The transfer of 238U and 226Ra to Chinese cabbage (Brassica rapa L. subsp. pekinensis (Lour.) Hanelt) was investigated from soils contaminated with uranium-mill tailings (UMT) by means of a pot experiment in laboratory-based conditions applying different levels of soil contamination under various growing conditions. Activity concentrations for 226Ra in Chinese cabbage varied from 56–276, 156–502 and 277–877 Bq kg−1 dry mass for 20, 40 and 60 % of UMT content in the soil, respectively, and for 238U from 1.0–2.3 and 2.3–4.7 Bq kg−1 dry mass for 40 and 60 % of UMT content in the soil, respectively. The results showed increased accumulation of 226Ra and low accumulation of 238U in cabbage leaves in more contaminated soil.
