Radiation therapists administer radiation treatments to cancer patients under the direction of radiation oncologists. Many states require radiation therapists to be licensed due to the safety implications of working with ionizing radiation.

What If My State Doesn't Require a License?

Even if your state does not mandate a state-level radiation therapist license, you may still need to meet local requirements. Many cities and counties impose their own licensing, registration, or permit requirements. Additionally, voluntary certification from professional organizations can enhance your credibility and job prospects. Always check with your local government and relevant professional associations.

If your state requires a radiation therapist license, requirements typically include completing an approved education or training program, passing an exam, and submitting an application with applicable fees. Specific requirements vary by state — visit your state's licensing board website (linked in the table above) for detailed information on the application process.
