[Ab] Resumo:The purpose of this study was to give the description of harmful effects of the impact of electromagnetic radiations from base stations of cellular communication as the most common sources of radio frequencies of electromagnetic fields in the environment. The highest values of the energy flux density were measured on the roofs of houses where antennas are installed - more than 10 pW/cm. The lowest values were recorded in inside premises with expositions of 0.1-1 pW/cm. In the close location of the railway station to the base stations of the cellular communication there was seen a cumulative effect. There are proposed both new safe hygienic approaches to the control for the safety of the work of base station and protective measures.

[Ab] Resumo:Traditional medicinal plants are widely used for the treatment of various diseases in Saudi Arabia. Knowledge of chemical composition of these materials is important as it pertains to health. The activity concentrations of 232Th, 226Ra and 40K were measured in twenty-six medicinal plant samples purchased from different local Saudi markets using γ- spectrometry with a NaI[Tl] detector. They ranged between 0.50?0.04 to 13.72?1.15 Bq kg₋1, 0.45?0.04 to 12.73?1.02 Bq kg-1and 7.00?0.50 to 327.06?11.0 Bq kg₋1, respectively. The radium equivalent activity and absorbed dose rate in the studied samples varied from 1.21 to 54.45 Bq kg₋1 and from 0.55 to 28.24 nGyh-1, respectively. Intake of radionuclides in samples was insignificant. Consequently, these samples were considered safe in terms of radiological health hazards. The concentration of six heavy metals: Cd, Pb, As, Cu, Mn and Zn were monitored by inductively coupled plasma optical emission and some of them were found above permissible limit.

[Ti] Título:An aerosol particle containing enriched uranium encountered in the remote upper troposphere.

[Ab] Resumo:We describe a submicron aerosol particle sampled at an altitude of 7 km near the Aleutian Islands that contained a small percentage of enriched uranium oxide. U was 3.1 ±â€¯0.5% of U. During twenty years of aircraft sampling of millions of particles in the global atmosphere, we have rarely encountered a particle with a similarly high content of U and never a particle with enriched U. The bulk of the particle consisted of material consistent with combustion of heavy fuel oil. Analysis of wind trajectories and particle dispersion model results show that the particle could have originated from a variety of areas across Asia. The source of such a particle is unclear, and the particle is described here in case it indicates a novel source where enriched uranium was dispersed.

[Ab] Resumo:Impact of the Fukushima Dai-ichi Nuclear Power Plant (FNPP1) accident on tritium ( H) and radiocarbon ( C) levels in the water column of the western North Pacific Ocean in winter 2012 is evaluated and compared with radiocesium ( Cs) data collected for the same region. Tritium concentrations in surface seawater, varying between 0.4 and 2.0 TU (47.2-236 Bq m ), follow the Fukushima radiocesium trend, however, some differences in the vertical profiles were observed, namely in depths of 50-400 m. No correlation was visible in the case of C, whose surface Δ C levels raised from negative values (about -40‰) in the northern part of transect, to positive values (∼68‰) near the equator. Homogenously mixed C levels in the subsurface layers were observed at all stations. Sixteen surface (from 30 in total) and 6 water profile (from 7) stations were affected by the Fukushima tritium. Surface and vertical profile data together with the calculated water column inventories indicate that the total amount of the FNPP1-derived tritium deposited to the western North Pacific Ocean was 0.7 ±â€¯0.3 PBq. No clear impact of the Fukushima accident on C levels in the western North Pacific was observed.

[Ti] Título:Anthropogenic Cs on atmospheric aerosols in Bratislava and around nuclear power plants in Slovakia.

[Ab] Resumo:Nuclear power plants (NPPs) have been one of the sources of anthropogenic radionuclides in the environment. This work combines the results from monitoring stations around NPPs in Slovakia (Mochovce and Jaslovské Bohunice) and academic measurements at the Comenius University campus in Bratislava. Most of the atmospheric Cs in this region come from the resuspension of the Chernobyl-derived Cs, as well as caesium produced during nuclear weapons testing. By comparison of the obtained results at NPPs with Bratislava data, radiation impacts of the NPPs on the local environments have been estimated to be negligible.

