Abstract
Novel data are discussed concerning tritium content in surface, ground and underground waters in the area the accidental pacific underground nuclear explosion “Kraton-3” in August 24, 1978. Early studies on the object “Kraton-3” were mainly devoted to the determination of surface contamination in the taiga landscape at the moment of the explosion, and the further redistribution and migration of radionuclides from contaminated areas under the influence of exogenous and biogenic processes. For the first time, an issue was considered whether the underground source of radioactivity is opened. Basing on the analysis of radioecological and geochemical data, a conclusion is drawn that there occurs a significant delivery of radionuclides from the cavity of the explosion to the surface of the earth.
