Abstract
Radionuclide contents of surface soil samples, collected shortly after the Chernobyl fallout, are reported. The samples are from the area of wet-deposition (with the highest fallout), from Uppsala in the south to Kramfors in the north. Although showing extensive variations, a general trend of characteristic isotopes can be deduced, viz. 137Cs along the coast of southern Norrland, followed by a zone characterized by 131I to the north and south, and, finally, by a zone with predominant 132Te. Several radionuclides, such as 95Nb, 95Zr and 141Ce, define an independent, irregular pattern. Europium isotopes have been found along the coast of southern Norrland only. Five analyses of 90Sr indicate that extensive variations in the abundance of this isotope relative to 137Cs occur.
