Abstract

The results of monitoring of85Kr volume activity in ground-level air of Prague over the period 1989–1995 are summariyed. Seasonal dependence with a maximum in late spring and summer months and a gradual increase of85Kr concentration in the atmosphere were observed. Linear approximation of long-term trend in the period 1983–1995 gives the growth rate of 35 mBq·m−3 per year. Exponential approximation provides an inter-year growth by 3.7% The measured values were compared to the prognosis of85Kr contamination development of the atmosphere from the early 1980s. They were found to be near to the low estimate of the assumed development.
