Review of Russian language studies on radionuclide behaviour in agricultural animals: Transfer to animal tissues.

Data on radionuclide transfer to animals from research performed in the former Soviet Union were reviewed to collate transfer coefficient values (F) to animal tissues such as liver, kidney and bone, but not muscle which has previously been reported. The derived values were compared with selected data published in the English language literature. The new data are mainly for Sr and Cs, although some data were also provided for H, Mn, Fe, Co, Na Zn, I and U.

[Radiological Aspects of Transition of Russian Areas Affected by the Chernobyl Accident to Normal Activities].

Dynamics of radiation situation in settlements, agriculture and forestry on the Russian Federation areas af- fected by the Chernobyl accident is presented. A set of challenging problems on public radiation protection and rehabilitation of territories was determined. The main objective at a long-term period after the accident is a stage-wise return of the affected areas to normal activity without any radiological criteria restrictions.

Review of Russian language studies on radionuclide behaviour in agricultural animals: biological half-lives.

Extensive studies on transfer of radionuclides to animals were carried out in the USSR from the 1950s. Few of these studies were published in the international refereed literature or taken into account in international reviews. This paper continues a series of reviews of Russian language literature on radionuclide transfer to animals, providing information on biological half-lives of radionuclides in various animal tissues.

[Quantitative dependence of sheep death on dose and dose rate of external gamma-radiation].

The results of experimental studies of sheep death at different dose rates of gamma-radiation have been analyzed. Parameters of a mathematical dependence of animal death on the exposure dose and dose rate have been identified. The evaluation of adequacy of the derived equation has demonstrated that the established relationship correctly describes the experimental data in studied dose rate range.

Rural areas affected by the Chernobyl accident: radiation exposure and remediation strategies.

Main objectives of the present work were to develop an internationally agreed methodology for deriving optimized remediation strategies in rural areas that are still affected by the Chernobyl accident, and to give an overview of the radiological situation in the three affected countries, Belarus, Russia and Ukraine. Study settlements were defined by having in 2004 less than 10,000 inhabitants and official dose estimates exceeding 1 mSv. Data on population, current farming practices, contamination of soils and foodstuffs, and remedial actions previously applied were collected for each of such 541 study settlements.
