Abstract

This article focuses on measuring radon (Rn), thoron (Tn), and carbon dioxide (CO₂) concentrations, along with soil permeability, near active geological faults in two distinct regions of Japan with different geological structures. The study found that Rn and Tn levels vary significantly between sites, with one site (TA) showing a marked increase in Rn concentration near the fault, while the other site (UD) did not exhibit such a pattern, likely due to differences in fault type and tectonic activity. Strong correlations were observed between Rn, Tn, and CO₂ concentrations, suggesting that carrier gases like CO₂ facilitate rapid gas migration along faults. The research highlights the influence of geological and tectonic factors on soil gas emissions and plans to expand measurements to additional locations for a more comprehensive understanding.
