Mortality Studies - Circulatory System

Mortality from diseases of the circulatory system in radiologic technologists in the United States (2003)
 We found that radiologic technologists have a lower rate of dying from cardiovascular diseases compared to the general U.S. population. But other studies have reported increased mortality in patients treated with radiation. So we examined the risk for all cardiovascular disease mortality by decade of first employment. The decade-first-worked is an indicator of the level of radiation exposure. We found that technologists who began working before 1940 had a 40% greater risk of cardiovascular disease mortality compared to technologists who started working from 1960 or later. The risk of dying from stroke was more than twice as high for technologists who began working before 1940 compared to technologists who began work in 1960 or later.
