国内外大量的流行病学调查证实:职业性肺癌的发生与氡及其子体的积累暴露量有关。对于非放射性矿山氡及其子体引起的职业性肺癌尚未引起足够的重视,部分矿山通风条件较差,防尘降氡措施不力,因而在某些非放射性矿山井下作业场所中有可能存在较高浓度的氡及其子体。氡和氡子体潜能的测定,分别采用曾达成和马尔科夫法对我省大都已进入深部采掘的矿山进行了监测。根据各矿的采掘特点及通风状
A large number of epidemiological studies at home and abroad confirmed: the occurrence of occupational lung cancer and radon and its progeny accumulated exposure related. Occupational lung cancer caused by radon and its daughters in non-radioactive mines has not yet received sufficient attention. Some mines have poor ventilation and poor dust-proof and radon-lowering measures. Therefore, it is possible that there may be a higher level of workplaces in some non-radioactive mine wells Concentration of radon and its daughters. The determination of radon and radon progeny potential, respectively, have been achieved and the Markov method for the majority of our province has entered the deep mining of mines were monitored. According to the mining characteristics and ventilation of the mine
