Abstract

Filtering of ground level air is performed weekly at seven different locations in Sweden: Kiruna, Umeå, Gävle, Ursvik, Grindsjön, Visby and Ljungbyhed. The filters are compressed and the contents of different radionuclides are measured by gamma spectroscopy. Precipitation is also collected at four of the stations: Kiruna, Gävle, Ursvik and Ljungbyhed, the samples are ashed and the contents of radionuclides measured. The level of 7Be and 137Cs in air and deposition are presented for the different stations. Other anthropogenic radionuclides detected, if any, are also presented.
