Abstract

Diagnostic radiology is the most significant contributor to irradiation in the general population. Unnecessary irradiation of workers, patients, and the public during radiological procedures should be significantly reduced without affecting the medical diagnostic value. This study was conducted to analyze and evaluate the radiation dose rate, radiation protection facilities and radiation worker dose of Radiology Installation of Pariaman Regional Hospital. The method of determining the radiation dose rate at the Radiology Instalansi of Pariaman Hospital uses a PDR 303 gamma surveymeter and the rooms to be measured are CT-Scan rooms, conventional X-rays and mammography. Collecting data on radiation protection facilities, then it will be analyzed based on Nuclear Energy Regulatory Agency Regulation No. 4 of 2020 and radiation worker dose data in 2023 will be analyzed based on Nuclear Energy Regulatory Agency Regulation No. 4 of 2013. The results of the study showed that the radiation dose rate around the CT-Scan room was found to be (0.24-1.61) μSv/hour, the conventional X-ray room with irradiation using the minimum exposure factor obtained a radiation dose rate around the room ranging from (0.013-0.33) μSv/hour and with the maximum exposure factor obtained a dose rate around the room of (0.33-1.08) μSv/hour and the mammography room obtained a radiation dose rate of (0.03-0.40) μSv/hour. The radiology room facilities used by Pariaman Hospital are in accordance with the standards set by Nuclear Energy Regulatory Agency Regulation No. 4 of 2020. And the dose rate received by radiation workers at Pariaman Hospital is below the Dose Limit Value set by Nuclear Energy Regulatory Agency Regulation No. 4 of 2013. Based on the results of this study, it is found that there are several measurement points in the CT-Scan and conventional X-ray rooms that exceed the community dose limit value.

Abstract

Based on the study of radiation dose rates in the Radiology Installation of Pariaman Regional Hospital using a Raysafe surveymeter, it can be reported that the radiation dose rate in the CT-Scan room is measured at (0.30-1.27) μSv/hour. In the conventional X-ray room, the radiation dose rate is found to be between (0.2-0.5) μSv/hour, while in the mammography room, the dose rate ranges from (0.00-0.40) μSv/hour. These findings indicate that the highest radiation exposure occurs in the CT-Scan room, which aligns with the higher complexity and intensity of the imaging procedures performed there. The relatively low dose rates in the conventional X-ray and mammography rooms suggest effective radiation shielding and adherence to safety protocols. Continuous monitoring of radiation levels is essential to ensure they remain within safe limits for both patients and medical staff. Furthermore, this data can be instrumental in optimizing exposure parameters, helping to minimize unnecessary radiation exposure while maintaining diagnostic quality. Implementing regular training for staff on radiation safety practices is also critical, as it enhances awareness and adherence to established protocols. Overall, these measures contribute to a safer radiology environment for all involved.
