目的在核工业职工全死因调查的基础上，着重进行死因危险及相关职业危害的分析，探讨职业与健康的关系。方法调查对象为１１个单位自组建至１９９０年底在册职工，分组观察。调查历年职工人数及死亡资料，按ＩＣＤ－９原则进行死因统计。结果粗死亡率１９３．６６×１０－５，标化死亡率２３７．６５×１０－５，而放射组、非放射组分别为３４６．１１×１０－５、２０２．０３×１０－５（Ｐ＜０．０１），但均低于全国值。放射组与非放射组比较，ＲＲ１．７０（Ｐ＜０．０１），但去除矽肺和工伤死亡，ＲＲ１．３０（Ｐ＞０．０５）。肿瘤居死因之首，第二为损伤与中毒。全死因ＳＭＲ０．４６，肿瘤０．７６，而损伤与中毒１．２０（Ｐ＜０．０１）；肺癌１．４０（Ｐ＜０．０１）；脑瘤１．５１（Ｐ＜０．０５）；铀矿系统肺癌、脑瘤、胃癌、肝癌、白血病增加明显。结论与死亡相关的职业危害为粉尘、工业外伤和氡子体，放射组死因危险因此增高，但情况在不断变化。男性比女性有更多死因危险，铀矿工肺癌与氡子体暴露有关。
Objective Based on the investigation of all causes of death in the nuclear industry, the author focuses on the analysis of the risk of death and related occupational hazards and discusses the relationship between occupations and health. Methods The survey was conducted in 11 units registered self-established by the end of 1990, with group observation. Investigate the number of workers and death records over the years, according to ICD-9 principle of cause of death statistics. Results The crude mortality rate was 193.66 × 10-5, and the normalized mortality rate was 237.65 × 10-5. The radiotherapy group and non-radiation group were 346.11 × 10-5 and 202.03 × 10-5, respectively <0.01), but lower than the national average. RR1.70 (P <0.01), but the deaths from silicosis and injuries, RR1.30 (P> 0.05). The first cause of death in cancer, the second is injury and poisoning. All-cause SMR 0.46, Tumor 0.76, and injury and poisoning 1.20 (P <0.01); Lung cancer 1.40 (P <0.01); Brain tumor 1.51 (P <0.05) ; Uranium system lung cancer, brain tumor, stomach cancer, liver cancer, leukemia increased significantly. Conclusions Occupational hazards associated with death are dust, industrial trauma and radon progeny, which in turn increases the risk of death from radiation groups, but the situation is constantly changing. Men have more death causes than females, and uranium miners lung cancer is associated with exposure to radon progeny.
