Pengukuran laju dosis radiasi untuk keselamatan keamanan ruang pemeriksaan di instalasi radiologi rumah sakit umum daerah Kabupaten Bekasi

Abstract

Radiology installations are supporting facilities in hospitals that utilize X-rays to diagnose a disease. X-rays are a type of ionizing radiation that if not monitored, can cause health problems for radiation workers and the surrounding community. It has been found that there is a door that cannot be closed tightly in one of the radiology installation examination rooms of the Bekasi Regional General Hospital which is suspected of having the potential to cause radiation safety and security problems. This study aims to determine the suitability of the radiation dose rate in the examination room area with the dose limit value determined by BAPETEN to ensure radiation safety and security. The study was conducted through radiation dose measurements in seven different areas which are controlled and uncontrolled areas with measurement points at a distance of 30 cm and 100 cm from the radiation wall. The results showed that the dose rate range in the controlled areas (areas A, B, C, E, and G) was 0.04-8.79 mSv/year at a distance of 30 cm, and 0.0-1.74 mSv/year at a distance of 100 cm. While in uncontrolled areas (areas D and F) is 0.04-0.21 mSv/year at a distance of 30 cm, and 0.00-0.06 mSv/year at a distance of 100 cm. This value shows that all measurement points produce radiation dose rate values that are less than the dose limit value determined by BAPETEN, which is less than 20 mSv / year in controlled areas and 1 mSv / year in uncontrolled areas, so it can be said that the radiology examination room of the Bekasi Regional General Hospital can be categorized as safe.
