Visitors seek the healing power of radon at strangely popular cave spa

The Gastein healing caves in the Radhausberg Mountain are extremely popular, notching around 75,000 visitors last year for their supposed healing properties. Of course, the healing properties in these Austrian caves and their water derive from radon gas, but some people claim it offers pain relief and can act as an anti-inflammatory for people suffering from joint pain. Now, the kind of medical personnel who don't live inside mountains like dwarves generally frown on bombarding people with radon, because it causes — what's the word? — oh right, cancer. But German and Austrian insurance companies will cover visits to the Gastein caves, and you know insurance companies always have your best interests at heart. [Source]
