[Increasing the radon concentration in natural water without the use of radium preparations]. 1994

S V Andreev

The method of increasing radon concentrations in natural radon water without radon generators is based on radon redistribution between various water volumes, water and air. Radon is extracted from hot radon water with subsequent solution in cold radon water. This method enables the specialists to increase radon concentrations 2-3-fold using a simple enriching unit.
