Abstract

The authors evaluated prevalence of aortal atherosclerosis in dependence on radiation and non-radiation factors in workers underwent occupational prolonged irradiation.The study included 22,377 workers of nuclear industry enterprise "Mayak", with verified diagnosis of aortal atherosclerosis. Up to 31th December 2008, a total of 1,840 aortal atherosclerosis cases were registered in the examinees group. Aortal atherosclerosis prevalence appeared to depend reliably on sex, age, smoking habit (in males), alcohol consumption (in males) and arterial hypertension. Findings are that aortal atherosclerosis prevalence was higher in males and females underwent external gamma-irradiation of total dose over 0.5 Gy, in males and females underwent internal alpha-irradiation from incorporated plutonium of total absorbed radiation dose in liver over 0.025 Gy. Thus, aortal atherosclerosis prevalence in workers underwent occupational irradiation de- pended both on radiational and non-radiational factors.

摘要

作者评估了职业性长期受照工人中主动脉粥样硬化的患病率与辐射及非辐射因素的关系。该研究纳入了22377名核工业企业“玛雅克”的工人，他们均被确诊患有主动脉粥样硬化。截至2008年12月31日，受检组共登记了1840例主动脉粥样硬化病例。主动脉粥样硬化的患病率似乎确实取决于性别、年龄、吸烟习惯（男性）、饮酒量（男性）和动脉高血压。研究结果显示，全身总剂量超过0.5 Gy的外照射γ射线的男性和女性，以及肝脏中钚的总吸收辐射剂量超过0.025 Gy的内照射α射线的男性和女性，其主动脉粥样硬化的患病率更高。因此，职业受照工人中主动脉粥样硬化的患病率既取决于辐射因素，也取决于非辐射因素。
