During the mining and extraction of uranium, the principle means of protection measurement is to prevent uranium and its products diffusing into the environment. The main carriers of radioactive elements in the environment are air and water. Therefore, reduction of the pollution at a uranium mine can be achieved by the treatment of waste waters contaminated with ~(226)Ra. Radium contaminated waste waters represent a major biological risk. This paper presents the results of the study of the sorption of ~(226)Ra on active coal mechanisme and the influence of the physical and chemical characteristics of fluid. The ~(226)Ra removal from the residue pond water at the uranium ore processing plant was studied using eight types of indigenous active coals. The experimental results for each type of active coal and their effect on removal of ~(226)Ra from waste waters are presented in this paper.
