摘要

Underground explosions cause rock damage affecting fluid and gas transport properties. Understanding this damage is crucial for modeling underground nuclear explosions, but field-scale quantification is challenging. A series of chemical explosive experiments were conducted at Blue Canyon Dome in Socorro, NM, employing several novel measurement and sensing techniques. This study focuses on measurements of radon-222 gas concentration and its evolution post-explosions. Pre-explosion, concentrations showed significant spatial variation, while post-explosion concentrations generally decreased but varied by location. Results indicate that radon concentration alone is insufficient to characterize subsurface rock damage and that single measurements might not represent an average background.
