Abstract
In order to evaluate the possibility of radiation-induced wall-rock he matitization of moderate low temperature hydrothermal uranium deposits , simulating experiments on the radiation-induced oxidation of ferrous iron with gamma-rays have been conducted in aqueous solutions at 25 a nd 200 degrees C. The results show that the groundwater radiolysis is capable of oxidizing ferrous to ferric iron which will subsequently pr ecipitate as iron oxy-hydroxides.
