“…This concerned reed (Phragmites australis L.), lymnaea (Lymnaea stagnalis L.) [6], pine (Pinus sylvestris L.) [13,21], thin bluegrass (Koeleria gracilis L.) [22], biennial goat's-rue (Oenothe rabiennis L.), and they all were affected by chronic high-dose external and internal ionizing radiation. Accordingly, the real dose load on meristem cells can exceed by an order the doses calculated for steady irradiation of plant cells [6,19].…”

“…The calculations, based on the studies of radiation after-effects, showed that the probability to identify chromosome aberrations is 10 3 -10 4 times higher than that of the identification of individual locus mutation [11], and the evaluation of a mutative process with the help of cytogenetic analysis gives the results which match those, received by the method of electrophoretic analysis of isoenzymes [12,13].…”

Aim.To study frequency and spectrum of chromosome aberrations in the cells of Triticum aestivum L. root meristem under a prolonged effect of radionuclides from water reservoirs in the proximal alienation zone of the Chernobyl nuclear power plant NPP. Methods. The seeds of two soft winter wheat varieties were treated with samples from water reservoirs in the alienation zone of the Chernobyl NPP. Ana-telophase analysis of chromosome aberrations in crushed cytological preparations of apical meristem of primary rootlets was carried out. Results. Radionuclides from water reservoirs in the proximal alienation zone of the Chornobyl NPP cause an increase in the occurrence of aberrant cells and mitoses by 1.6-4.2 times. The highest level of cytogenetic activity is typical for the radionuclides from the reservoir-cooler of the Chernobyl NPP, Semyhodskyi backwater, drainage N 3 of the NPP and Lake Hlyboke. The obseved aberrations are mostly represented by single and paired acentric fragments, bridges and lagging chromosomes. Conclusion. A prolonged exposure to ionizing radiation by radionuclides from the water reservoirs of the proximal alienation zone of the Chernobyl NPP produces leads to high cytogenetic activity. No correlation between the chromosome aberration level and the scope of specific radionuclides from water reservoirs was found; this may prove the induction of cytogenetic disorders under the radiation effect in the low-rate range. The increased level of aneuploid cells and those with multiple chromosome aberrations confirms genetic сonsequences for the organisms in water reservoirs even with a low specific activity of radionuclides. K e y w o r d s:Aberrations, cytogenetic disorders, radionuclide, low-rate radiation.

“…This research developed from a series of broad-ranging programs supported by the Commission of the European Communities (CEC) to investigate the radiological consequences of the Chernobyl accident (e.g., Karaoglou et al, 1996). Also, in a later study in Russia, a building in a very highly contaminated forested recreational area was examined by Ramzaev et al (2008).…”

“…Forested environment study Ramzaev et al (2008) present the results of a study undertaken in a forested environment, based on an examination of two brick-built structures within the recreational area of Novie Bobovichi, located 20 km NW of Novozybkov in Bryansk Oblast, and ∼180 km NE of the Chernobyl NPP. The fallout deposition in the pineforested recreational area was both heterogeneous and heavy, with an official 137Cs contamination level of 1.1 MBq m −2 in 1986, and the penetration of 137 Cs in soil was relatively shallow (reported to be within 4 cm).…”

“…This study is interesting because the presence of a tree canopy gives rise to a more complex distribution of contamination compared with that obtained in the more open landscapes of Zaborie and Stary Vishkov. Also, Ramzaev et al (2008) based their dose conversion factor on relative gamma dose rate measurements rather than computational modelling. In their radiation transport model for urban environments Meckbach and Jacob (1988) examined the effect of fallout retention within tree canopies and found a potential increase in dose rate within buildings.…”

HIGHLIGHTSReview of the use of luminescence and electron paramagnetic resonance in retrospective and emergency dosimetry.Optically stimulated luminescence (OSL), thermoluminescence (TL) and Electron Paramagnetic Resonance (EPR) results on biological and physical materials.Descriptions of use in emergency and retrospective dosimetry, following large-scale radiological events.http://www.sciencedirect.com/science/article/pii/S1350448716302359 ABSTRACTThis paper reviews recent research on the application of the physical dosimetry techniques of electron paramagnetic resonance (EPR) and luminescence (optically stimulated luminescence, OSL, and thermoluminescence, TL) to determine radiation dose following catastrophic, large-scale radiological events. Such data are used in dose reconstruction to obtain estimates of dose due to the exposure to external sources of radiation, primarily gamma radiation, by individual members of the public and by populations. The EPR and luminescence techniques have been applied to a wide range of radiological studies, including nuclear bomb detonation (e.g., Hiroshima and Nagasaki) nuclear power plant accidents (e.g., Chernobyl), radioactive pollution (e.g., Mayak plutonium facility), and in the future could include terrorist events involving the dispersal of radioactive materials. In this review we examine the application of these techniques in 'emergency' and 'retrospective' modes of operation that are conducted on two distinct timescales. For emergency dosimetry immediate action to evaluate dose to individuals following radiation exposure is required to assess deterministic biological effects and to enable rapid medical triage. Retrospective dosimetry, on the other hand, contributes to the reconstruction of doses to populations and individuals following external exposure, and contributes to the long-term study of stochastic processes and the consequential epidemiological effects. Although internal exposure, via ingestion of radionuclides for example, can be a potentially significant contributor to dose, this review is confined to those dose components arising from exposure to external radiation, which in most studies is gamma radiation.The nascent emergency dosimetry measurement techniques aim to perform direct dose evaluations for individuals who, as members of the public, are most unlikely to be carrying a dosimeter issued for radiation monitoring purposes in the event of a radiation incident. Hence attention has focused on b...
