Filtering of ground level air is performed continuously at six different locations in Sweden: Kiruna, Umeå, Gävle, Kista, Visby and Ljungbyhed. The filters are combined and pressed into weekly samples and the contents of different radionuclides are measured by gamma spectroscopy. Precipitation samples are collected at four of the stations: Kiruna, Gävle, Kista and Ljungbyhed. These samples are ashed and the contents of radionuclides are measured monthly. Weekly activity concentrations of 7Be and 137Cs during 2017 in air and precipitation are presented for the different stations. Other anthropogenic radionuclides detected are also presented.
