Alpha spectrometry in radiochemical analysis and its environmental applications

AbstractAlpha spectrometry is a highly sensitive and modern measurement technique which can be used to radiochemical and radiological studies of the natural environment. In the paper were presented the results on application of alpha spectrometry in the study on determination of natural (210Po, 210Pb, 234U, 238U) and artificial (238Pu, 239+240Pu and 241Pu) alpha and beta radionuclides in environment of Poland and Baltic Sea. Amongst the radionuclides, alpha particle emitters play the most important role as they are highly radiotoxic to organisms. The concentrations of alpha radionuclides in the environmental samples of Poland were characterized based on the environmental samples collected between 1998 and 2009. Biogeochemistry of polonium, uranium and plutonium in the southern Baltic Sea ecosystem combined with the use of radioactive disequilibrium 210Po/210Pb, 234U/238U and 238Pu/239+240Pu and 241Pu/239+240Pu allowed to identify the sources of these radionuclides in natural ecosystems, as well as to determine their circulation in the environment (e. g. to assess the impact of the Chernobyl nuclear accident on the radioactive contamination of Poland).
