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 epidemiologicat 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.
