ABSTRACT
Radioactivity in extraction and processing represents the most dangerous works involving important risks and a high pollution potential on the environment. The most important ways of radioactive element transportation in the environment are air and water. For these reasons, the most important factor for reduction of the pollution at the uranium mine is waste water contaminated with 226Ra. Radium contaminated waste waters represent the major biological risks. The present paper study the sorption mechanism of 226Ra on activated carbons and the influence of the physical and chemical characteristics of the support and the fluid. 226Ra removal from pond water at the uranium ore processing plant using eight types of indigenous activated carbons has been studied and results are presented in this paper. The paper presents tables and graphics with experimental results for each types of activated carbon and their removal from waste waters.
