Natural Radioactive Environments As Sources Of Local Disequilibrium For The Emergence Of Life
Certain subterranean environments of Earth have naturally accumulated long-lived radionuclides, such as 238U, 232Th and 40K, near the presence of liquid water. In these natural radioactive environments (NRE), water radiolysis […]
