Plants as indicators of tritium concentration in ground water at the Semipalatinsk test site

- The groundwater areas contaminated with 3H are one of Semipalatinsk test site issues.
- In this paper, contaminated plants are considered as indicators of possible 3Н contamination of ground water.
- It was found high level of 3Н activity concentrations in plants (up to 85 kBq/kg) in areas of ground water contaminated.
- Dependence of 3Н activity concentration in plants on 3Н activity concentration in ground water has been revealed.
