High school students should study mathematics, physics, chemistry and biology. A high school diploma or equivalent is required for entry into a program. Formal training is offered through hospitals, colleges, universities and vocational/technical schools. Students can enroll in programs that last from 1 to 4 years, and receive either a certificate, associate degree or bachelor’s degree. Individuals with prior experience in the health field such as Medical Technologists or Radiologic Technologists, may enroll in the 1-year programs. Course work in a nuclear medicine technology program covers anatomy, physiology, radiation exposure and protection, procedures, radiopharmaceutical use, and imaging techniques. Upon completion of an accredited program, graduates must pass an examination and meet other requirements before becoming registered by the American Registry of Radiologic Technologists (ARRT) or the Nuclear Medicine Technology Certification Board.
