The transfer of
90Sr to a range of different plant species grown on a range of different soil types in Kazakhstan, including three from the Semipalatinsk Test Site (STS), has been measured in a lysimeter experiment.
90Sr uptake by
Stipa spp was significantly higher than for other vegetation species. The uptake of
90Sr from chernozem was significantly lower than that from the other soil types which is consistent with other literature. There was a significant negative relationship between
90Sr uptake and calcium, humus and CEC concentration in the soil for
Agropyrum spp,
Artemisia spp but not for
Stipa spp or
Bromus spp. The transfer to vegetation from soil has been quantified using the aggregated transfer coefficients for each species. Tag values range from 0.6 to 11.9 m

over all measurements. The transfer of
90Sr to plants from the Kazakh soils was low compared to previously reported data and to that given from literature reviews.
