The object of this research is radionuclide contamination and radiation dose of birds inhabiting the Chornobyl Exclusion Zone. The objective of this research is to assess levels of radioactive contamination of organisms of various species of birds', as well as to assess the amount of radionuclides transfer outside the Zone. In 2004 the International Radioecological Laboratory performed a set of activities aimed at studying 90Sr and 137Cs accumulation peculiarities in organisms of small sparrows within the Chornobyl zone using the method of lifetime measurements of birds general radioactivity. Birds were caught from different areas of the Chornobyl zone. Analysis related to birds' contamination was implemented according to a contamination level of the area where birds were caught (in accordance with data of cartographic materials). Besides, seasonal changes of birds' contamination, species and age differences, period of birds' vital activity, feed peculiarities, degree of mobility of each bird species and position in biotope were assessed. Activities were implemented by the support of Civilian Research and Development Foundation (UB1-2507-KV-03) fund. Data regarding to radionuclides content in 228 birds that are related to 23 species were received during the year. Product Description popup.authors popup.nrat_date 2020-04-02 Close
