The content of 137Cs and 90Sr radionuclides in lizards of Lacertidae family. Activity concentration of 90Sr radionuclide in lizards' bodies achieved values of 7.8 × 105 Bq kg−1. Mean CR values were as follows: 137Cs–6.2 × 10−3, 90Sr–1.1 × 10−2. CR values can depend on character of ground contamination.
