Abstract: Environmental uranium contamination based on human activity is a serious problem worldwide. Soil contaminated with uranium poses a long-term radiation hazard to human health through exposure via the food-chain and other pathways. This chapter is an overview of processes and modern techniques for remediation of soils contaminated with uranium, with special attention on phytoremediation. Phytoremediation takes advantage of plant to extract, sequester pollutants in soil, water, and air with an aim of pollutant removal and transformation into harmless forms. The objective of this chapter is to develop a better understanding of plants behavior and the degree of affinity towards the adoption of uranium for hyperaccumulators plants based on review of international research. To understand the mechanism of uranium uptake in plants and accumulation, a necessary prerequisite is the application of radiophytoremediation on the ―real‖ scale.
