宁夏北部地区土壤氡浓度随季节变化规律研究

Research on seasonal variation of soil radon concentration in northern Ningxia

通过对宁夏北部地区土壤氡浓度的测量和分析,发现其受多种因素影响而呈现出季节性变化的规律。其中,地质条件、自然环境和人类活动是影响土壤氡浓度的重要因素。文章提出了一套可行的测量方案,并在春、夏、秋、冬4个季节进行数据采集、处理和分析。结果表明,宁夏北部地区土壤氡浓度在不同季节表现出明显的变化规律,其中夏季土壤氡浓度较高,而冬季最低。

Based on the measurement and analysis of soil radon concentration in the northern part of Ningxia,it is found that it is affected by many factors and presents a seasonal change law.Among them,geological conditions,natural environment and human activities are the important factors affecting the concentration of soil radon.This paper puts forward a feasible measurement scheme,and collects,processes and analyzes the data in spring,summer,autumn and winter.The results show that the concentration of soil radon in the northern part of Ningxia showed obvious variation in different seasons,with the concentration in soil radon being higher in summer and the lowest in winter.
