Abstract

The measurement of radiation dose in diagnostic radiology and radiotherapy is considered to be some critical factor+s in optimizing radiation protection for healthcare practitioners, patients and public. This article presents the overview of an average radiation dose measurement in public area around Radiology Unit in Dr. Saiful Anwar Hospital (RSSA), Malang. The critical radiation dose recommendation from BAPETEN is below 50 mSv/year for healthcare practitioners and below 5 mSv/year for public area. This radiation dose measurement was done outside the CT Scan room, radiotherapy Cobalt-60, brachytherapy and fluoroscopy room, and X-ray room, using RGD 27091 survey meter. The measurement of radiation background was held while all instruments producing radiation were in standby position. The average value of radiation background around radiology unit was 0.83 µSv/h. The lowest dose rate measurement was 0.6 µSv/h at CT scan area, and the highest dose rate measurement was 3.57 µSv/h, which was in front of the brachytherapy unit’s door. The measurement results show that the scattered radiation dose around radiology unit is lower than the critical radiation dose recommendation from BAPETEN.
