Abstract: After Chernobyl in April 1986, radioactive cesium has been measured in Øvre Heidalsvatn, a Norwegian subalpine lake, situated in an area of high fallout. The lake is an important reference site and has been the subject of extensive ecosystem studies since the 1950s. Emphasis has been given to measuring long-term trends in the activity content of radioactive cesium in the Brown trout (Salmo trutta) population.

Keywords: Radiocesium; mercury; lead; crucian carp; Chernobyl
Abstract: Samples of crucian carp (Carassius carassius) and sediments collected from 14 ponds within and outside the 30 km exclusion zone southeast of Chernobyl were analyzed for radiocesium; major anions and cations in water were determined for each pond, and other atmospherically- transported pollutants (Pb and Hg) were measured in fish muscle.

Keywords: Chernobyl; Forest; Radiocaesium
Abstract: An assessment of the distribution of Chernobyl fallout in a Swedish forest was carried out and showed more than 95% of the in the system to be of Chernobyl origin. The data show that approximately 87% of total fallout is found in soils, 6% in the bryophyte layer and 7% in standing biomass of trees. The mean deposition of in the system (including soils, bryophytes, understorey vegetation, fungi, trees, moose and roe deer) was 54 kBq m−2. Fungi, understorey vegetation and ruminant populations collectively contained approximately 1% of total radiocaesium in the system.

- Title: A long-term field study on the effect of acid irrigation and compensatory liming on the transport of Chernobyl-derived radiocesium in a forest soil
Author: Schimmack, W. / Bunzl, K. / Kreutzer, K.
Reference: Science of The Total Environment, 198 (3), p.271-285, May 1997
doi: 10.1016/S0048-9697(97)05454-5
Keywords: Radiocesium; Chernobyl; Forest soil; Migration; Acid rain; Liming
Abstract: The effect of acid irrigation with and without liming on the vertical transport of Chernobyl-derived 134Cs in the soil was investigated in a Norway spruce stand by field experiments. For this purpose seven plots with different treatments were established. After 5 years of observation to detect differences in the residence half-time’s of 134Cs in the various soil horizons with respect to the control sites, the plots were sampled at 18 individual pits. No effect on the residence half-time of 134Cs was observed for ‘normal’ irrigation (pH 5.3) as compared to the control in all organic horizons.

- Title: Variation in transfer factor of radiocaesium in bank voles (Clethrionomys glareolus) in clear cut and mature forest sites after the Chernobyl accident
Author: Palo, Thomas R.
Reference: Journal of Environmental Radioactivity, 92 (2), p.112-121, Jan 2007
doi: 10.1016/j.jenvrad.2006.10.002
Keywords: Bank vole; Chernobyl fallout; Sweden; Forest habitat
Abstract: Bank voles that were collected between 1986 and 2004 at sites in Chernobyl fallout areas of northern Sweden showed higher 137Cs activity concentrations at the mature forest sites compared to clear cuts. This difference was not attributed to differences in ground deposition between sites but to differences in aggregated transfer rates to voles. Differences in transfer between forest types were evident for all years 1986–2004 but the change occurred at different rates in the two habitats.

Keywords: Catfish, Chernobyl DNA damage, Micronuclei Radiocesium
Abstract: The explosion of the Chernobyl Nuclear Power Plant resulted in some of the most radioactively contaminated habitats on earth. Despite evacuation of all human inhabitants from the most contaminated areas, animals and plants continue to thrive in these areas. This study examines the levels of contamination and genetic damage associated with radiocesium in catfish (Ictalurus punctatus) from the cooling pond and a control site. In general, catfish from the cooling pond exhibit greater genetic damage, and the amount of damage is related to the concentration of radiocesium in individual fish. Genetic damage is primarily in the form of DNA strand breaks, with few micronuclei being observed in contaminated fish. The possible roles that acclimation and adaption play in the response to high levels of radiation exposure are discussed.

Keywords: Modelling; Radiocaesium; Fish; Chernobyl
Abstract: After the sudden fallout from the Chernobyl nuclear accident in 1986, activities and bioaccumulation factors of radiocaesium (137Cs, 134Cs) fluctuated strongly over several years before reaching quasi-equilibrium, with patterns significantly differing among organisms.

Keywords: Milk; Cattle; Radiocaesium; Radiostrontium; Bioavailability; Chernobyl exclusion zone
Abstract: A study conducted during summer 1993 to determine the bioavailability and transfer of 137Cs and 90Sr to dairy cattle from herbage collected from a pasture contaminated by particulate fallout is described. The study pasture was located 3.5 km from the Chernobyl nuclear power plant. The true absorption coefficient (At) determined for 137Cs (0.23) was considerably lower than previous estimates for radiocaesium incorporated into vegetation by root uptake.

Three biomass systems were envisaged: forestry, short rotation coppice (SRC) and perennial grasses.

Abstract: The field of radioecology deals with the fate and effects of radioactive contaminants in the environment. It relies upon and contributes to the principles of both radiation biology and basic ecology and is a special case of the more general field of environmental toxicology. Effects studies deal with populations, communities, and ecosystems and have involved the establishment of radiation sources within a variety of natural vegetation communities.
