| Estimating historical radiation doses to a cohort of U.S. radiologic technologists
(2006
) | | | This paper describes our early efforts to reconstruct occupational radiation doses among the 90,000 radiologic technologists who completed the baseline survey during the mid-1980s. The dose estimation used available film badge measurements (approximately 350,000) for individual cohort members, information provided by technologists about their work history and protection practices, and measurement and other data from the literature. Dosimetry models estimated annual and cumulative occupational badge doses for each technologist for each year worked from 1916 to 1984, plus absorbed doses to organs and tissues, including bone marrow, breast, thyroid, ovary, testes, lung, and skin.

(2004
) | | | Data and physical/statistical models were used to estimate unknown occupational radiation doses to 90,000 members of the U.S. Radiological Technologists cohort who responded to the first major questionnaire conducted in the mid-1980s. The dosimetry estimation used available film-badge measurements (approximately 350,000) for individual cohort members, technologist’s responses on their work history/protection practices, and data from published literature. The complete dosimetry model estimates annual and cumulative occupational badge doses (personal dose equivalent) for each technologist for each year worked from 1916 through 1984, as well as absorbed doses to organs and tissues including bone-marrow, female breast, thyroid, ovary, testes, lung and skin. Workers who began work prior to 1950 had significantly higher doses than those first working in later years.
