主动瞬时活性炭吸附土壤氡气测量方法初探

Research of Active Activated Carbon Adsorption Measurement for Soil Radon and Its Application

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 adsorp- tion method was studied at first, And then, the factors affecting the activated carbon adsorption capaci- ty, 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 com- pared. Compared to the traditional activated carbon accumulation passive radon measurement, this meth- od greatly improved the working efficiency, and laid foundation for further environmental monitoring, exploration and prospecting.
