As a result of nuclear explosions, a large amount of uncontrolled radioactive waste was formed in the subsurface of oil and gas fields. The main channels of migration of radioactive waste into water-bearing complexes and to the day surface are presented and it is shown that the cavities formed as a result of nuclear explosions are highly permeable. Nuclear explosions carried out in salts have broken the tightness of the cover of gas condensate deposits. Measures to organize geo-ecological safety of nuclear facilities are proposed.
