Abstract
85Kr concentrations observed in ground level air of Prague between 1983 and 1988 are presented and their time-related changes analyzed. The constant long-term trend in the activity level of85Kr with the mean value of /0.84±0.02/0.95 Bq.m−3/STP/ has been found during the investigated period. The recorded short-term fluctuations of85Kr data ranging from 0.61 to 1.10 Bq.m−3 /STP/ were found to be seasonally dependent with pronounced maximum of its concentration occurring in spring. The parameters for the description of85Kr seasonal variations are determined and the obtained results discussed.
