| 目的 利用归一化工作量的剂量估算方法,估算1980年建立的江苏省医用诊断X射线工作者流行病学队列成员个人剂量计佩戴处的累积皮肤剂量(下面简称剂量),为队列流行病学调查提供剂量依据.方法 收集定群队列成员自参加放射工作至2011年6月间射线接触史资料,结合检查类型和防护条件修正因素,利用Visual Basic编写程序对调查对象进行剂量估算,计算自参加放射工作至2011年6月期间的年剂量.结果 不同时期的平均年剂量有较大差别,1950—1965年为10.1(6.1~12.3) mGy/年,1966—1984年为3.5(2.1~5.4) mGy/年,1985—2011年为1.3(0.9~1.9) mGy/年.结论 本次调查中3 961名医用诊断X射线工作者各时间段的平均年剂量与文献报道数值接近,且变化趋势基本一致. |

| Objective To provide the dose information from the epidemiological cohort established in 1980 in Jiangsu province using normalized workload method, and to estimate cumulative skin dose to medical diagnostic X-ray workers based on personal dosimeter were worn as members of the epidemiological cohort. Methods Data for fixed cohort members of X-ray exposure history from 1950 to June 2011 were collected. According to correction factors such as examination types and protection conditions, exposure doses from 1950s to June of 2011 were estimated through a Visual Basic language program. Results Average annual doses vary significantly between during different time periods: 10.1 (6.1-12.3) mGy/year during 1950—1965, 3.5 (2.1-5.4) mGy/year for 1966—1984 and 1.3 (0.9-1.9) mGy/year during 1985—2011, respectively. Conclusions Average annual doses received by 3 961 medical diagnostic X-ray workers during different time periods in this investigation are nearly consistent with the results reported previously and show a roughly similar trend. |
