The content of technogenic radionuclide tritium in surface water of peaceful underground nuclear explosion «Crystall» site is considered. The volumic activity of tritium in surface water of the explosion well reaches 12 Bq/l in 2018. It is 630 times less than the intervention limit of drinking water (7600 Bq/kg) according to radiation safety standards. At once it is in 5,5 times higher than the regional background level of tritium activity in river water (in the order of 2,2 Bq/l). The work is done with the help of liquid-scintillation spectrometry on state assignment of IGM SB RAS and on the project No. 18-45-140020 «Features of nuclear technogenesis by the example of the object of the peaceful underground nuclear explosion «Crystal» supported by the Russian foundation for basic research (RFBR).
