Radon,Lung Cancer Risk and Environmental Geology in Gejiu Area     

卢伟  王任重等 《中国地球化学学报》1997,16(3):278-282

The incidence of lung cancer in the Gejiu area of Yunnan Province ranks the first in the world.The radon level(indoor,soil) was measured in the Gejiu area by the SSNTD method from 1990 to 1996,The result indicates an extensive high-level of indoor radon in that area though U and Th are lower in local limestones,The indoor radon level of houses located in the geologic fault zone is 6 times high that 2km far from the fault zone.The reason probably is that the radon level of soil in the fault is 6-8 times high that 1 km far from the faults.our data indicate that a lower range of radon levels,0-100Bq.m^-3,exists in healthy families.However,a higher radon level,over 800 Bq.m^-3,is often found corresponding to that of cancer patients‘ homes(the house-owners are suffering from either lung cancer or leukaemia or liver cancer),Obviously,an increase in lung cancer incidence follows an increase in indoor radon level,The risk of cancer induced by indoor radon is no longer an inference,but a fact.  相似文献   

云南个旧松树脚锡矿西部成矿地球化学特征及找矿方向   总被引：3，自引：0，他引：3       下载免费PDF全文

王任重  殷成玉 《地质找矿论丛》1988,(3):1-11

通过对个旧锡矿松树脚矿田不同成矿部位的岩体和矿床的地球化学特征研究,以已知主要矿体分布地段为对比标准,用七类21项地球化学指标对与主要矿体分布地段毗连的普查区作出了成矿地球化学条件评价,这一评价为近来的工程揭露初步证实,并取得了较好的找矿效果。  相似文献   

个旧花岗岩中云母的地球化学特征及其在岩体成矿性评价中的意义     

王任重  殷成玉 《西南矿产地质》1995,9(3):35-42

对个旧花岗岩不同演化阶段及不同成矿性的岩体中的黑云母从矿物化学特征、锡氟协变关系、全岩含锡与黑云母中锡配分比的协变关系、稀土特征等进行了分析探讨，得出了一些对岩体成矿性评价的有意义的信息。  相似文献
