Development of nuclear technology, mining, nuclear fuel cycle, and military operations are the most important reasons of radionuclides entrance to the environment. Transmission of soil radionuclides into the food chain is a major threat to human health in the long term. Therefore, removing these pollutants from the soil is extremely important. Phytoremediation is a simple and economical method that uses green plants to reduce or eliminate different types of soil pollutants. This technology is very practical and environmentally friendly. In this study wheat and sunflower plants were used to remove radium from soils of Saghand and Bandar Abbas mine's districts. Moreover, the effect of different concentrations of citric acid on the accessibility of plants to this element was investigated. In general, sunflower had better efficiency in radium absorption from soil of Saghand. In the case of Bandar Abbas soil, the amount of absorbed radium was more using sunflower plant, but more differences were observed in radium absorption by wheat plant at different concentrations of citric acid.
