Pengukuran Laju Paparan Radiasi dan Efektivitas Perisai Radiasi Pada Ruang Panoramik di RSUD Dr.Pirngadi Kota Medan”

Abstract

Research has been carried out on measuring the rate of radiation exposure and the effectiveness of radiation shielding in the panoramic room at RSUD DR. Pirngadi, Medan City. This research aims to determine the amount of radiation and the effectiveness of the walls of the panoramic room in absorbing radiation emitted by the panoramic aircraft, as well as knowing the level of safety in the room around the panoramic room in accordance with the dose limit values for workers and the surrounding community. Measurements were carried out at several points on the walls of the panoramic room using a radiation measuring instrument, namely the Babyline Surveymeter. The results showed that the amount of radiation at the rear point of the entrance was 0.0002362 mSv/year, the point behind the operator's glass was 0.000288 mSv/year, the toilet wall point behind the source was 0.0009216 mSv/year, the corridor point was 0 mSv/year. year, rear wall point of source archive room is 0.00016992 mSv/year. Where these values do not exceed tolerance limits and meet BAPETEN regulatory standards No.8 of 2011. The effectiveness results for each barrier point are 96.47% for door barriers, 90.9% for operator glass barriers, 80% for toilet walls. , Corridors at 100%, Archive room walls at 96.72%. The research results show that the effectiveness of the wall is only able to absorb radiation of more than 90%, with the wall category still being very good and in accordance with predetermined standards.
