A comparison of different detection techniques for 137Cs measurements of cattle in vivo.

Agricultural lands with farm animals (e.g. cattle) can be significantly affected by radioactive contamination following nuclear or radiation accidents.

Ingestion intakes of Cs by the Czech population: Comparison of different approaches.

Ingestion intakes of Cs of the Czech population were calculated in two different ways - either from the measured activity of Cs in components of food in combination with statistical data about consumption rates or from retention of Cs in the human body obtained by whole body counting or calculated from daily urinary excretion of Cs. Data from the time period since 1986 to 2015 are used. The daily ingestion intake was about 25 Bq d in 1986 and is around 0.

Fractionation of (137)Cs and Pu in natural peatland.

High Cs-137 concentrations in plants growing on peatland inspired us to investigate the quantity of its bioavailable fraction in natural peat. Our investigation aims to: a) estimate the quantity of bioavailable Cs-137 and Pu present in peat, b) verify the similarity of Cs-137 and K-40 behaviours, and c) perform a quantification of Cs-137 and Pu transfer from peat to plants. We analysed the vertical distribution of Cs-137 and Pu isotopes in the peat and their concentrations in plants growing on these places.
