Abstract: We tried the decontamination of surface soils for three types of agricultural land at Nagadoro district of Iitate-mura (village) in Fukushima Prefecture, which is highly contaminated by deposits of radionuclides from the plume released from the Fukushima Daiichi nuclear power plant. The decontamination method consisted of the peeling of surface soils solidified using a polyion complex, which was formed from a salt solution of polycations and polyanions. Two types of polyion complex solution were applied to an upland field in a plastic greenhouse, a pasture, and a paddy field. The decontamination efficiency of the surface soils reached 90%, and dust release was effectively suppressed during the removal of surface soils.

DOI: http://dx.doi.org/10.11440/rssj1981.6.165
Keywords: satellite, Landsat, radioactive fallout
Abstract: Regarding the Chernobyl Nuclear disaster; NOAA/AVHRR and Salyut/KATK-140 imageries show the land cover condition of the wide area around the nuclear complex. Landsat TM image acquired on 29 April 1986 informs us the thermal condition of the exploded reactor and suggests the heavy deposition area. Landsat TM image on 26 April 1985, before the accident, shows the normally operated condition in the reservoir. Also Spot HRV 10 meter resolution image exhibits the planimetric configuration of the complex.

Title: Concentration of Radioactive Cesium in Imported Foods and Contribution by Chernobyl Reactor Accident
Author: Kazuyoshi FUKUDA
Reference: RADIOISOTOPES, Vol. 49 (2000) No. 9 P 433-438
DOI: http://dx.doi.org/10.3769/radioisotopes.49.433
Keywords: radioactive cesium, potassium-40, imported food, Chernobyl reactor accident
Abstract: Radionuclides in imported foods consumed in Hokkaido were examined by germanium (Ge) gamma-ray spectrometer system.
The values of radioactive cesium (137Cs+134Cs) concentration of 480 samples collected during 1989-1999 were lower than the temporary limit (370Bq/kg) . These values of 441 samples (92%) were lower than 1 Bq/kg. The maximum values of 137Cs and 134Cs were 62.4Bq/kg, 3.8Bq/kg in black tea imported from China.
From the relation between concentration of 137Cs and cesium unit, the contribution from Chernobyl reactor accident was estimated qualitatively on 24 samples with higher values than 0.40Bq/g-K. Based on the concentration of 134Cs and 137Cs detected in 16 samples, the contribution of 137Cs from this accident were calculated.

Keywords:reconstruction, inhalation and oral intake of 131І, radioisotopes of cesium (137Cs; 134Cs), noble radioactive gases (85mKr; 133mXe), Effective dose, 06Ru, 103Ru, 141Ce, 144Ce, 95mNb, 132Te, 140Ln
Abstract: Results of retrospective reconstruction of average individual radiation doses got by residents of the South Ukraine due to exposure to radioactive fallouts from the Chernobyl NPP are given in the article. In the work radiometry, spectrometry and dosimetry data collected in the territory of Nikolev, Odessa, Kirovograd oblasts and Autonomous Republic of Crimea were used. The study was carried out by the Nikolaev Research Laboratory Larani in 1986 and later.

Title: Distribution of individual and collective exposure doses for the population of Belorus in the first year after the Chernobyl accident
Author: Savkin M.N., Titov A.V., Lebedev A.N.
Reference: Journal: Radiation and Risk (Bulletin of the National Radiation and Epidemiological Registry), Year: 1996 Release Number: 7
Keywords: individual doses, collective dose, Belarus
Abstract: The paper presents results of reconstruction of absorbed internal and external exposure doses for the population on the contaminated areas of Belorus in 1986 on the basis of statistical analysis of the database on radiation monitoring of environmental media, foodstuffs and individual exposure. Consideration is given to the areas with 137Cs soil contamination density of above 0.185 MBq/m2 (5 Ci/km2). A model of basic distributions is proposed which can be used to estimate distribution of absorbed doses for evacuated population and those living permanently on these areas during 1986 with allowance for taken protection measures. The obtained results are compared to the prompt assessments made earlier which were used for decision making and with the features of formation of the radiation situation of the territories adjacent to Russia.

Title: Doses and risks from the water use received by the population of southwest areas of Bryansk region
Author: Katkova M.N.
Reference: Journal: Radiation and Risk (Bulletin of the National Radiation and Epidemiological Registry), Year: 2008, Volume: 17, Issue: 1
Keywords: exposure dose, water use, risk, radionuclides of 90 Sr and 137Cs, Chernobyl accident
Abstract: In the present work the estimation of risk for the population of southwest areas of Bryansk region exposed to radiation fallout after Chernobyl accident is carried out. The life risk of disease for the population of the specified areas is estimated by a cancer through a dose received from water use. The basic ways of radionuclide receipt in an organism of inhabitants of southwest areas of Bryansk region on a water chain are: an external exposure from polluted flood-land of water body, consumption of water from the sources of the drinking water supply located in the polluted zone, and consumption of fish caught from a local water body. As object of research the population living in area of Lake Kozhanovskoe is accepted. The contribution of radionuclides o f9 Sr and 137Cs in a total dose from water use is estimated. Priority sources of risk for the population from water use to which it is necessary to pay special attention at carrying out of protective actions in the specified territories are revealed.
