The article presents the distribution coefficient (Kd) values of 137Cs and 90Sr tracer radionuclides in solutions sodium calcium salts for a wide range commercially available inorganic sorbents: natural synthetic aluminosilicates, manganese, titanium zirconium oxyhydrates, phosphates, titanosilicates alkali metals, ferrocyanides transition metals. results were obtained using standard technique ...

Background: Man-made  radionuclides, which are present in environment, have been created by human activities and added to the inventory of natural radionuclides for example 3H, 131I, 129I, 137Cs, 90Sr and 239Pu, in spite of the amount added is little compared to natural quantities. The aim of this study is to estimate the levels of radiological doses in the soil samples collected from different...

background: the aim of this study was to measure137cs levels in soil and brick samples to set the baseline data and an indicator of fallout radioactivity for this part of the world. this study will help to probe, if there is any health threat posed by 137cs exposure to the residents of the area. materials and methods: twenty five samples of soil and 6 samples of bricks were collected from diffe...

The present situation of radioactive contamination at the village of Dolon and nearby villages such as Mostik, Cheremushka and Budene was investigated to serve as an aid to resolve dose discrepancy between model calculations and TL measurements made for external gamma-ray dose in air in Dolon. The paper was focused on the reevaluation of the accumulated levels and distribution of long-lived rad...

abstract background: measures to protect the public following an accidental release of radionuclides to the environment will depend on the circumstances including the extent of the potential hazards. the projected levels of risk are an important precondition in emergency planning. the levels can be expressed in terms of concentration levels in the environment or in foodstuffs. these derived int...

Natural radionuclides present in soil as well as certain anthropogenic radionuclides released to the environment are the major contributors to terrestrial outdoor exposures. In the assessment of human exposures from environmental radioactivity, besides the conventional method of soil and vegetation sampling combined with laboratory based analyses of environmental media, the other choice would b...

cesium content and some other more radiologically important mineral elements were measuredby nuclear and non-nuclear analytical methods in iranian daily diets.this study was extended to a few moresimilar functioning elements such as sr, rb, i, k, mg and ca as well. though the 137cs and otherradionuclieds were not measured in these diets under planned regular investigation in this work, but inco...

Deep water samples collected in 1963 and 1964 in the adjacent seas of Japan were analyzed radiochemically. Sr-90 and Cs-137 were detected in the deep layers down to 6,000 meters deep and showed approximately uniform vertical distributions below 1,000 meters. Mean concentrations of Sr-90 in deep waters were 0.028 ƒÊƒÊc/l in the Pacific and 0.035ƒÊƒÊc /l in the northern Japan Sea, and those of Cs...

The Hydrological Dispersion Module (HDM) of the RODOS (real-time on-line decision support) system for nuclear emergency management in Europe has been is developed at IMMSP, Kiev, Ukraine; NRG, The Netherlands; FZK, Karlsruhe, Germany; SPA “TYPHOON”, Obninsk, Russia; IPEP, Minsk, Belorussia, and NCSR “Demokritos”, Athens, Greece. Initial testing and customisation work was performed by NPPRI, Slo...
