National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

External Radiation Exposure and Mortality among a Cohort of Uranium Processing Workers.

PB2000106639

Publication Date	1998
Personal Author	Ellis, E. D.; Watkins, J. P.; Ingle, J. N.; Phillips, J. A.
Page Count	28
Abstract	The purpose of the study was to investigate mortality in a cohort of 2514 white males employed in a uranium processing plant between 1942 and 1966 to evaluate: (1) mortality compared to the U.S. population, and (2) the relationship between external ionizing radiation and cancer and other diseases of the respiratory, digesting, genitourinary, and lymphatic systems. Standardized Mortality Ratios (SMRs) were calculated for 56 causes of death. Annual external radiation doses were obtained from individual film badge readings. Poisson trend test statistics were computed using time-dependent cumulative doses. Dose-response estimates with likelihood based confidence intervals (CIs) were calculated using a stratified excess relative risk model.
