Radiation Therapist experience requirements

During training programs, radiation therapy students usually participate in a clinical placement that allows them to work with patients under close supervision. This experience helps prepare Radiation Therapists to administer treatments independently after graduation.

As a result, a Radiation Therapist may not need additional work experience to carry out their job duties. However, you may specify that a few years of experience is a preference or requirement in your radiation therapy job description. This experience could be helpful if your new hire is expected to care for patients with complex cases or a high volume of patients.
