Abstract

Filtering of ground level air is performed weekly at seven different locations in Sweden: Kiruna, UmeA, Gc~vie, Ursvik, Grindsjdn, 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, Gdvie, Ursvik and Ljungbyhed, the samples are ashed and the contents of radionuclides measured. The levels of 7 Be and 137CS in air and deposition are presented for the different stations. Other anthropogenic radionuclides detected, if any, are also presented.
