Abstract

The abandoned uranium mines have adverse effect for the environment. The uranium deposit Harrachov-Rýžoviště is situated right in the Krkonoše National Park area. Especially the mobile hexavalent uranium U(VI) means the environment hazard. U(VI) may be easily adsorbed by colloids and by the mining water transported on the surface. Subsequent increasing pH-value mixing with the surface waters may cause higher mobility and contamination of stream sediments, soils and water resources. The gamma-ray spectrometry is suitable method for the detection of the U-anomalies in the field and laboratory variation for the determination of the U/eU ratio.
