| Abstract |
Emanometry of Radon on surface of geothermal volcanic areas allows to determine those subsurface zones with low amounts of sealed geological structures. These non sealed fractures behave like conduits of Radon flow which is used as a pathfinder of subsurface geothermal fluids. Radon measurements in surface can be made fastly and easily, to a low cost, using an appropriate sampler and a plastic detector; this can record the tracks of alpha particles which are produced by radioactive decay of Radon. Such a sampling methodology has proved to be useful to measure Radon concentrations in Mexico, at the Los Azufres, Michoacan, geothermal field and at the Las Tres Virgenes, Baja California Sur, geothermal zone, both in volcanic framework. |
