Measurement of Radiation Exposure Rates Around the Radiology Examination Room in the Emergency Department of Gunung Jati Regional General Hospital

Abstrak

The Emergency Department (ED) is a high-risk place for radiation exposure because patients are seen quickly, there are a lot of patients, and the environment is very complicated. This study assessed the radiation exposure levels in the vicinity of the ED radiology examination room at RSD Gunung Jati, Cirebon, thereby addressing a significant deficiency in annual safety monitoring and apprehensions regarding structural integrity. Using a descriptive quantitative method, measurements were taken at six key locations, which were divided into Area C (occupational) and Area E (public), with a calibrated Fluke survey meter (CF: 1.01 μSv/h). To simulate clinical scatter conditions, standardized exposure factors of 75 kVp and 20 mAs were used. The results showed that all measurement points adhered to national BAPETEN rules and internal dose limits very closely. The highest yearly dose of radiation for workers was 0.205 mSv/year (less than 1% of the 20 mSv/year limit), and the highest dose for the public was 0.083 mSv/year (about 9% of the 1 mSv/year limit). Although there were initial concerns about door seals that weren't hermetic, the results show that the current spatial separation and structural shielding do a good job of preventing dangerous radiation from leaking. This study finds that the facility successfully follows the ALARA principle in its current operation. However, it is recommended that annual radiological audits become a regular part of the process and that lead-lined doors be structurally repaired to ensure long-term safety margins as clinical needs evolve. These results give regional emergency radiology units an important safety baseline.
