    Educate, prepare, and reassure patients and their families by answering questions, providing physical assistance, and reinforcing physicians' advice regarding treatment reactions or post-treatment care.

    Review prescription, diagnosis, patient chart, and identification.

    Follow principles of radiation protection for patient, self, and others.

    Position patients for treatment with accuracy, according to prescription.

    Observe and reassure patients during treatment and report unusual reactions to physician or turn equipment off if unexpected adverse reactions occur.

    Photograph treated area of patient and process film.

    Check radiation therapy equipment to ensure proper operation.

    Schedule patients for treatment times.

    Check for side effects, such as skin irritation, nausea, or hair loss to assess patients' reaction to treatment.

    Prepare or construct equipment, such as immobilization, treatment, or protection devices.

    Train or supervise student or subordinate radiotherapy technologists.

    Enter data into computer and set controls to operate or adjust equipment or regulate dosage.

    Conduct most treatment sessions independently, in accordance with the long-term treatment plan and under the general direction of the patient's physician.

    Act as liaison with physicist and supportive care personnel.

    Help physicians, radiation oncologists, or clinical physicists to prepare physical or technical aspects of radiation treatment plans, using information about patient condition and anatomy.

    Provide assistance to other healthcare personnel during dosimetry procedures and tumor localization.

    Calculate actual treatment dosages delivered during each session.

    Implement appropriate follow-up care plans.

    Store, sterilize, or prepare the special applicators containing the radioactive substance implanted by the physician.

    Assist in the preparation of sealed radioactive materials, such as cobalt, radium, cesium, or isotopes, for use in radiation treatments.
