At dose levels commonly found in diagnostic radiology, the overwhelming effect in both adult and paediatric patients is believed to be an increased incidence and associated mortality from stochastic effects. In a field in which technology is advancing rapidly and where unexpected and unique problems continually occur, this At the end of this period, collect all rejected radiographs and determine the actual number of radiographs exposed (i.e., the number of sheets of raw films consumed) during this period. The committee in a non-hospital facility might be composed of a physician, radiologic technologist, office manager and service representative. The .gov means its official. The minimum spatial resolution at the center of the beam for a 6 inch field of view (FOV) is 2 line pairs per mm. The age limit for use of gonad shielding. Three values based on this system are grouped with two additional values to provide an ethical framework for application in diagnostic imaging. 145, Radiation Protection in Dentistry, Gray, J.
