Journal Article: Radon As A Tracer For Helium Exploration In Geothermal Areas

Abstract
High heat flow and weak structural features in geothermal areas allow easy passage for release of subsurface gases to the atmosphere. In particular, radon and helium are constantly transported from the earth's interior and vented out through exhalation points in permeable fault zones. At some places unusually large concentrations of helium may be encountered in soil airs. The possibility of trapping the released helium for bulk use has recently emerged. Because of its highly dispersive nature, helium is a difficult gas to detect during field explorations. Radon monitoring is thus taken up to locate structurally weak zones that allow helium permeation. The technique was recently adopted to determine high helium exhalation points in the Birbhum-Santhal Paragana geothermal area.
