Dikaryev O. The peculiarities of Tritium migration in zone of intensive water exchange (on example of Kyiv radioactive waste storage facility).

The tritium migrations' peculiarities in atmosphere, zone of intense water exchange, ground waters and distribution in forest ecosystem was estimated. Tritium's deposits in zone of active water's exchange on the territory of the Kyiv radioactive waste storage facility was calculated. The radiohydrogeochemical tritium anomaly's evolution phases analysis has been carried out. The radiohydrogeochemical tritium anomaly's formation retrospective analysis has been done. The tritium's distribution in ground profile and woods vertical structure has been researched. The tritium deposits' in form of free tissue water of wood and ground layers of aerated zone has been valuated. The tritium's emission in course of Kyiv radioactive waste storage facility became 0,5 % of waste storage content: atmospheric release - 0,21 %, in underground water підземні води - 0,21 %, deposit in aerated zone to underground water's level - 0,016 %, in ecosystems - 0,004 %. Recommendation for new Tritium standards in Ukraine has been formulated.
