AbstractLead aprons are worn by medical workers to reduce the effects of the radiation doses to which they are exposed during radiography and surgery performed with radioscopic apparatus. Regarding the management of such aprons, the Radiation Protection Section of the Japanese Society of Radiological Technology issued the "Guidelines for the Management of Lead Aprons" in 2000, and common management criteria have been set for all institutions. However, we found that the lead aprons used in operating rooms had not been closely inspected before 2014 in our hospital. Thus, we examined the extent of damage of such aprons in our operation room via computed tomography (CT) scout imaging, as well as visual and tactile inspections. Although no abnormality was detected upon visual and tactile inspections, CT images revealed that protective aprons used for 6 years or more had damaged internal radiation shields, thus risking radiation exposure. In response to these results, we fully realized the need to examine the date of the initial use of currently used lead aprons, to routinely perform visual and tactile inspections, and to regularly evaluate the extent of damage to the internal radiation shields via fluoroscopy in cooperation with the radiation management section.
