A cohort mortality study of lung cancer in 7088 copper miners was made from 1 January 1969 to 31 December 1988. There was an excess of deaths from lung cancer in the copper miners. The standardised mortality ratio (SMR) was 147 (p < 0.01). The SMR increased with calendar period. There was a higher risk of deaths from lung cancer in the miners employed in the 1950s. Age at the start of exposure had no effect on the risk of lung cancer. The risk of death from lung cancer increased with the duration of exposure and the time since first exposure. The SMR for lung cancer was 173 in underground miners and 193 for drilling miners (both p < 0.01). These data show that exposure to dust is associated with an excess of deaths from lung cancer in copper miners whereas exposure to radiation does not seem to carry such risk.
1969年1月1日至1988年12月31日期间，对7088名铜矿工人进行了肺癌队列死亡率研究。铜矿工人中肺癌死亡人数过多。标准化死亡率（SMR）为147（p<0.01）。SMR随日历时间增加。20世纪50年代受雇的矿工患肺癌死亡风险更高。开始接触时的年龄对患肺癌风险没有影响。肺癌死亡风险随接触时间和首次接触后的时间增加而增加。地下矿工的肺癌SMR为173，钻孔矿工为193（均p<0.01）。这些数据表明，接触粉尘与铜矿工人肺癌死亡人数过多有关，而接触辐射似乎没有这种风险。
