The Effect of Grain Size on Porewater Radiolysis

The Effect of Grain Size on Porewater Radiolysis

Abstract The radiolysis of porewaters by uranium, thorium, and potassium in mineral grains is a recognized source of molecular hydrogen in rock‐hosted and sediment‐hosted fluids. This radiolytic hydrogen is of geomicrobiological interest as a potential energy source (electron donor) for microbial me...
