Abstract |
|
|
| This study presents a comprehensive analysis of radiation exposure levels over 30 days in a medical facility, focusing on six specified locations (R1 to R6). Measurements were consistently taken at an elevation of one meter above sea level using the RADEYE PRD survey meter. The data, expressed in microsieverts per hour (µSv/hr), highlights variations in radiation dose rates before and after exposure in the X-ray room, entrance, supervised area, ultrasound room, and at the back of the X-ray room. The overall average dose rates, arranged hierarchically, show R2 with the highest radiation level, averaging 0.1053 µSv/hr, attributed to background and scattered radiations inside the X-ray room after exposure. Importantly, all locations exhibit dose rates below the permissible limits set by regulatory bodies. The calculated Annual Effective Dose Rate (AEDR) and Excess Lifetime Cancer Risk (ELTCR) further contribute to the assessment of potential health risks. For instance, R1 has an AEDR of 0.238 mSv/yr and an ELTCR of 0.357 mSv, demonstrating compliance with international standards. |
