Abstract: The paper deals with the development of a highly sensitive method for determining plutonium isotopes (238Pu, 239Pu + 240Pu, 242Pu) in the solid samples of environmental objects with preliminary radiochemical preparation. The chosen conditions for preparation of samples permit effective separation of plutonium from mixing alpha-radiating radionuclides and allow plutonium to release in the radiochemically pure form to a sample to be calculated. Spectrometric measurements of the calculated samples and identification of isotopes were made on a “Progress-alpha” alpha-spectrometric unit having a silicon semiconductor detector. The developed procedure is rather reliable in identifying and estimating the content of major plutonium isotopes in the soil and bed deposits at their background values (1 Bc/kg or higher). The paper presents the results of analysis of samples of the soil selected during radioecological monitoring in the South-Western Okrug of Moscow, as well as the alpha-spectra obtained.

Uptake of radioactive and stable Co and Zn isotopes by barley plants under mixed radioactive and chemical contamination of soils (English available)

Reference: Eurasian Soil Science, 2010

ISSN: 1556-195x

DOI: 10.1134/S1064229310030130

Keywords: co, zn, soil, plants, podzolic soil, chernozem, isotope

Abstract: The effect of Co and Zn on the accumulation of 60Co and 65Zn by plants was studied in experiments with growing barley on a soddy-podzolic soil and a chernozem containing the radionuclide and increasing concentrations (from the background level to a high degree of contamination) of the corresponding metal. The root uptake of 60Co was directly related to the soil contamination with Co and its accumulation in the plants, while an inverse relationship was observed between the activity of 65Zn in the plants and the content of Zn in the soil. It was concluded that the transfer of the radionuclide into the plants under mixed radioactive and chemical contamination depended, on the one hand, on the mobile reserve of the stable nuclide in the soil and the solid phase potential to release its ions into the soil solution and, on the other hand, on the requirement of the plants for this element and the uptake rate of its ions by the roots from the solution.

Abstract: The article presents data concerning the migration of cesium-137 in the chain “soil – plant (feed) – the bird – products (meat)”, as well as limits of acceptable content of radionuclides in feed and permissible contamination of pastures for waterfowl. Suggests ways to reduce the concentration of cesium-137 in the organism and meat of poultry by applying sorbents and culinary processing, which are successfully implemented in conditions of radioactive contamination from the Chernobyl disaster.

METHOD FOR DECONTAMINATING SOIL CONTAMINATED WITH HARMFUL MATERIALS

Author: ABEL Albert E.

DOI:

Keywords: plutonium, uranium, decontamination

Abstract: Soil decontamination. SUBSTANCE: soils containing sand and clay contaminated with nuclear wastes, elementary mercury, or mixed wastes including harmful organic compounds are decontaminated by treating them with water-free liquid ammonia or ammonia combined with solvated electrons. Methods include concentration of radionuclides such as plutonium and uranium in soil and clay corpuscles to obtain residual product that does not practically contain pollutants thereby enabling soil recultivation. Ammonia liquids such as water-free liquid ammonia facilitate decontamination due to reducing soil to fragments (corpuscles) to obtain finely dispersed substances wherefrom mercury droplets are extracted. High density of mercury makes it possible for soil particulates to settle down and mercury is separated from soil particles. EFFECT: reduced space requirement and expenses for contaminated soil storage. 37 cl, 3 dwg

Abstract: Investigation of changes of soil contamination, according to time, of the Belgorod region contaminated by radionuclide emissions of Chernobyl. The average velocity distribution of the radionuclide cesium-137 into the soil was found to be 3 mm / year. It is shown that over time, the radiation situation in the most contaminated after the Chernobyl nuclear power plant is gradually stabilizing.
