X-Ray Radiation Exposure Rate on the Walls of ATRO Bali Diagnostic Laboratory

Abstract

Research has been carried out on the rate of exposure to X-ray radiation on the walls of the ATRO Bali diagnostic laboratory. The dose of X-ray radiation exposure was measured using a surveymeter indoors and outdoors on the primary radiation retaining wall (A), secondary radiation retaining wall (B and D) and leakage radiation retaining wall (C) by setting the exposure factor at 80 kV tube voltage, 200 mA tube current and 0.160 seconds time. The results of the radiation exposure dose measurement on all walls are used to calculate the radiation exposure rate. The results of the calculation of the average rate of exposure to X-ray radiation on wall A is 1.106 × 10-7 mR/h, wall B is 1.600 × 10-7 mR/h, wall C is 6.217 × 10-8 mR/h and wall D of 7.668 × 10-8 mR/h. The results of the calculation of the rate of exposure to X-ray radiation on the walls outside the laboratory were obtained at 0 mR/hour. From these results it can be seen that the rate of exposure to X-ray radiation in the Bali ATRO diagnostic laboratory is still below the dose limit value (NBD) recommended by Bapeten Perka No. 8 of 2011 amounted to 0.57 mR/h for radiation workers and 0.03 mR/h for the community.
