  • Evaluates and records daily patients’ side effects or adverse reactions, both physiologic and psychologic responsiveness such as vomiting, hair loss, or anxiety.
  • Use high technology equipment including linear accelerators, X-ray imaging machines, computer tomography scans, and fluoroscopy.
  • Therapists work in hospitals or cancer treatment centers.

Advantages and Disadvantages

Getting Started

High school courses should include advanced math, chemistry, biology, anatomy & physiology, and critical thinking.

  • The only training program in Wisconsin is at the University of Wisconsin-LaCrosse. A Bachelor’s Degree, Associate Degree, or Certificate in Radiation are usually required to obtain a position. Many States require Radiation Therapists to be licensed, though Wisconsin is not one of them.
  • UW-LaCrosse offers a Bachelor’s Degree in Radiation Therapy and requires a minimum of six semesters in Pre-Professional and Professional core courses prior to the senior clinical internship. The clinical internship begins in July of the senior year, lasts for 13 months, and is spent at an affiliated hospital clinical internship site. Admission to the major is on a competitive basis. Upon acceptance, students may then register for the professional core courses. Students who successfully meet program requirements interview at clinical sites. Upon selection by one of the sites, students will be placed in their senior clinical internship and will most likely relocate.
  • Mayo School of Health Sciences at Mayo Clinic in Rochester, MN offers a 12 month Radiation Therapy Program. Applicants must have completed an accredited radiography program with a GPA of 3.0 or higher; documented observation experience in radiation oncology; and have specific prerequisite college course work. www.mayo.edu/mshs/rt-rch-admissions.html
  • Pre-professional course requirements include English Composition, Speech/Oral Communication, College Algebra, Anatomy & Physiology.
  • Professional Core courses include Genetics, Radiology of Cancer, Radiobiology, Health Communications, US Health Systems, Radiation Readings, Writings, and Research, Patient Care Issues, Imaging, Radiation Physics, and Medical Terminology.

  • Upon completion of an accredited AND recognized by ARRT program in Radiation Therapy, graduates are eligible to apply to take the national examination offered by ARRT to become Certified.
  • Currently (2015) a Bachelor’s Degree, Associate Degree, OR Certificate in radiation is required by ARRT for application to take exam for Certification. On or after 2015 eligibility requirements for application to take exam for Certification (ARRT) in Radiography, Nuclear Medicine Technology, and Radiation Therapy will call for a candidate to have earned an Associate Degree (or more advanced degree) from an appropriately accredited AND recognized by ARRT institution. The Associate Degree can be in any major when combined with a Clinical Program in Radiation Therapy; it will satisfy the general education requirements. Prerequisites for admission into specific Clinical Radiation Therapy Programs vary.
