Its Impact on the Environment. 1993 Uranium Institute Symposium Abstract Uranium Mining and Milling Sites Remediation - Its Impact on the Environment.
Hydrometallurgical processes used in uranium recovery have various environmental impacts.
This paper examines the radiological impact of resulting liquid and solid wastes. Since 1976 an environmental impact statement, including broad remediation concepts and subject to public enquiry, has been required by French mining regulators. Surveillance of sites is required until it is proved that environmental impact is acceptable. Mill tailings can lead to low rates of both internal and external exposure over long periods so monitoring after site remediation is required. The first stage of remediation is to make a complete inventory of all waste locations, types, characteristics, radiological impacts and relevant water flows.
