Radiological medical physics is an applied branch of physics concerned with the application of ionizing and non-ionizing radiation to the diagnosis and treatment of disease. Professionals in this area are involved with clinical service, consultation, teaching and research. One major service is the planning of radiation treatments for cancer patients. Such treatments use external radiation beams or internal radioactive sources and optimize the tumor-to-healthy tissue dose ratio. An indispensable service is the accurate measurement of radiation output from sources employed in cancer therapy. Other important functions include the investigation of equipment performance, organization of quality control practices, design of radiation installations and control of medical radiation hazards. Such individuals often find their primary responsibilities in radiation therapy, nuclear medicine or diagnostic imaging areas.
