汤阴地堑南部土壤Rn空间分布特征

open access: yesDizhen xuebao, 2022
为分析汤阴地堑南部土壤Rn空间分布特征,揭示其与断裂构造、岩性及沉积层厚度之间的联系,本文采用网格化布点野外流动观测方法测定了该地区380个点的土壤Rn浓度,结果表明:汤阴地堑土壤Rn浓度介于3.09—78.54 kBq/m3,背景均值为27.22 kBq/m3,异常阈值下限为48.40 kBq/m3。在空间分布上,研究区西部(以第四系等厚线50 m为界),受岩石单元和人类石料开采活动的影响,Rn浓度背景值高于东部。在西部高浓度背景影响下,Rn浓度高值异常点除沿汤西断裂带分布外 ...
