| Abstract:: |
| 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. |
