Soil to plant transfer of 238U, 226Ra and 232Th on a uranium mining-impacted soil from southeastern China

Radioecological characterization of a uranium mining site located in a semi-arid region in Brazil

“…According to Chen et al (2005) there are considerable differences in the uptake and translocation of long-lived radionuclides among different plant species. Up until now, several investigations on mobilization of natural radionuclides (such as 238 U and 226 Ra) in different compartments (soil, plant, and water), as well as the transfer between them, have been performed at different uranium mining sites around the world.…”

Analysis of Remediation Strategies for Radionuclide-Contaminated Soils in Uranium Mining

“…For example, in southeastern China, soil-to-plant transfer of 238 U, 226 Ra and 232 Th were studied in nine different plant species; it was found that root-uptake of each radionuclide was plant-specific (Chen et al 2005.) Often conducted to predict Ra entry into the food web, this type of research is also valuable in evaluating whether phyto-remediation may be a feasible option for cleaning 226 Ra-contaminated soils on U mine sites.…”

Uptake of Some Toxic Elements by Wild Plants in Siwaqa Area/Central Jordan

“…This ability also allows plants to accumulate other non-essential elements which have not known biological function (Djingova & Kuleff, 2000). Several studies have been carried out to evaluate and describe The accumulation of toxic trace elements and its impacts on the plant diversity were investigated by many authors and in different regions (Chen et al, 2005;Tomé et al, 2002). The soils and plants contain all naturally occuring radioactive elements with half-lives comparable to the age The wide distribution of redox-sensitive elements (RSE) as arsenic (As), cadmium (Cd), selenium (Se), and strontium (Sr) in the top soil of Siwaqa area are related to the weathering action of alkaline surface and groundwater on the parent rocks.…”
