The concentrations of 90Sr in mammal teeth taken in north-west part of Semipalatinsk Test Site were measured by using imaging plates. The highest concentration detected in the present study was 13Bq/g, being comparable with the values previously detected in cow teeth from South Ural region. It suggests that, at least locally, the soil in north-west part of the Test Site is possibly highly contaminated. It would be necessary to investigate the source of this high level of contamination, such as radiological weapon tests, before providing the land for agricultural use.
