This paper presents the results of measurements of 137Cs in soil profiles which were sampled in the Chechło and Zalesie areas, on the Proboszczowicka Highland, Poland, May 2002. Samples were collected from four soil profiles, three of them were taken on the cultivated field and one on the undisturbed field. The vertical distribution of 137Cs in collected profiles and the 137Cs inventory for all locations have been determined. The pH of soils (in distilled H2O and KCl solution) and the organic matter content of soil samples were also measured. Caesium concentration ranged from 0.0 to 15.37 Bq/kg and from 0.0 to 101.61 Bq/kg in soils from cultivated and undisturbed sites, respectively. The measured 137Cs deposition has been compared with the nuclear weapon tests caesium fallout. The obtained results show that the Chernobyl 137Cs fallout had relatively large contribution to total 137Cs deposition in the study areas.
