In the years 2020-2022, the authors conducted research on the activity concentration of 222 Rn in the groundwater of the eastern part of the Izera metamorphic unit. As a result, they found potentially medicinal radon waters in hornfelses of the eastern part of the Szklarska Poręba band. The value measured in one of the water samples appeared to be the highest activity concentration of 222Rn in groundwater of Poland so far - 3368 ±61 Bq/dm3. The authors also found that outflows of potentially medicinal radon waters account for almost 85.5% (47 out of 55) of all groundwater outflows in the study area. Thanks to the large amount of data obtained, the authors calculated a new value of the hydrogeochemical back-ground of 222 Rn in the groundwater of the Izera metamorphic unit. The background is currently 17-890 Bq/dm3. In Poland, higher values have only been reported of the Lądek-Śnieżnik metamorphic unit. The research results also open the way to the possible creation of a modern radon spa in Szklarska Poręba. It could operate in Biała Dolina on the basis of both previously found resources of radon waters of the Karkonosze granite and the radon waters forming within the eastern part of the Izera metamorphic unit.

The authors conducted studies on the release rate of 222Rn from groundwater flowing out of a spring, from metamorphic reservoir rocks. This source gives rise to a stream about 205 m long. The activity concentration of Rn in the spring was about 700 Bq/dm33, took place at a distance of about 1 70-180 metres from the spring. With regard to the waterflow path, flowtime and the volume of water flowing through the cross-section of the tested stream, the exhalation coefficient of222Rn from water to atmospheric air is 3.80 Bq/dm3/m, 1.51 Bq/dm3/s and 1. 25 Bq/dm3/dm3, respctively. According to the authors, further research conducted in other springs occurring in other types of rocks and under different flow conditions (at different times of the year) will allow characterizing the dynamics of the process of222Rn release from groundwater through surface waters into the atmosphere. Perhaps this process can be described with a universal mathematical function.

W artykule przedstawiono wyniki badań stężenia radonu w wodach podziemnych na wschód od Strzegomia w rejonie masywu granitoidowego Strzegom-Sobótka. Pomiary wykonywano w Laboratorium Hydrogeologicznym na Wydziale Geoinżynierii, Górnictwa i Geologii przy użyciu ultraniskotłowego spektrometru ciekłoscyntylacyjnego Quantulus 1220. Uzyskane wyniki wyniosły od 0,9 do 288,5 Bq/dm3. Wartości stężenia radonu większe (lub równe) niż 74 Bq/dm3, oznaczające minimalne stężenie radonu, które powoduje korzystne oddziaływanie dla organizmu, zanotowano jedynie w próbkach wody pobranych ze wsi Wiśniowa.

The paper presents results of researches of radon concentration in the groundwaters to the east of Strzegom in the granitoid Strzegom-Sobótka massifs region. Measurements were performed in the Hydrogeology Laboratory on Faculty Geoengineering, Mining and Geology with the use of spectrometer Quantulus. Measurements to oscillate between 0.9 to 288.5 Bq/dm3. Concentrations of radon higher than or equal 74 Bq/dm3 - minimum concentration of radon which are cause beneficial to human body were registered in water samples with Wiśniowa.

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.
