Cesium is vastly observed in nuclear wastewaters and is potentially considered a hazardous material, therefore, its removal from nuclear site wastewaters is an important task. Removal of radionuclides and heavy metals by phytoremediation is fast becoming attractive, due to its high efficiency and low cost. Furthermore, native plants, in terms of survival, growth and also reproduction under environmental stresses, have more stability than plants introduced from other environments. For phytoremedition purposes, it is essential to choose metal tolerant and accumulator plant species that are capable of contaminant transport and accumulation in a relatively short treatment time. In this research, the potential of Chenopodium album for phytoremediation of solutions contaminated with cesium was studied. Chenopodium album seeds were germinated in sand, and then one-month-old plantlets were transplanted in plastic trays containing nutrient solutions. Hydroponically grown plants were incubated in different concentrations of cesium chloride, representing 0.47, 1.58, 3.95 mgl
