Abstract. The dataset “Spatial datasets of radionuclide contamination in the Ukrainian Chernobyl Exclusion Zone” was developed to enable data collected between May 1986 (immediately after Chernobyl) and 2014 by Institute Agricultural Radiology (UIAR) accident be made publicly available. includes results from comprehensive soil sampling across Zone (CEZ). Analyses include radiocaesium (134Cs 134Cs) 90Sr, 154Eu property data; plutonium isotope activity concentrations (including distribution...
Weathering of fuel particles and the subsequent leaching radionuclides causes 90Sr mobility in Chernobyl soils to increase with time after deposition. Studies speciation collected 1995 1996 from 30-km exclusion zone have been used calculate rates dissolution under natural environmental conditions. Results show that velocity particle is primarily dependent on physico-chemical characteristics partially soil acidity. Compared other areas, rate significantly lower contaminated areas west reactor...
Fuel particles released during the accident at Chernobyl reactor (1986) and operation Windscale (UK) pile (1952–57) were investigated with respect to structure using scanning electron microscopy composition X-ray microanalysis γ-, β- α-spectrometry. Particles from a relatively high temperature have in general compact crystalline-like uniform surface layer of uranium. Aggregates consisting small-sized (1–2 µm) spherical uranium granulates also identified. These similar identified Norway....
This paper compares the scale and consequences of radioactive contamination forest ecosystems following Chernobyl Fukushima accidents. The deposition in zone closest to reactor site (the "near zone") presently consists 137Cs, 90Sr isotopes transuranium elements, while only long-lived radionuclide release was 137Cs. Radiocesium levels near zones two accidents are similar. We compare effects radiation on forestry Acute after accident caused death Scots pine (Pinus sylvestris L.) forests close...
Transfer factors are key inputs for modelling the transport of radionuclides in environment and assessment risk to humans wildlife. However, many combinations soil conditions, plant species (products), radionuclides, such information is limited. The use transfer stable elements absence on their radioactive isotopes quite common. question legality an approach arises. For this purpose, work was carried out establish relationship between accumulation coefficients (137Cs 90Sr) isotopes. research...
To identify effects of chronic internal and external radiation exposure for components terrestrial ecosystems, a comprehensive study Scots pine trees in the Chernobyl Exclusion Zone was performed. The experimental plan included over 1,100 young (up to 20 y old) selected from areas with varying levels radioactive contamination. These were planted after 1986 Nuclear Power Plant accident mainly prevent radionuclide resuspension soil erosion. For each tree, major morphological parameters...
Following the 1986 Chornobyl accident, an area approaching 5000 km2 surrounding nuclear plant was abandoned, creating exclusion zone (CEZ). Although this likely contains most radioactive terrestrial ecosystem on earth, absence of humans and associated activities for nearly 35 years since accident has resulted in increases wildlife numbers. Both Belarussian Ukrainian components CEZ are now designated as nature reserves; together they form one Europe's largest protected areas have been...
