[en] More than 130 mine dumps of abandoned and working mines in Baden-Wuerttemberg were recorded, radiometricly measured, evaluated and some of them sampled. The representative selection of the mining activities resulted in the fact, that most of the dumps belonged to old and smaller residues of the lead/zinc and iron ore mining. In addition all existing mine dumps from the uranium exploration in Baden-Wuerttemberg and Bavaria were investigated. The highest doses, up to 10 rem/a, were found on the piles of the uranium exploration. These actually supervised and licensed depositions are followed by the old uncontrolled mine dumps of the Wittichen mining area with doses up to 2 rem/a. The numerous porphyry and granite quarries show doses between 0,1 and 0,2 rem/a. The lowest doses were found on the dumps of the hydrothermal Pb/Zn and iron ore deposits, while the slag piles of the ooelitic iron ore processing showed high Thorium anomalies. The Ra-226 and Pb-210 analyses of the deposited materials confirmed the radiometric results. The analysis of seepage and gallery waters showed only a small number of values exceeding the derived drinking water concentrations. (orig.)
