Zusammenfassung:The investigation of the radiation situation is an essential part of preparing the remediation of the formerly abandoned Wismut sites. If the exposure is relevant, then the exposure pathway “inhalation of radon/radon daughters” plays the dominant role. Therefore, the development of a straightforward approach suitable for the evaluation of the involved radon situation is one of the most important tasks. It has to include the whole chain beginning with the characterization of the relevant exposure situation and ending up with the identification of remedial options. For that purpose a new technique of visualizing the radon flux from the waste rock dumps has been developed. The specific conditions at formerly abandoned Wismut sites will be demonstrated and the remediation solutions envisaged to reduce the radon flux will be explained.
