ABSTRACT

In order to evaluate the possibility of radiation-induced wall-rock hematitization 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 and 200°C. The results show that the groundwater radiolysis is capable of oxidizing ferrous to ferric iron which will subsequently precipitate as iron oxy-hydroxides.
