“…The ratio between 239C240 Pu and 241 Am activities for S 5 sample of 0:224 G 0:044 is somewhat lower than the global fallout ratio of about 0.3 (UNSCEAR, 1993) and significantly lower than the present Chernobyl ratio of about 1.5. Such ratio for Chernobyl fallout can be calculated including americium ingrown from 241 Pu decay (Kudryashov et al, 2001). Our result suggests that americium is transferred or accumulated in bones perhaps less effectively than plutonium, possibly due to a shorter biological half-life time of Am.…”

“…Some kind of verification of the possible impact of Chernobyl fallout in investigated samples can be done by an analysis of 241 Am/ 239+240 Pu ratios. For the global fallout this ratio equals roughly 0.4, while for Chernobyl fallout is much higher, finally close to 3:1 [ 25 ]. In particular, elevated values of isotopic ratios were found in the upper layer of profile 1 and 6 and in the lower layers of the profile 10.…”

The paper summarizes results of investigation of the current state of radioactive contamination on site being under consideration for planned nuclear power plant in northern Poland. Thanks to use of sequential procedure it was possible to determine activity concentrations for radioisotopes of nine elements, both natural and artificial. Results show that observed levels of radioactive contamination are rather typical for central Europe and global fallout is dominant factor of presence of artificial radionuclides. The total deposition for artificial radionuclides revealed maxima equal to 1747 ± 121 Bq/m2 for 137Cs, 3854 ± 158 Bq/m2 for 90Sr, 101 ± 23 mBq/m2 for 237Np, 57.7 ± 6.0 Bq/m2 for 241Am, 3.27 ± 0.80 Bq/m2 for 238Pu and 68.5 ± 5.0 Bq/m2 for 239+240Pu.

“…Again they are higher for NE areas then for S, where the average is close to the global fallout value for this ratio equal 16 to about 0.3. The present Chernobyl ratio 17 (including 241 Am ingrown from 241 Pu decay) is about 1.5, so it is a much higher value than found in NE samples. The difference in activities ratios between samples from S and NE location, as discussed here, can be seen, but only a possible very weak activity ratio increasing with time tendency for 241 Am to 2391240 Pu was suggested for samples from Białowiez ˙a forest.…”

Adults of the geotrupine beetle Anoplotrupes stercorosus (Coleoptera, Geotrupidae), a common European forest insect species, were used in the role of bio-monitors for mainly man-made radionuclides in a forest environment. Activities of 137Cs, 40K, 238Pu, (239+240)Pu, 90Sr and 241Am were studied. Samples originated from four areas in Poland, two from the north-east and two from the south of the country. The north-eastern areas were previously recognized as the places where hot particle fallout from Chernobyl took place. Results confirmed the differences in the activities between north-eastern and southern locations. Significant correlations were found between activities of 40K and 137Cs, and between activities of plutonium and americium isotopes. An additional study of the concentration of radionuclides within the bodies of beetles showed a general pattern of distribution of radioisotopes in the insect body.
