本文分析了湖南A铀矿井下氡子体对矿工的危害。早年井下氡和氡子体浓度超过限值20多倍.自建矿至1985年底, 主要工种的氡子体累积暴露量平均200WLM。观察2149名1971年前下井老工人, 1970~1985(15年)肺癌死亡11例, 肺癌粗死亡率35.14×10-5, 特异死亡率24.07×10-5, SMR=3.17。肺癌平均井下工龄18.5年。肺癌绝对危险系数5.58×lO-6人年·wLM-3, 特异相对危险系数5.03×l0-2WLM-1。剂量效应分析表明, 肺癌危硷随氡子体累积暴露量增加而增高。 |

The results of investigation of radon daughters-induced lung cancer in Uranium Ivline A of Hdnan Province are reported. The underground concentrations of 222Rn and radon daughters were higher than DAC in the first 2-3 years.From 1971 to 1985, of 2149 miners who started underground work before 1971, 11 died of lung cancer.The mortality of lung cancer was 35.14×10-5 and the attributable lung cancer rate was 28.28×10-5.The average time period from the start of exposure to death due to lung cancer was 18.5 years.The excess risk rate was 5.58×10-6 WLM-1 a-1 and the relative increment frequency was 5.03×10-2 WLM-1 a-1.The results of epidemiological study indicated that the incidence of lung cancer was increasing along with the increase in cumulative exposure to radon daughters. |
