Gamma-Irradiation-EnhancedReduction of 99Tc(VII) and Re(VII) by Natural Pyrite

Abstract Reductive immobilization of 99Tc(VII) to sparingly soluble TcO2-type phases is a key process limiting 99Tc transport in the environment. However, the reactivity of natural pyrite toward 99Tc(VII) under conditions relevant to nuclear waste repositories remains poorly unde...
