|
摘要
研究了主动式活性炭吸附土壤氡气测量方法。在氡室条件下,利用设计的取样装置对主动式活性炭吸附法中活性炭吸附能力、取样量、取样速度等影响因素及测量参数开展了实验研究,并进行了该方法与其他3种不同土壤氡气测量方法的野外对比实验,相对于传统的被动式活性炭累积测氡,该方法工作效率高,为土壤氡气测量在勘探找矿、环境监测等领域的应用提供了一种全新的测量方式。
Based on the overview of soil radon measurement methods,the active activated carbon adsorption method was studied at first,And then,the factors affecting the activated carbon adsorption capacity,adsorption speed,adsorption time of the sample was tested in radon chamber,the experiments of four different instruments using the parameters from radon chamber test were finished and compared.Compared to the traditional activated carbon accumulation passive radon measurement,this method greatly improved the working efficiency,and laid foundation for further environmental monitoring,exploration and prospecting.
