Microbial communities have the potential to control the biogeochemical fate of priority radionuclides in contaminated land and also in geodisposal scenarios. However, there have been few studies on the impact of ionizing radiation on microbial communities in sediment systems. In irradiated systems, there was a relative increase in the proportion of bacteria capable of Fe(III)-reduction, with Geothrix fermentans and Geobacter sp. identified in radiation treatment. These results indicate that biogeochemical processes will likely not be restricted by radiation dose rates expected in environments relevant to land contaminated with radioactive waste and geological disposal of nuclear waste. |
