火山岩型铀矿山环境地质调查评价方法研究

Method Study of Geological Survey and Assessment for Environmental Radioactivity of Volcanic Uranium Mine

通过对典型火山岩型铀矿山及周边地区的环境地质调查及样品分析测试,厘定矿山放射性气态、液态、固态源项特征及分布,开展放射性迁移循环途径研究及矿山周边公众潜在附加剂量评价研究,初步建立放射性矿山环境地质调查评价体系。结果表明,该研究可以为查明火山岩型铀矿山开发过程中对环境介质的影响程度和范围提供方法指导。

Based on a survey into the environmental geological characteristics of typical volcanic uranium mine and the surrounding areas,as well as analyses of samples collected from these investigated sites,this study specified the features and distribution of radioactive gaseous,liquid,solid source in the mine.By researching the radioactive migration and radiation dosage of the residents adjacent to the uranium mine,a framework was established for the geological investigations and evaluations of the environmental radioactivity for volcanic uranium mines which can serve as a methodological guideline for environmental impact assessments of uranium mine exploitation.