[Ab] Resumo:In this work, an advanced analytical procedure was applied to calculate radioactivity in spiked water samples in a close geometry gamma spectroscopy. It included MCNP-CP code in order to calculate the coincidence summing correction factor (CSF). The CSF results were validated by a deterministic method using ETNA code for both p-type HPGe detectors. It showed that a good agreement for both codes. Finally, the validity of the developed procedure was confirmed by a proficiency test to calculate the activities of various radionuclides. The results of the radioactivity measurement with both detectors using the advanced analytical procedure were received the ''Accepted'' statuses following the proficiency test.

[Ti] Título:Vertical distribution of Cs in grassland soils disturbed by moles (Talpa europaea L.).

[Ab] Resumo:Activity of biota is one of the factors influencing vertical migration of radionuclides deposited from the atmosphere onto the ground surface. The goal of this work was to study the vertical distribution of Cs in grassland soils disturbed by moles (Talpa europaea L.) in comparison with undisturbed grassland soils. Field observations and soil sampling were carried out in the areas of eight settlements in the Klintsovskiy, Krasnogorskiy and Novozybkovskiy districts of the Bryansk region, Russia in six years during the period 1999-2016. The study sites had been heavily contaminated by Chernobyl fallout in 1986. Activity of Cs in soil samples was determined by γ-ray spectrometry. Cs surface ground contamination levels at the studied plots (n = 17) ranged from 327 kBq m to 2360 kBq m with a mean of 1000 kBq m and a median of 700 kBq m . The position of the Cs migration centre in the soil in 2010-2016 was significantly (the Mann-Whitney U test, P < .01) deeper at mole-disturbed plots (median = 5.99 cm or 6.64 g cm , n = 6) compared to the undisturbed ones (median = 2.48 cm or 2.35 g cm , n = 6). The Cs migration rate at mole-disturbed plots (median = 0.26 g cm y , mean = 0.31 g cm y ) was significantly higher (by a factor of 3) than at undisturbed plots (median = 0.08 g cm y , mean = 0.10 g cm y ). The difference in the migration rates between the mole-disturbed and undisturbed plots (median = 0.18 g cm y , mean = 0.21 g cm y ) reasonably corresponded to the mass of soil that might be ejected by moles per unit area per year. The results of this study indicate that the burrowing activity of moles has increased vertical migration of Chernobyl-derived radiocaesium in the grassland soils.

[Ti] Título:Mapping potassium and thorium concentrations in Belgian soils.

[Ab] Resumo:The European Atlas of Natural Radiation developed by the Joint Research Centre (JRC) of the European Commission includes maps of potassium K and thorium Th. With several different databases available, including data (albeit not calibrated) from an airborne survey, Belgium is a favourable case for exploring the methodology of mapping for these natural radionuclides. Harmonized databases of potassium and thorium in soil were built by radiological (not airborne) and geochemical data. Using this harmonized database it was possible to calibrate the data from the airborne survey. Several methods were used to perform spatial interpolation and to smooth the data: moving average (MA) without constraint, or constrained by soil class and by geological unit. Overall, there was a reasonable agreement between the maps on a 1 × 1 km grid obtained with the two datasets (airborne data and harmonized soil data) with all the methods. The agreement was better when the maps are reduced to a 10 km × 10 km grid used for the European Atlas of Natural Radiation. The best agreement was observed with the MA constrained by geological unit.

[Ab] Resumo:A methodology of a preventive radioecological assessment of the territory has been developed for optimizing post-emergency monitoring and countermeasure implementation in an event of a severe radiation accident. Approaches and main stages of integrated radioecological zoning of the territory are described. An algorithm for the assessment of the potential radioecological criticality (sensitivity) of the area is presented. The proposed approach is validated using data of the dosimetric passportization in Ukraine after the Chernobyl accident for the test site settlements.

[Ab] Resumo:This paper provides research data on levels and character of radionuclide contamination distribution in the «sediments- water - plants ¼â€¯system of objects of the Semipalatinsk test site (STS). As the research objects there were chosen water bodies of man-made origin which located at the territory of "Experimental Field", "Balapan", "Telkem" and "Sary-Uzen" testing sites. For research the sampling of bottom sediments, water, lakeside and water plants was taken. Collected samples were used to determine concentration of anthropogenic radionuclides Sr, Pu, Am, Cs. The distribution coefficient (K ) was calculated as the ratio of the content of radionuclides in the sediments to the content in water, and the concentration ratio (F ) was calculated as the ratio of radionuclide content in plants to the content in sediments or soil.
