Despite its enormous therapeutic potential, spa treatment is not always properly perceived, hence the numerous attempts to assess its effectiveness. In the world literature, there are few reports on therapy using sulphur- and radon-containing therapeutic waters. In countries with a long tradition of balneotherapy, activity in this field of medicine is evident. Undoubtedly, the interest in balneotherapy results also from natural resources used in spa medicine, which, as geological and balneochemical research shows, are enormous in Poland. A particular example of the occurrence of radon–sulphide waters, rare on the European scale, is the Przerzeczyn-Zdrój health resort. The mechanism of action of therapeutic waters is not fully explored, but their effectiveness in therapy is confirmed by many authors. It is believed to be an effect of combined action of many factors, the most important of which are thermal, mechanical, and chemical.
