Author: Porovsky Ya.V., Domnikova R.S., Tetenev F.F.
Reference: Siberian State Medical University
Keywords: Chernobyl event liquidators, peripheral blood, bone marrow.
Abstract: Results of peripheral blood analysis, performed annually during 12—14 years in 83 Chernobyl event liquidators and of the marrow which was analyzed once, at the end of abovementioned period in 23 participants are given. Changes in peripheral blood showed increased number of reticulocytes, lymphocytes, monocytes and decreased number of thrombocytes. Cellular structure of the marrow revealed decreased mean number of myelocytes, basophil and polychromatophil normoblasts and increased number of lymphoid and monocyte population cells. The deflections revealed in the hemopoiesis system may serve as reflection of continuing regeneration processes in the bone marrow and increased amount of somatic pathologies.

Abstract: In the spring of 1986, the aftermath of the Chernobyl nuclear explosion left a substantial portion of the forested area of the Ukrainian Polissya region contaminated with radioactive fallout.  Although less than 14.5% of Ukraine is forested, nearly one-quarter (24.2%) of its woodlands (appox.2,371,600 ha) are located in the Polissya region.

Annotation:This work is devoted to a problem of influence of low doses radiations on peripheral blood in children and adolescents, who are living in northern areas of Zhitomir region.The conditions of children’s health, who are living in radiated polluted area was studied. Children’s deaseses at postaccident period was investigated. Total and characteric changes of health conditions due to low doses radiations was determined. The epidemiology of inner radiation toward incorporation radiocezium level was studied. Different inner radiation doses influence on blood system was investigated.Peripheral blood conditions data in children and adolescents due to radiated polluted environment and tot al inner radiotions activity was determined. The correlative analisis of different peripheral blood data in children and adolescents due to the level of` inner radiotions density activity was performed.

Radioactivity in mushrooms, mosses and soil samples of defined biotops in SW Bavaria-two years after “Chernobyl”

Keywords : Cesium isotopes, Chernobyl, 40K, Mushrooms

Abstract:Mushrooms, the moos/grass layer and soil samples have been collected in autumn 1987 from two sites in SW-Bavaria in continuation of a former investigation (Elstner et al. 1987). There were still relatively high amounts of 137Cs and 134Cs in all samples. The ratio 137Cs/134Cs changed according to the different half-life times of the two radioisotopes, indicating in nearly all cases the Chernobyl accident as source. The distribution of the radioisotopes within the mushroom populations shows considerable variation, even within the same species and location. Besides 137Cs, 134Cs and 40K no other radioisotopes were detected.

Effect of chronic irradiation on plant resistance to biotic stress in 30-km Chernobyl nuclear power plant exclusion zone

Keywords : Triticum aestivum, Secale cereale, Zea mays, Erysiphe graminis, Puccinia triticana, P. graminis, phytoimmunity, exclusion zone of Chernobyl Nuclear Power plant, low doses of chronic irradiation, plant inhibitors of proteinases

Abstract:It was established in greenhouse experiments that infection with powdery moldew (Erysiphe graminis DC. f. sp. tritici Em. Marchal) and brown rust (Puccinia triticana Erikss. & Henn.) of three wheat (Triticum aestivum L.) cultivars (Mironovskaya 808, Polesskay 70, and Kiyanka) grown from seeds, collected in the Chernobyl exclusion zone, was 1.5–2.0 times higher than of plants grown from control seeds. On field trials in the Chernobyl zone, wheat plant resistance to biotic stress was reduced. At artificial infection with brown rust, the disease development was enhanced on plots with increased radiation background. One of the mechanisms of the declined phytoimmunity potential under the action of low doses of chronic irradiation is evidently a reduced activity of plant proteinase inhibitors. Thus, in wheat and rye (Secale cereale L., cv. Saratovskaya) grains, their activity reduced by 35–60% as compared to control. Active form and race formation in the population of the cereal stem rust causal agent (Puccinia graminis Pers.) was observed in the Chernobyl zone. A “new” population of this fungus with high frequency of more virulent clones than in other Ukraine regions was distinguished. The results obtained independently in greenhouse and field trials performed in the Chernobyl zone demonstrated radiation stress influence on the pathogen-plant interactions. They indicate a necessity of monitoring the microevolutionary processes occurring in both plants and their pathogens under conditions of technogenic stresses.

Radioactivity in rainwater following the Chernobyl accident

Title: Radioactivity in rainwater following the Chernobyl accident

Author: Dennis A. Wheeler

Reference:Environmentalist , Spring 1987, Volume 7, Issue 1, pp 31-34

Keywords :

Abstract:Rainfall is a widely-acknowledged vehicle for the removal and deposition at ground level of atmospheric-borne materials. The events following the Chernobyl accident demonstrated once again the importance of atmospheric conditions in dispersing, transporting and depositing pollutants. Much attention has been paid to the contamination of vegetation and food products, yet the quality of the contaminated rainwater has been overlooked. This paper reports and summarises the findings from Great Britain and Scandinavia and shows that the issue is far from simple or easily understood.

Abstract: The present study addresses the monitoring of children from the Belorussian and Ukrainian Republics exposed to the fall-out of the Chernobyl accident. Micronucleus analysis has been performed on 56 children from different areas. The micronucleus frequencies in individuals as well as in regional groups were comparable with controls, except for three donors. Such results had to be expected, taking into account that at least 7 years have passed since the accident. Most of the children whose micronucleus frequencies were determined are suffering from thyroid cancer and were treated by radioiodine (131I) therapy. We studied the effect of in vitro exposure with 131I on micronucleus induction and that proliferative ability of lymphocytes. The present investigation indicates that micronuclei can be usefully employed to detect individual exposures to the incorporated radionuclide within several days after the intake of the radionuclide in a dose range of around 65-390 mGy (effective dose).

Keywords : Placenta; Trophoblast; Ionizing radiation; Microarray; JP4-039

Abstract: Exposure to low-dose radiation is widespread and attributable to natural sources. However, occupational, medical, accidental, and terrorist-related exposures remain a significant threat. Information on radiation injury to the feto-placental unit is scant and largely observational. We hypothesized that radiation causes trophoblast injury, and alters the expression of injury-related transcripts in vitro or in vivo, thus affecting fetal growth.
