Abstract: ► Soil samples were collected at about 20 km south of Fukushima Daiichi Nuclear Power Plant. ► The concentrations of 131I, 134, 136, 137Cs and 129mTe were obtained, but 103Ru was not. ► This suggests that noble gasses and volatile radionuclides predominated in the releases. ► Activity ratio of 134Cs/137Cs from the power plant to the south was abound 0.90.

Abstract: ► We evaluate the correlation of SOC with 210Pbex and 137Cs in forest environments. ► SOC shows strong and persistent affinity to 210Pbex than 137Cs. ► In forest soil, SOC and 210Pbex are replenished continuously from natural sources. ► 210Pbex model can help to trace SOC in forests around the world.

Title: The University of Arizona Institutional Repository: Radiocarbon Volume 48 (2006) Number 3 RADIOACTIVE GRAPHITE DISPERSION IN THE ENVIRONMENT IN THE VICINITY OF THE CHERNOBYL NUCLEAR POWER PLANT
Author: Buzinny, Michael
Reference: The University of Arizona, Geosciences, May 2011
Keywords: graphite, soil, forest
Abstract: This paper estimates the radioactive graphite dispersion on the land surface (forest litter and soil) as a result of the Chernobyl Nuclear Power Plant (NPP) release. Graphite mass was calculated using an estimated average concentration of 2.5 × 107 Bq/kg C (carbon). The sample collection method, sample origin and its mass, and sample preparation procedure used for preparation of benzene were taken into account to obtain the optimum sensitivity of the method. Thus, the sensitivity of the corresponding method for graphite detection in forest litter was estimated to be 0.2 mg/m2. All analyses gave a range of deposited graphite from 0.12 to 52.6 mg/m2. The maximum value was observed at a site located 9 km west of the Chernobyl NPP. The results of the study indicate the importance of studying the upper layer of soil (0–5 cm) in addition to the lower layer of forest litter.

Title: Transgenic plants are sensitive bioindicators of nuclear pollution caused by the Chernobyl accident.
Author: Kovalchuk, I / Kovalchuk, O / Arkhipov, A / Hohn, B
Reference: Nature biotechnology, 16 (11), p.1054-1059, Nov 1998

Keywords: Chernobyl; radionuclides; radiolysis; soil; water ecosystems; bioaccumulation; transition ratio; radiomorphosis
Abstract: To evaluate the genetic consequences of radioactive contamination originating from the nuclear reactor accident of Chernobyl on indigenous populations of plants and animals, it is essential to determine the rates of accumulating genetic changes in chronically irradiated populations. An increase in germline mutation rates in humans living close to the Chernobyl Nuclear Power Plant site, and a two- to tenfold increase in germline mutations in barn swallows breeding in Chernobyl have been reported. Little is known, however, about the effects of chronic irradiation on plant genomes. Ionizing radiation causes double-strand breaks in DNA, which are repaired via illegitimate or homologous recombination. We make use of Arabidopsis thaliana plants carrying a beta-glucuronidase marker gene as a recombination substrate to monitor genetic alterations in plant populations, which are caused by nuclear pollution of the environment around Chernobyl. A significant (p<0.05) increase in somatic intrachromosomal recombination frequencies was observed at nuclear pollution levels from 0.1-900 Ci/km2, consistent with an increase in chromosomal aberrations. This bioindicator may serve as a convenient and ethically acceptable alternative to animal systems.

- Title: The mobility of Chernobyl-derived 137Cs in a peatbog system within the catchment of the Pripyat River, Belarus
Author: A Kudelsky, Jim Smith, S Ovsiannikova and J Hilton
Reference: Elsevier, 1996
doi: 10.1016/0048-9697
Keywords: Pripyat,River,Soil, Belarus,137Cs
Abstract: The behaviour of Chernobyl-derived 137Cs in a hydrologically isolated bog system in the catchment of the Pripyat river in Belarus was investigated. Measurements were made of 137Cs activities in the solids and pore waters of the bog soils, as well as the variability in activity in water draining from the bog. It was found that the radiocaesium activity of the pore water, and hence the measured distribution coefficient, Kd, was dependent upon the pressure at which the water was removed from the soil.

Abstract: Six years after the accident at the Chernobyl Nuclear Power Plant, the behaviour of radionuclides in soils in rural areas of Ukraine, Belarus and Russia has been studied. Measurements were made to determine the total radioactive contamination, the fuel particle contribution, and the distribution and extractability of the radionuclides 137Cs and 90Sr. Inside the 30 km restriction zone around the plant, particles of highly irradiated fuel accounted for most of the radioactive contamination.
