These changes and a greater understanding of both the . 8600 Rockville Pike National Library of Medicine From a radiological protection perspective, clear justification for radiological examinations and techniques aimed at minimizing radiation dose while providing the required diagnostic information, are essential. The three fundamental principles of radiation protection of patients are justification, optimisation, and the application of doses As Low As Reasonably Achievable (ALARA) (ICRP103) [ 1 ]. New technologies in projection imaging and CT scanning such as digital receptors and automatic exposure control systems have reduced doses and improved image consistency. The following table of statistical data regarding the average number of children expected by potential parents in various age categories during their remaining lifetimes is provided for x-ray facilities that wish to use it as a basis for judging reproductive potential: Methods to provide shielding of the gonads for all patients; Methods to provide shielding of the breast for female patients; Availability of compensating filters to decrease chest exposure; and. Center light field to the center of the cassette at a 40" (100cm) SID.

Implementation problems for radiation protection in medicine possibly flow from apparent inadequacies of the International Commission on Radiological Protection (ICRP) principles taken on their own, coupled with their failure to transfer successfully to the medical world. This guidance also applies to those services using ionising radiation outside of radiology and nuclear medicine departments such as cardiology and orthopaedics. The use of X-ray equipment, particularly CT, in medicine is increasing throughout Australia. Certified equipment shall meet the manufacturers' specifications. The longer life expectancy in children allows more time for any harmful effects of radiation to manifest, and developing organs and tissues are more sensitive to the effects of radiation. If the exposed field size from the larger cassette exceeds the film size for the cassette in the bucky tray, then triangulation utilizing the exposed film from the large cassette must be done to determine the actual field size at the bucky tray.
