Reference: Journal of Radioanalytical and Nuclear Chemistry 1 November 1988, Volume 128, Issue 4, pp 273-281
DOI: 10.1007/BF02166951
Keywords: Radioactive pollution, Turkey, biota
Abstract: Long-lived fission radionuclides spread out after the Chernobyl accident have been measured in samples collected from the Black Sea and at the Aegean coasts of Turkey between June 15 and September 15, 1987. Nondestructive analysis was performed using high resolution γ-spectroscopy. The activity remaining 16 months after the event was found to be enhanced in coniferous needles as well as in lichens, while foodstuff did not show any appreciable contamination. The relatively high106Ru/134Cs and144Ce/134Cs ratios compared to those found in analogous samples from Southern Europe, might result from a fractionation between refractory and volatile elements.

Title: Dynamic modeling of the radionuclides transfer within hydrobiocenosis and assessing the consequences of radioactive contamination for biota and human
Author: Kryshev, Alexander Ivanovich
Reference: Obninsk, 2008
Keywords: biota, humans, radionuclides, environment, radiation monitoring, hydrobiocenosis, water reservoirs
Abstract: The purpose of this study was to develop an integrated assessment model of the effects of radioactive contamination of hydrobiocenosis on biota and humans, based on the information about the entry of radionuclides into the environment and the radiation monitoring data.

Title: Interference of soil and radioactivity in Polesia ecosystems and in Opolye (natural area) of south east Russia
Author: Prosyannikov Evgeny
Reference: Moscow,1995
Keywords: ecosystem, Polesia, soil, biota, Opolye
Abstract: The purpose of the study; to research the effect of natural soil and various agroecosystems of Polesia and Opolye (natural land) on the behavior of radionuclides, and the impact of anthropogenic factors on the living stage of soil for the characterization of the conditions of human life.

Title:Plutonium, 137Cs and 90Sr in selected invertebrates from some areas around Chernobyl nuclear power plant
Author: Jerzy W. Mietelski, Svetlana Maksimova, Przemysław Szwałko, Katarzyna Wnuk, Paweł Zagrodzki, Sylwia Błażej, Paweł Gaca, Ewa Tomankiewicz, Olexandr Orlov
Reference: Journal of Environmental Radioactivity, Volume 101, Issue 6, June 2010, Pages 488-493
DOI:http://dx.doi.org/10.1016/j.jenvrad.2008.04.009
Keywords: Plutonium; 90Sr; 137Cs; Chernobyl; Invertebrates; Radioactive contamination of biota
Abstract: Results are presented for 137Cs, 90Sr and plutonium activity concentrations in more than 20 samples of terrestrial invertebrates, including species of beetles, ants, spiders and millipedes, collected in the highly contaminated area of the Chernobyl exclusion zone. The majority of samples were collected in Belarus, with some also collected in the Ukraine. Three other samples were collected in an area of lower contamination. Results show that seven samples exceed an activity concentration of 100 kBq/kg (ash weight – a.w.) for 137Cs. The maximum activity concentration for this isotope was 1.52 ± 0.08 MBq/kg (a.w.) determined in ants (Formica cynerea). Seven results for 90Sr exceeded 100 kBq/kg (a.w.), mostly for millipedes. Relatively high plutonium activity concentrations were found in some ants and earth-boring dung beetles. Analyses of activity ratios showed differences in transfer of radionuclides between species. To reveal the correlation structure of the multivariate data set, the Partial Least-Squares method (PLS) was used. Results of the PLS model suggest that high radiocesium activity concentrations in animal bodies can be expected mainly for relatively small creatures living on the litter surface. In contrast, high strontium activity concentrations can be expected for creatures which conduct their lives within litter, having mixed trophic habits and a moderate lifespan. No clear conclusions could be made for plutonium.

- Title: Doses to members of the general public and observed effects on biota: Chernobyl Forum update.
Author: Anspaugh, Lynn R
Reference: Journal of Environmental Radioactivity, 96 (1-3), p.13-19, Jul 2007
doi:10.1016/j.jenvrad.2006.12.001
Keywords: Chernobyl; Radiation; Collective effective dose; Thyroid dose; Effects; Biota; Humans; Accident
Abstract: The Chernobyl Forum was organized by the United Nations to examine the health and environmental effects of the accident at the Chernobyl Nuclear Power Station. This paper is concerned with the environmental effects, as determined by Expert Group Environment. The accident resulted in release of a large amount of radioactive materials over a period of 10 days. These materials were deposited throughout Europe with the three more affected countries being Belarus, Russia, and Ukraine.
