Abstract

This study was conducted on patients undergoing diagnostic X-ray examinations at King Khalid Hospital (KKH) in Majmaah. The investigation focused on the seven most commonly performed radiographic procedures, encompassing a total of 1,504 patients examined using digital radiography (DR) equipment. Patient radiation doses were assessed by calculating the Entrance Surface Air Kerma (ESAK) and Effective Dose (ED), using measured X-ray tube output and exposure parameters. Based on these measurements, appropriate conversion coefficients were applied. This study also analyzed the 75th percentile distributions of ESAK and Kerma Area Product (KAP) and compared the findings with national and international dose reference levels. This study presents the calculated uncertainty (U) values along with the mean ESAK, KAP, and ED values. The recorded ESAK values ranged from 0.12 to 5.74 mGy, KAP from 0.9 to 1.84 Gy·cm2, and ED from 0.01 to 0.23 mSv. These values were found to be significantly lower than the Diagnostic Reference Levels (DRLs) reported in European and national studies, indicating a positive trend in dose optimization. This study emphasizes the importance of regular dose audits and patient dose awareness. Educating patients on radiation risks and optimizing radiographic techniques are essential for minimizing unnecessary exposure while maintaining high diagnostic image quality.

沙特一家三级医院普通数字放射照相过程中患者辐射暴露评估

这项研究是对在Majmaah的哈立德国王医院（KKH）接受诊断性x射线检查的病人进行的。调查的重点是7种最常用的放射照相程序，包括使用数字放射照相（DR）设备检查的1,504例患者。使用测量的x射线管输出和照射参数，通过计算入口表面空气克尔玛（ESAK）和有效剂量（ED）来评估患者的辐射剂量。根据这些测量结果，应用了适当的转换系数。本研究还分析了ESAK和Kerma面积产品（KAP）的第75百分位分布，并将结果与国家和国际剂量参考水平进行了比较。本文给出了计算的不确定性(U)值以及ESAK、KAP和ED的平均值。ESAK值为0.12 ~ 5.74 mGy， KAP值为0.9 ~ 1.84 Gy·cm2， ED值为0.01 ~ 0.23 mSv。这些数值明显低于欧洲和各国研究报告的诊断参考水平（DRLs），表明剂量优化呈积极趋势。这项研究强调了定期剂量审计和患者剂量意识的重要性。对患者进行辐射风险教育和优化放射成像技术对于尽量减少不必要的照射，同时保持高诊断图像质量至关重要。

期刊介绍： Radiation Physics and Chemistry is a multidisciplinary journal that provides a medium for publication of substantial and original papers, reviews, and short communications which focus on research and developments involving ionizing radiation in radiation physics, radiation chemistry and radiation processing. The journal aims to publish papers with significance to an international audience, containing substantial novelty and scientific impact. The Editors reserve the rights to reject, with or without external review, papers that do not meet these criteria. This could include papers that are very similar to previous publications, only with changed target substrates, employed materials, analyzed sites and experimental methods, report results without presenting new insights and/or hypothesis testing, or do not focus on the radiation effects.
