Determining the transferfactors for estimates of the radiation contamination of agricultural crops

Popis výsledku v původním jazyce

The study aims to provide a basis for measures reducing the consequences of a nuclear accident in its late phase, when plant contamination occurs mainly through the root system. Samples of the above-ground biomass of crops and soil were taken in 2020 in the vicinity of the Temelín and Dukovany nuclear power plants (Czech Republic). The 137Cs activities were determined using gamma spectrometry, and the 90Sr activities were measured through beta radiation. From the obtained values, the radionuclide transfer factors (TFs) from soil to crop biomass were calculated. The average area activity of 137Cs in the soil around Dukovany and Temelín was 1700 and 2400 Bq m−2, respectively. The average area activity of 90Sr around Dukovany and Temelín was 211 and 184 Bq m−2, respectively. The TF 137Cs ranged from < 6.3 × 10−6 to 7.9 × 10−3, with a mean of 3.5 × 10−4 m2 kg−1, and the TF 90Sr ranged from 2.7 × 10−4 to 6 × 10−2, with a mean of 1.7 × 10−2 m2 kg−1.
