2.Scope 2.1 This practice defines a structured method for determining the continued suitability of the protective articles worn and used by healthcare personnel whose work exposes them to X-Rays. It provides a systematic approach for visual, tactile, and X-Ray inspection, and it establishes requirements for article identification, inspection status, and the reporting of inspection results. 2.6.2 This practice does not address the attenuation characteristics of the inspected articles, but does estimate the extent of areas that have clearly been torn, weakened, stretched, or have otherwise deteriorated during use. For measuring the attenuating characteristics of the protective material used in radiation protective garments, see ASTM F 2547.
3.Significance and Use 3.1Radiation protective garments (typically called leads) are used by physicians, nurses, and technicians who must be present when x-rays are being generated during diagnostic or therapeutic procedures. These garments must be periodically inspected to ensure their continued suitability. Visual inspection will not reveal holes, cracks, or other deterioration that may have occurred in the protective material underlying the covering fabrics. Only x-rays can provide the necessary information. Fluoroscopy, a form of x-ray generation, is typically used to image the protective garments, but its use exposes the inspector to radiation, and so should be used judiciously. 3.2This practice provides a means of identifying and quantifying the cumulative area of any holes or areas of deterioration on an inspection item, and it establishes rejection limits based on the location of the defects: over the thyroid gland, over vital organs, or in other, less sensitive locations. 3.3 Though this practice is primarily intended for the inspection of articles to determine continued suitability, the inspections described in this practice could be applied to the evaluation of new products prior to first use. 3.4While protective clothing is intended to reduce exposure to radiation in accordance with the ALARA principle (As Low As Reasonably Achievable), personal dosimeters provide the most reliable measure of radiation exposure. This practice does not address the operation of dosimeter radiation safety systems.
