well actually not all radon therapy is by inhalation. One study was in radon water by soaking the joints and no inhalation occurred. SO the radon rich air is not the answer as to why we see benefits.
Remember AS was put into total remission in the 1950's in Germany through the use of radiation. Unfortunately the leukemias that resulted were ugly and the doses were too high.
