摘要
应用前瞻性队列研究方法，对云锡高危人群氡子体致肺癌作用及与其他暴露因素间作用形式进行了探讨。结果表明：调整年龄、粉尘或砷暴露后，随累积氡子体暴露量（ＷＬＭ）增大、暴露年限越长、首次氡子体暴露年龄越小患肺癌的危险性越大。结果支持氡子体是云锡矿工肺癌病因因素的假说。分析没有发现氡子体与吸烟、粉尘、砷暴露、慢性支气管炎史之间有相乘的交互作用。
A prospective cohort study of the high-risk population among miners and smelters in Yunnan Tin Corporation was done from 1992 to the end of 1994. The results showed that the risk of lung cancer increased with accumulated radon decay products(WLM),exposure years of radon,first radon progeny age attained. The study supported that radon progeny is a lung carcinogen among miners in YTC. There is no interactions between radon progeny and smoking,chronic bronchitis,dust exposure,arsenic exposure in the analyses. The patterns of interaction should be evaluated in future.
