“…Even after 4 years the activity ratio of 241 Am/ 241 Pu is only 1/166. Thus, the lower limit of detection for 241 Pu by direct measurement using a proportional counter is about 10 mBq, whereas via the 241 Am build-up about 200 mBq [17]. The 241 Pu activity can be calculated according to formula [15]: is the account a possible presence of 238 Pu in the sample which alpha energy falls into the same region.…”

Alpha 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 for 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 are characterized based on the environmental materials 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 allows you to identify the sources of these radionuclides in natural ecosystems. It also allows to determine their circulation in the environment (e. g. to assess the impact of the Chernobyl nuclear accident on the radioactive contamination of Poland).

Alpha-spectrometric Pu determinations in aerosol samples collected after the Chernobyl accident in Austria show a 238pu/239 (24~ ratio in the range of 0.33 0.76 with a most reliable value of 0.47. From 241Am measurements in old Pu preparations and air filter analyses also 241pu activities have been calculated. The ratio 241pu/239 (24~ during the main contamination period is 74.6- [-5.7, when maximum 241pu concentrations in air achieved 4.5~.0 mBq/m 3.
