The remediation of radionuclides from the environment is important for human health because the emitted ionizing radiation affects people by depositing energy in the body tissues. In this way, larger doses can cause extensive cellular damage and result in cell death. But even low levels of radionuclides in chronic exposure are considered to produce genetic effects, precancerous lesions, benign tumors, cataracts, skin changes and congenital defects. A phytoremediation study was performed on old uranium mill tailings waste depot of a former uranium ore reprocessing factory in South Bohemia. The objectives of our work were to: (i) perform a geobotanical study of the plants growing in this area; (ii) determine the distribution of 226 Ra among selected plant species; (iii) carry out the biomonitoring of recultivated areas; (iv) test the low contaminated site for production of non-food plants and (v) propose the mechanism of clean-up of water contained u-ranium and 226 Ra.
