Abstract: The volume activity of 3H, 90Sr, 137Cs, 234U, 235U, 238U, 238Pu, 239+240Pu, and 241Am in ground waters from observation holes 1-G-6-G in the north section of the Shelter local area of the Chernobyl Nuclear Power Plant (CNPP) was measured. The distribution of radionuclides in the suspension fractions of the ground waters was evaluated. The main contribution to the pollution of ground waters with uranium is due to natural uranium isotopes: 234,235,238U. The activity ratios of 238Pu, 239+240Pu, and 241Am in ground waters are similar to those in the spent fuel of 4th CNPP block.

Abstract:The studies of 137Cs and 90Sr accumulation characteristics by birch wood (Betula pendula Roth.) growing in different edaphic conditions. Describes the increase in soil fertility from trophotops A to D results in 5-fold 137Cs transfer factor decrease and 2-fold decrease of 90Sr. Soil humidity increase for each grade of trophic net results in the increase of 137Cs transfer factors to wood and decrease for 90Sr. Total activity of 137Cs and 90Sr in birch wood plantation depends on productivity of plantation and on radionuclide transfer factors depending on different plantation conditions. In the most prevailing edaphotops (B2, ВЗ, С2 and C3) birch wood accumulates 0.6-1.2% of 137Cs and 13-19% of 90Sr from total activity of radionuclides in biogeocenosis.

Title: Characteristics of Chernobyl-derived radionuclides in particulate form in surface waters in the exclusion zone around the Chernobyl Nuclear Power Plant

Keywords: Chernobyl; Transuranic elements; Cs-137; Sr-90; Surface water body; Partitioning; Distribution ratio
Abstract: The distribution of Chernobyl-derived radionuclides in river and lake water bodies at 6–40 km from the Chernobyl Nuclear Power Plant was studied. Current levels of radionuclides (Cesium-137, Strontium-90, Plutonium, Americium and Curium isotopes) in water bodies and their relation to the ground contamination are presented. The investigation of the radionuclide composition of aqueous and ground contamination revealed that radionuclides on suspended solids (particulate form) originate mainly from the erosion of the contaminated surface soil layer in the zone. Apparent distribution ratios between particulate and dissolved forms are compared to known distribution coefficients.

Title: Long-term dynamics of radioactive 90Sr and 137Cs contamination of small mammals in the Chernobyl zone

Keywords: small mammals, 137Cs, 90Sr, radionuclide accumulation
Abstract: Between 1986 and 1994, a decrease in nonalimentary 90Sr and 137Cs intake and changes in the accessibility of radionuclides in the soil-plant link of their cycle resulted in a 10-to 100-fold decrease in their specific activity (SA) in the bodies of small mammals inhabiting the Chernobyl zone, and a similar decrease was observed in the radionuclide transition factor (TF) in the soil-animal chain. Between 1995 and 2005, no consistent increase or decrease in SA or TF could be revealed against the background of a combined effect of different physicochemical and ecological factors. It is suggested that subsequent changes in the level of radioactive contamination of small mammals will generally reflect only the dynamics of physical 90Sr and 137Cs decay, but, nevertheless, seasonal and local variations in this level will be significant.
