Abstract

Soil samples from Paraná State, Brazil, were collected in 1991 and compared with others collected at the same location in March 1977 and at the end of 1983. Pedological analyses were practiced on these samples and137Cs and232Th,226Ra and40K activities were determined by gammaray spectrometry. A latitude dependence of137Cs was found as well. It was impossible to determine the137Cs contribution from Chernobyl nuclear accident because of low fallout and intense leaching, erosion and re-suspension in soils of regions with high annual precipitation. Natural radionuclides did not show such effects.
