摘要
对青海东部地区34口浅井进行实地调查,使用DDL-1型测氡仪对符合观测条件的26口井中的浅井气氡含量进行了测量,并观测结果进行了初步分析。结果显示,青海东部地区浅井水中氡含量呈现出不均匀分布特征,整体氡含量水平偏低。浅井氡含量与井的深度和温度没有明显的相关性。井水中氡气的含量,应该与井水的来源、流经的通道、井温、矿化度、环境压力等原因有关。此项研究为气氡异常的核实工作积累了背景观测资料。
A field survey was conducted on 34 shallow wells in the eastern region of Qinghai,using a DDL-1 radon meter to measure the gas radon value in shallow wells and to preliminarily analyze the characteristics of changes in gas radon concentration.The results show that the distribution of shallow well gas radon concentration in the eastern region of Qinghai is relatively uniform,and the overall radon content level is relatively low.The radon content in shallow wells in the eastern region of Qinghai shows a positive correlation with the depth and temperature of the wells,and the radon concentration at different depths gradually increases with the increase of well depth.
