This work deals with the evaluation of radiation doses from chest x rays for 240 male and female pediatric patients selected randomly from four Palestinian hospitals. The patient population was divided into five age groups: Newborn, 1, 5, 10, and 15 y old. Doses were theoretically calculated by using Monte Carlo based codes: CALDOSE-X5 and PCXMC-2.0. Patients' data and type of radiographic systems used as well as exposure factors were provided by the administrations of the selected hospitals. Absorbed organ doses from AP and PA projections were evaluated for 76 pediatric patients selected from one hospital in East Jerusalem. The highest mean organ dose for these patients was 0.085 mGy to the breast in AP projection. Effective doses were estimated for the five age groups for all patients. The highest average effective dose was found for patients in the age group of 10 y and was about 0.13 mSv, while the lowest average effective dose was found for the 5-y age group, about 0.06 mSv. The mean effective dose for all investigated patients in the five age categories was about 0.08 mSv. Variations in effective doses for the same age group and x-ray examination among involved hospitals are remarkable.

接受常规胸部 X 射线检查的儿科患者的辐射剂量评估。

这项工作涉及从四家巴勒斯坦医院随机挑选的 240 名男性和女性儿科患者的胸部 X 光辐射剂量评估。患者群体分为五个年龄组:新生儿、1、5、10 和 15 岁。使用基于蒙特卡罗的代码从理论上计算剂量:CALDOSE-X5 和 PCXMC-2.0。患者的数据和所使用的放射线照相系统的类型以及暴露因素由所选医院的管理部门提供。对从东耶路撒冷一家医院选出的 76 名儿科患者根据 AP 和 PA 预测吸收的器官剂量进行了评估。在 AP 投影中,这些患者的最高平均器官剂量为乳房 0.085 mGy。对所有患者的五个年龄组的有效剂量进行了估计。10岁年龄组患者平均有效剂量最高,约为0.13 mSv,5岁年龄组患者平均有效剂量最低,约为0.06 mSv。五个年龄段的所有受调查患者的平均有效剂量约为 0.08 mSv。参与医院之间同一年龄组和X线检查的有效剂量差异显着。
