Opis:: The paper presents results of the measurements of Pu and gamma emitters of some forest litter/soil profiles collected in 1999 in the northeastern part of Bory Tucholskie forest (northern Poland). Besides the activity concentration of 137Cs, 134Cs, 40K, 228Ac, 238Pu, 239+240Pu, the cumulated deposition of 137Cs, 238Pu and 239+240Pu were calculated. The origin of these radionuclides is discussed on the basis of the observed activity ratios. The observed average level of radioactive contamination confirms expectations for this region, however samples show a relatively large variation of cumulated deposition for both plutonium and radiocesium originated from global and Chernobyl fallout.

Opis:: The present article contains information about the activities and origin of 137Cs, 238Pu and 239+240Pu in the North-eastern Poland. Analyzed samples were collected in 59 locations where forest litter A0 and humus A1 were collected in 1991. An approximate map of the Chernobyl fallout component 239+240Pu was prepared on the basis of received results. The largest Chernobyl 239+240Pu contamination occurred in north-eastern and eastern part of the investigated area, reaching 22.1š1.6 Bqźm–2.

Opis:: This paper presents results of application of a sequential radiochemical procedure for multi-elemental analyses for samples collected in the Arctic environment. The levels of activity of 238Pu, 239+240Pu, 241Am, 90Sr and the content of natural radioisotopes (238U, 234U and 232Th, 230Th) were investigated in soils and peats in the proglacial zone of the Werenskiold glacier and on the strandflat in the vicinity of the glacier. Results on activity concentration shows general low level of radioactive contamination. Procedure was checked using reference materials. Reasonable recoveries were obtained for almost all analyzed radionuclides except for uranium. Further work is needed to improve this stage.
