Keywords: Soil to mushroom transfer, 137Cs, 40K, Alkali–alkaline earth elements, Heavy metals
Abstract: The present work is devoted to an investigation on the soil to mushroom transfer parameters for 137Cs and 40K radionuclides, as well as for some stable elements and heavy metals. The results of transfer factors for 137Cs and 40K were within the range of 0.06–3.15 and 0.67–5.68, respectively and the most efficiently transferred radionuclide was 40K. The TF values for 137Cs typically conformed to a lognormal distribution, while for 40K showed normal distribution. Statistically significant correlations between 137Cs soil to mushroom transfer factors and agrochemical soil properties have been revealed. Although the concentration ratios varied within the species, the most efficiently transferred elements seems to have been K, followed by Rb, Zn, Cu, Cd, S, Cs and Hg.

Title: First measurements of 238Pu and 238Pu/137Cs activity ratio in Montenegro soil
Author: Nevenka M. Antovic, Perko Vukotic, Nikola Svrkota, Sergey K. Andrukhovich
Reference: Journal of Radioanalytical and Nuclear Chemistry , July 2012, Volume 293, Issue 1, pp 299-302
DOI: 10.1007/s10967-012-1661-x
Keywords: 238Pu activity, 238Pu/137Cs ratio, Soil, Montenegro
Abstract: Plutonium-238 (238Pu) activity concentrations in soil samples from Montenegro (six samples from three localities) have been measured for the first time. The 238Pu/137Cs activity ratio was determined on the basis of alpha and gamma-spectrometric measurements, and found to be with an average of 0.0006 and standard deviation of 0.0003. By using the activity ratios determined in the present study, 238Pu activity concentrations were estimated for three localities in the central: one in the northern, and two in the eastern part of Montenegro.

Title: Study on the rate of plutonium vertical migration in various soil types of Lublin region (Eastern Poland)
Author: Jolanta Orzeł, Andrzej Komosa
Reference: Journal of Radioanalytical and Nuclear Chemistry, January 2014, Volume 299, Issue 1, pp 643-649
DOI: 10.1007/s10967-013-2774-6
Keywords: Plutonium isotopes, Alpha spectrometry, Migration rate, Soil profile
Abstract: Soil contamination level with 239+240Pu of Lublin region was determined using the alpha spectrometric method. Results were compared with similar data from the study performed 15 year earlier. Decrease in total 239+240Pu concentration and reducing quantity of Chernobyl fraction (up to almost negligible value of 1 %) has been observed in upper soil layer. Determination of 239+240Pu concentration in soil profile layers allows calculating a vertical migration velocity of plutonium applying a compartment migration model. It was found that 239+240Pu migration rate varies depending on soil type from 0.29 cm year−1 in Podsols to 0.58 cm year−1 in Fluvisols with mean value of 0.5 cm year−1.

Title: On peculiarities of vertical distribution of 239,240Pu, 238Pu and 137Cs activity concentrations and their ratios in lake sediments and soils
Author: B. Lukšienė, E. Maceika, N. Tarasiuk, E. Koviazina, V. Filistovič, Š. Buivydas, A. Puzas Reference: Journal of Radioanalytical and Nuclear Chemistry , February 2014
DOI: 10.1007/s10967-014-3026-0
Keywords: 238Pu, 239,240Pu, 137Cs, Origin, Lake sediments, Upland and flooded soils, Vertical profiles
Abstract: Distributions of 239,240Pu, 238Pu and 137Cs activity concentrations in the cores of sediments in the shallow lake, flooded and upland forest soils taken in the vicinity of Vilnius city were analyzed. The radiochemical, α-spectrometric and mass spectrometric methods were used for the plutonium evaluation and γ-spectrometry was used for the radiocesium evaluation. The only peak of enhanced radionuclide activity concentrations was determined for the lake bottom sediments, whereas vertical profiles of the radionuclide activity concentrations in flooded and upland forest soil cores were distinguished by two peaks. The obtained values of the activity concentration ratio 238Pu/239,240Pu and the isotopic ratio 240Pu/239Pu indicated that the global fallout was a source of plutonium in the investigated environment. Chernobyl-derived radiocesium was detected solely in the surface layers (2–11 cm) of the studied sample cores. The contribution of the Chernobyl deposits amounted to about 2.26, 6.11 and 20.9 % of the total radiocesium inventory in the bottom sediments, the upland soil and flooded soil, respectively.

Keywords: polyion complex, decontamination of surface soil, suppression of dust release, Iitate-mura, upland field in a plastic greenhouse, pasture, paddy field, radioactive cesium
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.

Abstract: The method of cleaning consists of infusion of chemical materials into the soil. Topsoil is covered by limestone or dolomite flour (5-6 tons per hectare), with potash KCl, KNO3 or KMgCl 3.6 H2O in an amount of not less than 200 kg per hectare. This process is followed by plantation of mixture of perennial grasses, which are mowed in autumn and placed in storage, precluding the migration of radionuclides.
