  Measurement results are presented on 85Kr content in the atmosphere over the
European part of Russia in 1971-1995 based on the analysis of the commercial
krypton, which is separated from air by industrial plants. Our results are by
15 per cent lower then 85Kr activites observed over West Europe. According our
prediction by 2030 85Kr content in the atmosphere over Europe will amount to
1,5-3 Bq in m3 air. Average 85Kr release to the atmosphere from regeneration of
spent nuclear fuel (SNF) is estimated, some 180 TBq per a ton SNF. It is
advisable to recommence monitoring of 85Kr content within Russia.
