sequential radiochemical procedure - 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.
