Programs that treat people who have a particular illness or condition through the application of chemical reagents which have a specific and toxic effect upon the disease-causing organism, or through the use of radioactive substances including radioactive isotopes and ionizing radiation to kill diseased cells. Included are radioactive implants, x-ray radiation therapy and supervoltage and megavoltage treatments with specialized equipment including cobalt units, linear accelerators with or without electron team therapy capability, betatrons and van de Graff machines.
Programs that are staffed by specialists who have expertise in the diagnostic and therapeutic utilization of the nuclear properties of radioactive and stable nuclides including radioimmunoassay; therapy with radioisotopically labelled antibodies; positron emission tomography (PET); and single-proton emission computerized tomography (SPECT). Additionally, the nuclear medicine physician has special knowledge in the biological effects of radiation exposure; the principles of radiation safety and protection; the management of patients who have been exposed to ionizing radiation; and special knowledge in the physical sciences encompassing the fundamentals of nuclear physics and nuclear magnetic resonance and the principles and operation of radiation detection and nuclear imaging instrumentation systems.
