Radioactivity of 137Cs in Plant Samples at Former USSR Nuclear Test Site

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 radioactiv...

Zusammenfassung: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.
