Radon is used for therapeutic purposes in the form of tub baths and inhalations. As with any medical treatment, the advantages and disadvantages should be weighed against each other.

There are a number of indications that a radon cure can lead to a significant improvement in the general condition of some diseases. This applies, for example, to rheumatic diseases. It must be clarified how the advantages (pain relief, lower consumption of medication) are to be assessed against the disadvantages (slightly increased risk of lung cancer).

In principle, such a clarification must be made for every medical treatment (for example, for drugs and their contraindications). It is the responsibility of physicians to consider the justified indications of such forms of therapy for their patients.
