摘要
通过综合分析研究黔东松桃-黄平地区上震旦统-下寒武统留茶坡组地层γ辐射测量、土壤氡气测量和天然放射性元素含量等资料,调查本区放射性水平。结果表明:研究区留茶坡组地层岩矿样、土壤样和拣矿样中放射性核素^(238)U、^(232)Th、^(226)Ra、^(40)K与贵州省土壤放射性核素背景值、我国土壤放射性核素背景值对比绝大多数均较低。通过单因子指数法对研究区放射性水平污染情况进行评价,绝大多数为无污染区,极少部分为重度污染。据水样中放射性水平与我国自来水标准相比较,多数低于我国自来水标准。
The radioactivity of Liuchapo group of Upper Sinian-Lower Cambrian in Songtao-Huangping in the eastern Guizhou is refected through the comprehension research of the γ radiation measurement, the soil radon measurement and the natural radioactivity elements. The results refect that most of the natural radioactivity elements ( 238U、232Th、226Ra、40K) of the rock or mineral sample of the Liuchapo group, the soil sample and the pickup sample are low which relative to the soil radioactivity elements background value of Guizhou and our country. The radioactive pollution level in the study area is evaluated through the single factor index method, the results refect that the most area is no pollution and less area is serious pollution area. According to the sample of radioactive level compared with tap water standard in our country, most areas are less than tap water standard.
