Abstract: «Maximum of activity of the Chernobyl-originated 137Cs in edaphic complexes of the River Vytebet uplands is observed at a depth of 8 cm (437,7 becquerel/kg) and 23 cm (312 becquerel/kg). Based on radiocaesium method calculation wash-out rates had reduced from 1,9 cm since the 1986-1994 yrs. period to 0,5 сm during 1995-2010 yrs. period».

Forests and forestry: radiation protection measures with special reference to the Chernobyl accident zone

Title:Forests and forestry: radiation protection measures with special reference to the Chernobyl accident zone

Author: F.A. Tikhomirov, A.I. Shcheglov, V.P. Sidorov

Reference: Science of The Total Environment, Volume 137, Issues 1–3, 2–4 September 1993, Pages 289-305

DOI: http://dx.doi.org/10.1016/0048-9697(93)90395-M

Keywords: Chernobyl; radiation protection; countermeasures; forest management

Abstract: A large proportion of the area contaminated by the Chernobyl accident in the former USSR is forested and has presented unique problems when considering appropriate post-contamination management and clean-up techniques. These problems are related to the forest’s role as both a source and sink for radioactive contamination. Although it has been suggested that resuspension from forested areas may provide a secondary source of contamination to adjacent land, data collected after the Kyshtym and Chernobyl accidents suggest that forest ecosystems may also be effective in limiting the further spread of contamination away from the point of initial deposition and that this effect will increase over time. Such evidence serves to highlight the importance of these ecosystems in influencing the behaviour of radionuclides immediately after their release to the environment. Management practices for forested areas adopted since 1986 are described and a critical appraisal is presented of engineering-based countermeasures implemented over the initial post-accident period. These were intended to remove large quantities of contaminated materials from the forest environment. However, it is suggested that the natural processes of self-decontamination of trees and forest floor litter layers are sufficiently rapid and efficient to necessitate radical alterations to the technologically based approaches adopted in the first 2 years after the Chernobyl accident.

An assessment of cumulative external doses from Chernobyl fallout for a forested area in Russia using the optically stimulated luminescence from quartz inclusions in bricks

Title: An assessment of cumulative external doses from Chernobyl fallout for a forested area in Russia using the optically stimulated luminescence from quartz inclusions in bricks

Author: V. Ramzaev, L. Bøtter-Jensen, K.J. Thomsen, K.G. Andersson, A.S. Murray

Reference: Journal of Environmental Radioactivity, Volume 99, Issue 7, July 2008, Pages 1154-1164

DOI: http://dx.doi.org/10.1016/j.jenvrad.2008.01.014

Keywords: Chernobyl fallout; Forest; Cumulative dose; Fired quartz; Red clay brick; Optically stimulated luminescence

Abstract: Optically stimulated luminescence (OSL) has been used for estimation of the accumulated doses in quartz inclusions obtained from two fired bricks, extracted in July 2004 from a building located in the forested surroundings of the recreational area Novie Bobovichi, the Bryansk Region, Russia. The area was significantly contaminated by Chernobyl fallout with initial 137Cs ground deposition level of ∼1.1 MBq m−2. The accumulated OSL doses in sections of the bricks varied from 141 to 207 mGy, of which between 76 and 146 mGy are attributable to Chernobyl fallout. Using the OSL depth-dose profiles obtained from the exposed bricks and the results from a γ-ray-survey of the area, the Chernobyl-related cumulative γ-ray dose for a point detector located in free air at a height of 1 m above the ground in the study area was estimated to be ca. 240 mGy for the time period starting on 27 April 1986 and ending on 31 July 2004. This result is in good agreement with the result of deterministic modelling of the cumulative γ-ray dose in free air above undisturbed ground from the Chernobyl source in the Bryansk Region. Over the same time period, the external Chernobyl-related dose via forest pathway for the most exposed individuals (e.g., forest workers) is estimated to be ∼39 mSv. Prognosis for the external exposure from 1986 to 2056 is presented and compared with the predictions given by other investigators of the region.

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.
