Bio - geochemical behavior of 90 Sr and 137 Cs in tropical soil
In this work TF values for Sr and Cs were measured for reference plants grown in lysimeters containing soils representative of large agricultural areas in Brazil: Ferralsol, Nitisol and Acrisol. These results were discussed in the light of pedological analyses and results from the follow sequential chemical extraction protocol: 1) slightly acidic phase containing readily bioavailable elements; ...
متن کاملEstimation of 137 Cs and 90 Sr ionizing radiation impact on the plant vegetative and generative organs
Topicality of the ionizing radiation impact on organisms is conditioned by Nuclear Power Plants (NPP), releasing of various technogenic radionuclides into the environment during the operational period in different in different way. Chronic exposure of low doses of ionizing radiation to biota is an invisible, however, inevitable factor of the environment (Lu et al., 2006; Geras’kin et al., 2007;...
متن کاملThe transfer of (137)Cs, Pu isotopes and (90)Sr to bird, bat and ground-dwelling small mammal species within the Chernobyl exclusion zone.
Protected species are the focus of many radiological environmental assessments. However, the lack of radioecological data for many protected species presents a significant international challenge. Furthermore, there are legislative restrictions on destructive sampling of protected species to obtain such data. Where data are not available, extrapolations are often made from 'similar' species but...
متن کاملThe validation of the dynamic food chain model BURN-POSEIDON on Cs-137 and Sr-90 data of the Dnieper-Bug estuary, Ukraine
The uptake of radioceasium and radiostrontium in biota in dose assessment models is mostly estimated on the basis of Concentration Factors (CF). For accidental releases, the dynamical foodweb model BURN has been implemented in the coastal model POSEIDON (part of the Decision Support System RODOS). BURN can be applied on water bodies with different salinity levels, since in the model the uptake ...
متن کاملChronic Cs-137 incorporation in children's organs.
In Belarus's Gomel region, which was heavily contaminated by fallout from the Chernobyl disaster, we have studied the evolution of the Cs-137 load in the organisms of the rural population, in particular children, since 1990. Children have a higher average burden of Cs-137 compared with that of adults living in the same community. We measured the Cs-137 levels in organs examined at autopsy. The ...
