How to become a Radiation Therapist

To become a radiation therapist, you typically need an associate or bachelor's degree in radiation therapy. Many programs require prerequisite courses in anatomy, physics, and math. Clinical training is a core part of the curriculum.

After graduating, you must pass the American Registry of Radiologic Technologists (ARRT) exam to earn certification. Most states require this certification or a state license to practice. Continuing education is needed to maintain credentials.

  • Earn an associate or bachelor's degree in radiation therapy from a program accredited by the Joint Review Committee on Education in Radiologic Technology (JRCERT).
  • Complete clinical rotations as part of your program — typically 1,200+ hours of hands-on experience.
  • Pass the ARRT certification exam in radiation therapy.
  • Obtain state licensure if required (most states do).
  • Renew certification every two years with continuing education credits.

Job outlook

The BLS projects employment for radiation therapists will grow 1.9% from 2024 to 2034, slower than the average for all occupations. That translates to about 900 job openings each year, mostly from retirements and workers leaving the field.

Currently, 17,070 people work as radiation therapists in the U.S. The slow growth reflects advances in cancer treatment that are more precise and require fewer sessions per patient. Still, an aging population will sustain demand for radiation therapy services. Competition for jobs may be stronger in metropolitan areas.
