Toxic Health Spas? (sort of)
I found this over on boingboing:
Past tense health tech: radium baths, radon mine soaks
I guess people used to (and still do in some places) look to radiation and radon gas for health benefits. I remember when Lindsey and I bought our home a couple years back. There were all sorts of inspections you could have done on a house to make sure it was safe to live in, and one of them was a test for radon gas. One of the houses we looked at was having its radon test conducted while we were there. This reinforced in my mind the idea that radon is A Bad Thing. But it might cure arthritis, so lets go to Montanna.

“A half-dozen defunct gold and uranium mines south of Helena, Montana, attract ailing tourists, who bask in radioactive radon gas and drink radioactive water to improve their health.”
I guess this is one way to enforce natural selection.
you know, maybe we should go there….my hip has been bothering me recently
