Abstract In ground-level air the fission product activity originating from nuclear weapon tests varies with time, both in intensity and composition. The variations were mapped using gamma -spectrometric measurements made on monthly ground-level air samples taken near Stockholm, Sweden. This activity variation was correlated with known nuclear weapon tests. The results given cover the period September 1957 to December 1959. The measurements were performed at the end of 1959 and beginning of 1960, and the concentrations of Zr/sup 95/, Sb/sup 125/, Cs/sup 137/, and Ce /sup 144/ were determined. Activities calculated to October 18, 1959 are tabulated. (B.O.G.)
