XXXX incidence in the US radiologic technologists health study, 1983-1998.

@entity1 @entity0 @entity4093 @entity5 @entity2 @entity259 @entity320
BACKGROUND: Workers exposed to low doses of radiation can provide information regarding @entity5 risks that are of public concern. However, characterizing risk at low doses requires large populations and ideally should include a large proportion of @entity1 , both of which rarely are available. METHODS: Among 90305 radiologic technologists in the U.S. (77% @entity1 ) who were followed during 1983-1998, data concerning incident @entity5 occurrence was obtained from mailed questionnaires and from death records. Standardized incidence ratios (SIRs) were computed using age-specific, gender-specific, race-specific, and calendar year-specific @entity5 rates from the Surveillance, Epidemiology, and End Results Program. RESULTS: The SIR for all @entity5 in both genders combined was 1.04 (95% confidence interval [95% CI], 1.00-1.07; n = 3292 technologists). Female technologists had an elevated risk for all solid @entity5 combined (SIR = 1.06; 95% CI, 1.02-1.10; n = 2168 @entity1 ) and for @entity0 (SIR = 1.16; 95% CI, 1.09-1.23; n = 970 @entity1 ), @entity320 (SIR = 1.66; 95% CI, 1.43-1.89; n = 181 @entity1 ), and @entity259 (SIR = 1.54; 95% CI, 1.24-1.83; n = 107 @entity1 ). Male technologists experienced a decreased risk for solid @entity5 (SIR = 0.92; 95% CI, 0.85-0.98; n = 755 @entity1 ); however, @entity320 (SIR = 1.39; 95% CI, 1.00-1.79; n = 56 @entity1 ) and @entity259 ( @entity4093 .23; 95% CI, 1.29-3.59; n = 17 @entity1 ) were increased. Among both genders, the risks were decreased for buccal cavity/ @entity5 (SIR = 0.73; 95% CI, 0.55-0.90; n = 54 technologists), @entity5 (SIR = 0.62; 95% CI 0.48-0.76; n = 53 technologists), and @entity2 (SIR = 0.77, 95% CI, 0.70-0.85; n = 307 technologists). CONCLUSIONS: The elevated risk for @entity0 may have been related to occupational radiation exposure. The observed excesses of @entity320 and @entity259 may reflect, at least in part, earlier detection among medical workers with easy access to health care.
