abstract = {Radiocesium and radiostrontium are among the most
problematic soil contaminants following nuclear fallout
dueto their long half-lives and high fission yields. Their
chemical resemblance to potassium, ammonium and
calciumfacilitates their plant uptake and thus enhances
their chance to reach humans through the food-chain
dramatically.The plant uptake of both radionuclides is
affected by the type of soil, the amount of organic matter
and theconcentration of competitive ions.In the present
lysimeter scale experiment, soil-plant transfer of Cs-137
and Sr-90 was investigated in anagricultural silty soil
amended with digestate, a residue from a biogas plant. The
liquid fraction of the digestate,liquor, was used to have
higher nutrient competition. Digestate application was done
in accordance with thefield practice with an application
rate of 34 Mg/ha and mixing it in top 5 cm soil, yielding a
final concentrationof 38 g digestate/Kg soil. The top 5 cm
soil of the non-amended reference soil was also submitted to
the samemixing procedure to account for the physical
disturbance of the top soil layer. Six months after the
amendmentof the soil, the soil contamination was done with
water-soluble chloride salts of both radionuclides,
resulting in acontamination density of 66 MBq/m2 for Cs-137
and 18 MBq/m2 for Sr-90 in separate experiments.Our results
show that digestate application led to a detectable
difference in soil-plant transfer of the
investigatedradionuclides, effect was more pronounced for
Cs-137. A clear difference was observed in plant uptake
ofdifferent plants. Pest plants displayed higher uptake of
both radionuclides compared to wheat. Furthermore,
loweractivity values were recorded in ears compared to stems
for both radionuclides.},
