Abstract

This study assessed the geogenic radon potential using PECAME, an innovative tool designed to simultaneously measure soil-gas permeability and CO\(_2\) concentration — two key parameters for understanding radon transport in soil. Comparative field studies using the RADON-JOK device in various geological settings in Japan and Poland demonstrate the effectiveness of PECAME. These studies reveal a strong correlation between PECAME and RADON-JOK, with an R\(^2\) value of 0.94 for flow rate of 3.5 dm\(^{3}\) min\(^{-1}\). Since the soil-gas Rn concentration and permeability were measured simultaneously, the geogenic radon potential was calculated. Most measured points fall within the low to medium radon index zones, with two exceptions near active faults located in the high zone. Therefore, permeability and CO\(_2\) measurements using PECAME may facilitate further research in Japan to develop a comprehensive geogenic radon potential map.

开发一种同时测量土气渗透性和CO \(_2\)浓度作为地质氡势评价重要参数的新工具

本研究使用PECAME评估了地质氡潜力，PECAME是一种创新的工具，旨在同时测量土壤气体渗透率和CO \(_2\)浓度，这是了解土壤中氡运移的两个关键参数。在日本和波兰的不同地质环境中使用RADON-JOK装置进行的比较实地研究证明了PECAME的有效性。这些研究表明PECAME和氡- jok之间存在很强的相关性，当流量为3.5 dm \(^{3}\) min \(^{-1}\)时，R \(^2\)值为0.94。由于同时测量了土壤气中氡浓度和渗透率，因此计算了地层氡势。大多数测点落在低至中等氡指数带内，有两个例外靠近活动断层位于高区内。因此，利用PECAME测量渗透率和CO \(_2\)可以促进日本进一步研究，以开发综合的地球成因氡势图。
