About the report
Our study highlights that the results of radon exhalation studies are vitally dependant on the selection of individual survey points. We suggest the use of a randomised system for both, the selection of survey points and the placement of charcoal canisters at each survey point, to avoid over estimation of the radon exhalation fluxes. In addition, our study underlines the importance of having reliable pre-mining radiological data available to assess the success of rehabilitation of a uranium mine site.
