What is radon?

Radon is a naturally occurring radioactive noble gas, found throughout the earth's crust and in the air, but in varying concentrations in different regions. If spring water is only surrounded by radon in the ground, it may contain radon as well. Medicinal water containing radon is one of the most effective remedies in the field of balneology. The medicinal water from the Martin spring in the Menzenschwand valley, which contains radon, has been used for therapeutic purposes since 2005. For water containing radon to be recognised as medicinal water, a minimum concentration of 666 Bq/l is required.

Radon222 stimulates the immune system, stimulates the formation of tissue hormones, which have an anti-inflammatory and therefore analgesic (pain-relieving) effect. Medicinal water containing radon has been shown to be particularly effective in the treatment of rheumatic diseases, but also in the treatment of respiratory tract and skin diseases.

The springs of the Radon Revital Bad are located in the Krunkelbach valley. Two boreholes in the granite of the Feldberg Massif provide the water for the pool on the one hand and for the radon baths on the other. The piping, storage and supply system as well as the water quality are subject to monthly inspections by an independent, certified and accredited testing laboratory. Since 2006, the Radon Revital Bad has held the licence to manufacture radon as a medicine for humans. The company carries the certificate of good manufacturing practice issued by the German Drug Regulatory Authority.
