摘要
采用历史前瞻性调查方法进行第3次江西E铀矿矿工死因流行病学调查,并对三次的调查结果进行比较。结果表明随着人年数的增加,全死因,全癌及肺癌95%置信区间缩小,在后两次分析中全死因、全癌的标化死亡比(SMR)均低于全国中小城市居民,在非癌类死因中只有死因不明SMR大于1(p<0.05),癌类死因中肺癌SMR大于1(p<0.01)且与氡子体累积暴露量间呈现明显的剂量效应关系。
The third investisafion of the cause of death of the uranium miners in Jiangxi E uranium mine was made with a perspective method. The results of the study were compared with those of the previous two studies. The results show that 95% confidence interval （CI） of all cause of death and all cancer narrowed, and the SMR of all cause of death and all cancer in the last two studies were significantly lower than those for national population. The SMR of unknown cause of death in non-cancer of death and the lung cancer was larger than 1, indicating a statistical difference from the general population. The trend test of lung cancer related to accumulative radon exposure shows positive and the p -value was smaller than 0.01.
