonary resuscitation (CPR) or basic life support (BLS) certification.

With additional education and certification, therapists can become medical dosimetrists. Dosimetrists are responsible for calculating the correct dose of radiation that is used in the treatment of cancer patients.
