Radiation Therapy (AAS)

Nature of Work

Radiation Therapists apply knowledge of human anatomy and physiology, oncology, radiation techniques, treatment planning and dosimetry in their work. Effective communication with patients, health professionals, and the public is essential. Competence and compassion must be displayed in meeting the special needs of the oncology patients.

Radiation Therapists do the following:

  • Administer a prescribed course of radiation therapy, provide patient care, and maintain treatment records.
  • Evaluate and assess the radiation delivery, the responses of the patient, and ensure the quality of care.
  • May also do tumor localization, patient follow-up, and patient education.
