Radon Analysis of the correlations between the radon groundwater variations with the strain processes of the rock and transport properties related to the groundwater geochemistry © United States Geological Survey HeRnRa  The emanating power of rocks is defined as the ratio between the amount of radon escaping from the solid matrix and that produced by radioactive decay. Radium decay involves the release of the excess energy which is shared between the  particle which forms (98.1%), and the new radon atom.
