铀矿电离辐射白内障四例报告

Four cases of ionizing radiational cataract in a uranium mine

本文报告4例电离辐射白内障,全部是从事井下4大工种骨干工人;专业工龄19～20年,年龄38～53岁,辐射剂量分别为α50.10—94.00 γ6.66—16.36,HE57.60—110.36Rem,排除了接触白内障的因素与疾病;发病原因是长期低剂量的电离辐射直接作用于晶体。建议铀矿工人应当穿戴防护工作服和铅防护眼镜,以及采用轮换作业等防护措施。

Four cases of cataracts by ionizing radiation werereported. They worked in the pit bottom and are main-stay. Their length of service: 19～20. years. age:38～53years old. radiation dose: α 50.10 ～ 94.00 Rem., γ6.66～ 16.36 Rem. HE 57.60～ 110.36 Rem. Therewere no other causes and diseases, and the main causewhich cause was that low-dose ionizing radia-tion for-long time directly affects on the lens. It issugested that the miners in uranium mine must wearprotecting work clothes and glasses and take rariousmeasures such as work in turn etc.
