“…Since the physiological activity and organ development of plants, and the bioavailability of deposited radionuclides change with time, the T a ag value may greatly depend on the growth stage when a deposition occurs (Choi et al, 2005) Many researchers (Bunzl et al, 2000;Carini, 2001;Riekkinen and Jaakkola, 2001;Rosé n et al,1995;Strebl et al, 2002;Vidal et al, 2000) have investigated the aggregated transfer factor T ag mainly of radiocesium in natural and semi-natural ecosystems. However, almost all of these investigations were about the radionuclides deposited more than a year before the growth of existing plants.…”

“…As previous studies showed that the use of tillage techniques (disking and ploughing) in natural meadows led to a significant decrease in radionuclide transfer ( , ), these techniques were applied to all sites along with the addition of soil amendments. At some sites, a dose of fertilizer including potassium, nitrogen, and phosphorus minerals (NH 4 NO 3 + P 2 O 5 + KCl, NPK) and of lime was also added before the application of the amendments.…”

In situ remediation strategies are an alternative approach in the management of radioactive contaminated areas, especially when based on modification of soil properties by the addition of amendments. Here, this strategy is applied to reduce 137Cs and 90Sr soil-plant transfer in meadows from areas of Russia, Belarus, and Ukraine affected by the Chernobyl fallout. Meadows were established on podzolic and peaty soils. Amendments covered a wide range of materials, such as loamy and sandy soils, polygorskite clay, phosphorite, turf, and sapropel. Field experiments showed the poor efficiency of most of the materials: only the polygorskite clay provoked a notable reduction (1.5-2-fold) in 137Cs root uptake. Subsequent laboratory characterization showed the lack of significant changes in the radiocesium interception potential and soil solution composition in the amended soils, a fact that helped to explain the lack of effect on the reduction of transfer. Moreover, a laboratory methodology based on the quantification of the adsorption potential of the amendments and the reversibility of the adsorption process was applied. This methodology was first proposed for the correct selection of the suitable materials to be used to decrease radionuclide root uptake in future remediation actions and then validated with data of the previous field experiments.

“…One of the most important features of these isotopes is the ability to invariably adsorb (fix) the solid phase of the soil, leading to a decrease in soil motility and a decrease in plant accumulation. The combination of soil-chemical (crystal-chemical) reactions leading to a decrease in the mobility of radionuclides in the soil due to their entry into the interpackage spaces of secondary minerals is commonly called "aging" [31,37,41].…”

Object of research: to systematize (taking into account the possible consequences to biosphere) the known technologies for ecological restoration of soils contaminated by heavy metals and radionuclides. Only a healing technology should be recognized as one possible methodology for solving any soil problems. For soils contaminated by heavy metals and radionuclides healing patterns is conceptually ordered into the following levels: mission, strategy, technology. The mission of healthy soil should be aimed at maintaining the chemical elements content within the optimum interval. The strategy of healthy soil involves the regulation of individual elements content in the soil. Ex-situ a soil healing technology is implemented outside the original pollution site. In-situ, a soil healing technology is carried out directly on the original pollution site. Excavation of the contaminated soil layer is the first stage for ex-situ soil restoration. In the future it will be possible: 1) storage of contaminated soil at special landfills, 2) treatment of contaminated soil at a special reactor. All technologies for in-situ healthy of heavy metals contaminated soils can be ordered as: 1) localization, 2) deconcentration, 3) inactivation, 4) extraction.
