An individual who maintains and safely uses equipment and supplies necessary to demonstrate portions of the human body on X-ray film or fluoroscopic screen for diagnostic purposes, and may supervise and/or teach other radiologic personnel. An estimated 100,000 persons were employed either full-time or part-time as radiologic technologists in 1973: approximately one-third by hospitals, while the remainder work for independent X-ray laboratories, multi-specialty clinics, in physician^ s offices, and in government agencies. American Medical Association Council on Medical Education approved radiologic technology programs are conducted by hospitals and medical schools and by community colleges with hospital affiliation. Programs are open to high school graduates, although a few require 1 or 2 years of college or graduation from a school of nursing. The length of the training varies from a minimum of 2 years in a hospital radiology department, or a junior college in affiliation with one or more hospitals offering an associate degree, to a 4-year university course.
