Measurements and Modelling of 137Cs Migration into Various Types of Soil
The behaviour and migration of long-lived radioisotopes is an important part of information in the prediction of the consequences of radioactive contamination in agricultural areas. The soil contamination in Central and Eastern Europe after the Chernobyl accident has been high enough to study the vertical migration of radiocaesium under natural conditions. In the project presented here, the dis...
متن کاملAdsorption of 137Cs on titanate nanostructures
Various types of sodium and potassium titanate nanostructures (nanotubes, nanofibers, nanoribbons, nanwires) were synthesized and characterized by X-ray diffraction, SEM and TEM, as well BET and BJH methods. Adsorption of radiotracer 137Cs+ ions from aqueous solutions on synthesized titanate nanostructures was investigated in batch technique as a function of contact time, concentration of sodiu...
متن کاملMeasurement of 137Cs in soils of Tehran province
Background: An amount of artificial radionuclide has been released into the environment as fallout, resulting from atmospheric nuclear weapon tests, nuclear accidents such as Chernobyl and together with air currents have polluted the world. Materials and Methods: 37 surface soil samples of Tehran province were collected in the period between June and September 2008, by implementing met...
متن کامل137Cs-migration in soils and its transfer to roe deer in an Austrian forest stand.
The depth distribution of 137Cs in an Austrian spruce forest stand was investigated in soil profiles sampled in thin layers (2 cm) and in pooled soil samples over an area of 200 ha. The 137Cs concentrations both from Chernobyl and global fallout decrease exponentially with depth. Forty-six percent of Chernobyl-derived caesium and 26% from global fallout are still to be found in the litter layer...
متن کاملDetermination of 135Cs and 137Cs in environmental samples: A review
Radionuclides of caesium are environmentally important since they are formed as significant high yield fission products (Cs and Cs) and activation products (Cs and Cs) during nuclear fission. They originate from a range of nuclear activities such as weapons testing, nuclear reprocessing and nuclear fuel cycle discharges and nuclear accidents. Whilst Cs, Cs and Cs are routinely measurable at hig...
