Abstract The aim of the study was to evaluate the radiation entrance skin dose (ESD) in most radiographic X-ray examinations in Taif City, Saudi Arabia. The study was carried out in 3 different hospitals in Taif City. These hospitals are indicated in this study as I, II, and III. In total, 221 images were acquired at the aforementioned hospitals by using two different techniques of dose assessment, DosCal software and the routine thermo-luminescence (TL) method. A data collection sheet was designed to record technical factors (kVp and mAs) and patient bio-data. The average of ESD for all examinations was 1.67 mGy for both methods, while the average tube voltage was 64.6 kVp. Additionally, the highest ESDs were associated with the examination of the lumbosacral and pelvis to be 7.4 and 6.3 mGy, respectively. The two methods of dose assessment were compared and a correlation coefficient of R2 = 0.93 was found. Although this study concluded that, the ESDs obtained in all examinations were lower than those mentioned in the previous studies, more studies in radiation dose field are required to establish a local diagnostic reference level.

沙特阿拉伯常规放射照相检查中患者辐射剂量的评估

摘要 本研究的目的是评估沙特阿拉伯塔伊夫市大多数 X 射线检查中的辐射入口皮肤剂量 (ESD)。该研究在塔伊夫市的 3 家不同医院进行。这些医院在本研究中表示为 I、II 和 III。通过使用两种不同的剂量评估技术、DosCal 软件和常规热发光 (TL) 方法，在上述医院总共采集了 221 张图像。数据收集表旨在记录技术因素（kVp 和 mAs）和患者生物数据。两种方法的所有检查的 ESD 平均值为 1.67 mGy，而平均管电压为 64.6 kVp。此外，最高 ESD 与腰骶部和骨盆检查相关，分别为 7.4 和 6.3 mGy。比较了两种剂量评估方法，发现相关系数为 R2 = 0.93。尽管本研究得出的结论是，所有检查中获得的 ESD 均低于以往研究中提到的 ESD，但仍需要对辐射剂量场进行更多研究，以建立局部诊断参考水平。
