A New Laboratory System for the Study of the Effect of Temperature on Radon Transport processes Conference Paper uri icon

abstract

  • The goal of the research is to investigate the mechanisms that control radon temporal changes produced within the geological subsurface media, besides the concentration and pressure gradients within the subsurface lithology that at present are considered the physical driving-forces for radon flow, and specifically to explore the impact of temperature on this mechanism. Lately continuous in-situ field measurements have demonstrated that the ambient temperature at any exposed surface undulates with the daily cycle, with heat waves that last several days and with seasonal (winter and summer) trends producing a changeable temperature gradient at the ground surface, which in turn produces a radon flow within the subsurface media. Following the above-mentioned results, the aim of the new laboratory system is to validate the assumption that time-dependent heating of rock or soil …
