Opis:: The authors have conducted research on radon occurrence in the groundwater system of Ślęża Massif in the Fore-Sudetic block. The research included documenting occurrence of radon waters in the granitoids of Strzegom-Sobótka Massif, buildingNWandWslopes of Ślęża. Among several springs flowing out from the granitoids and their waste, the Klasztorne Spring is characterized by constant radon (222Rn) concentration (306 ±39 Bq/dm3), but also constant though small discharge during the year, which enables estimating the admissible volume of this spring at 0.3 m3/h. The results obtained during the research show that this water can be treated as potentially medicinal. It generates the opportunity for the nearby town of Sobótka to develop as a health resort. Confirming the presence of radon groundwater in the granitoid part of Ślęża Massif implies a great probability that such w occur in the whole area of the Strzegom-Sobótka intrusion. It opens possibilities of recognizing new resources of potential therapeutic water and entails the necessity to take suitable actions for radiological protection of people living in this area.

Opis:: In Poland, the redox potential (EH) is seldomly measured in groundwater. Since the year 2006 determination of redox potential is required for documenting properties of curative mineral waters. Investigations of redox conditions in groundwater need both proper measurement and interpretation. In the paper, crucial questions of: 1) redox equilibrium in groundwater, 2) field measurement, 3) correction methods, and 4) EH interpretation are presented. Some aspects of applying the redox potential for interpreting groundwater chemistry and using geochemical modelling are illustrated by hydrochemical data of curative waters from spas in the Sudetes Mts., SW Poland. Main reasons of the common redox non-equilibrium found in groundwater are co-existence of numerous aqueous redox pairs and usually non-equilibrium in particular redox pairs. Redox determinations have to be done in the field, and require extreme cleanness and precision, e.g., measuring without contact with the atmospheric air. Field measurements must be corrected to the standard hydrogen electrode, considering: type of reference electrode, concentration of electrode filling solution, type of standard redox solution, and water temperature. The redox potential has been measured in water at first from all the Sudetic spas, totally in 33 water intakes. In curative waters from the Sudetes corrected EH ranges between –159 mV and +343 mV. Usually, thermal waters show lower EH values than cold, CO2-rich waters. The lowest redox potential was found in the hottest thermal waters, i.e., in water from Zdzisław intake (in Lądek Zdrój) and C-2 intake (in Cieplice Śląskie Zdrój). Generally, the higher the pH, the lower the EH in groundwater. Methods of geochemical modelling, which are often and often applied in groundwater research, also require the EH determination. Information about EH are used in the calculation of speciation models of water, and affect the results of whole geochemical modelling as well as evaluations of the saturation state. The speciation-solubility modelling for the Sudetic curative waters, presented in the paper, shows that the proper correction of field EH measurement determines the quality of calculations. Improperly corrected EH values might lead to species activity errors, even up to several order of magnitudes, and erroneous interpretation of the mineral phases stability in the hydrogeochemical system.
