本文应用回顾性队列研究方法,调查了中国长城铝业公司职工癌症死亡率,结果发现铝冶炼业职工癌标化死亡率为101.53/10万,居各种疾病死亡率的第一位。其中肺癌标化死亡率为29.25/10万,居各部位癌死亡率之首位,而且明显高于非冶炼业职工和所在区居民的死亡水平,其原因可能与生产环境中放射性氡污染有关。
In this paper, a retrospective cohort study was conducted to investigate the cancer death rate of the employees of China Great Wall Aluminum Corporation. The results showed that the cancer-standardized death rate of workers in the aluminum smelting industry was 101.53 / 100,000, ranking the first among all kinds of disease deaths. Among them, the standardized death rate of lung cancer was 29.25 / 100,000, ranking the first among all cancer deaths and significantly higher than the death rate of non-smelting workers and residents in the area where the cause may be related to radioactive radon pollution in production environment .
