| 摘 要： | 通过对大渡河下游地区地下水放射性环境水平状况的调查，得出大渡河下游地区地下水环境放射性水平处于国家限值范围内，U含量在0．16μg·L^-1．74μgL^-1，Th含量水平极低，IKa在（1．016Bq-L^-10．031Bq·L^-1之间。通过分析，地下水水位的变化受河流水位变化影响较大。

| Abstract: | The investigation of natural radioactivity in water environment in the lower reaches of the Dadu River shows that the radioactive level of groundwater in this region is safe with U of0.16μg·L^-1 - 1.74μg·L^-1, low Th and Ra of less than 0.016Bq·L^-1 - 0.031Bq·L^-1. Water level of groundwater changes with water level of the Dadu River. |
