Śnieżnik metamorphic unit - Opis:
- 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 of 222Rn 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 of 222Rn release from groundwater through surface waters into the atmosphere. Perhaps this process can be described with a universal mathematical function.
