Radioactivity of 137Cs of plant samples taken in former Semipalatinsk Nuclear Test Site (SNTS) was determined. The radioactivity ranged from 0.3 to 81.1 Bq/kg, most of them were under background level but the distribution was localized. Compared to the soil, the plants did not have strong radioactivity, suggesting a potential that plants in this site absorbs radiocesium from soil when the chemical situation of the soil might change, causing fixed Cs turn to be available.
