Monitoring of krypton-85 activity in the atmosphere around Prague

The results of measurements of Krypton-85 ((85)Kr) concentrations in the ground-level air of Prague between 1983 and 1992 are presented and time-related changes analysed. The long-term trend in activity level of (85)Kr has been steadily increasing with a growth rate of 0.04 Bq.m(-3) (STP) per year....

Description
Summary:The results of measurements of Krypton-85 ((85)Kr) concentrations in the ground-level air of Prague between 1983 and 1992 are presented and time-related changes analysed. The long-term trend in activity level of (85)Kr has been steadily increasing with a growth rate of 0.04 Bq.m(-3) (STP) per year. Some peaks of (85)Kr activity were observed due to the influence of undispersed radioactive plumes coming from distant sources. Short-term variations within a typical range of concentrations from 0.61 to 1.25 Bq.m(-3) (STP) were found to be seasonally dependent, with the maximum occurring in spring.
