Radon is used for therapeutic purposes in the form of baths and inhalations. As with any medical treatment, the advantages and disadvantages for patients should be carefully weighed up by doctors.

During a radon cure, patients are exposed to a high concentration of radon for a short period of time in order to relieve pain, increase mobility and thus reduce the need for medication for a longer period of time.

There is evidence that radon cures lead to a significant improvement in the general condition of certain diseases. Radon cures are mainly used for rheumatic diseases. These are chronic inflammatory diseases of the joints or spine, such as ankylosing spondylitis, or chronic degenerative diseases of the joints or spine, such as arthrosis.

A radon cure should only be undertaken if it is medically necessary. It must be clarified how the advantages (pain relief, reduced need for medication) are to be assessed in relation to the disadvantages (slightly increased risk of lung cancer). It is up to the treating physicians to weigh up the benefits against the risks. In principle, such a clarification must be made for every medical treatment (e.g. for medication and its contraindications).

Radon applications for wellness purposes are not recommended.
