Caesium-137 of a global origin is found in some regions of Kazan, near the Volga and near the Kama. The greatest density of distribution does not exceed the level of 18,5 kBq/m2. The collective dose of irradiation from global precipitation equals 48 persons/Sv. The content of caesium-137, strontium-90 in milk, meat, potatoes and bread is about 1000 times smaller than the prescribed allowable levels for the present. Technogenic contamination by radium-226 is found in some areas of industrial territories in Kazan, Mendeleevsk, Chistopol, Almetyevsk and Naberezhnye Chelny. Medical radiologic investigations have a pronounced effect on the collective dose of irradiation.
