The 15-Country Collaborative Study of Cancer Risk among Radiation Workers in the Nuclear Industry: Estimates of Radiation-Related Cancer Risks
2007
International audience; A 15-Country collaborative cohort study was conducted to provide direct estimates of cancer risk following protracted low doses of ionizing radiation. Analyses included 407,391 nuclear industry workers monitored individually for external radiation and 5.2 million person-years of follow-up. A significant association was seen between radiation dose and all-cause mortality [excess relative risk (ERR) 0.42 per Sv, 90% CI 0.07, 0.79; 18,993 deaths]. This was mainly attributable to a dose-related increase in all cancer mortality (ERR/Sv 0.97, 90% CI 0.28, 1.77; 5233 deaths). Among 31 specific types of malignancies studied, a significant association was found for lung cance…

Exposure to video display terminals and risk of small-for-gestational-age birth
2010
In this study, the authors analyzed the association between video display terminal (VDT) use before and during the three trimesters of pregnancy and risk of small-for-gestational-age (SGA) birth in a case-control study. The cases for this study were 555 women who delivered SGA births. The controls were 1966 women who gave birth at term to healthy infants of normal weight. In terms of the length of exposure, the odds ratios (OR) of SGA birth were 1.2 for less than one hour and 1.3 for between two and 20 hours per week. For higher usage (more than 20 hours per week), the OR was 1.2 (95% CI: [Confidence Interval] 0.9-1.7). The authors conclude that this study does not show any association betw…
