    Abstract:
    We studied the concentration and distribution of (137)Cs and (90)Sr in the bodies of 188 wild boar (Sus scrofa Linnaeus, 1758) taken near the Chernobyl site. Of these, 111 animals were taken in the Alienation Zone, 41 animals were taken in the Permanent Control Zone and 36 animals were taken in the Periodic Control Zone. The samples included muscle and bone (rib) tissues and samples of heart, liver, lungs, kidneys, spleen, genitals and skin. The weight of the samples was 0.5 kg fresh weigh. The average concentration of (137)Cs in the muscles of the wild boar found in the Alienation Zone was 46 ± 10 kBq/kg, in the Permanent Control Zone - 13 ± 3.0 kBq/kg and in the Periodic Control Zone - 0.6 ± 0.1 kBq/kg. The largest concentration of (137)Cs was detected in the muscle tissue and kidneys taken animals. In some samples of muscle tissue it reached more than 660 kBq/kg. The (137)Cs concentrations were also high in heart and spleen up 64.3 kBq/kg and 67.5 kBq/kg - animals from the Alienation Zone and 10.3-10.6 kBq/kg - animals from the Permanent Control zone. The lowest concentration of (137)Cs was found in the lungs and skin of animals. The analyses of (90)Sr concentration in the organs and tissues of the wild boar showed that (90)Sr was concentrated mainly in the bone tissue. The average level of (90)Sr concentration in bone was 17.6 kBq/kg fresh weight animals from the Alienation Zone and 13.47 kBg/kg - animals from the Permanent Control zone. In muscle tissues and organs contained (90)Sr - 30.0-110.0 Bq/kg in the Alienation Zone and 11.0-30.0 Bq/kg in the Permanent Control zone.
