An overview of the applicability of SNI IEC 61331-1:2016 on Lead apron for medical use

Abstract The use of lead apron for radiation protection is regulated under the Indonesia Nuclear Regulatory Agency (BAPETEN) Decree no. 8 year 2011 about Radiation Safety and Use Diagnostic Interventional Radiological X-Ray Machine. It listed specifications are as follows: having thickness equivalent to 0.2 mm Pb or 0.25 diagnostic 0.35 0.5 interventional use. Further, National Standardization (BSN) had issued SNI IEC 61331-1:2016, providing guidance testing plate materials on using 400 kV x-ray machine 1.3 MeV gamma exposure with narrow beam, measure attenuation ratio air kerma rate. method used determine ratio, build-up factors, coefficient. There were 4 different aprons (A, B, C, D) 9 measurement points. results showed rate without was 0.664 mGy/second, lead-equivalent layer 0.0006 best result produced ranging from 17.2 29.1, showing most homogeneity.
