Oddly, Radon therapy does seem to show some significant long term benefit for arthritis. [https://pubmed.ncbi.nlm.nih.gov/14673618/ https://pubmed.ncbi.nlm.nih.gov/14673618/] God knows why - maybe the bodies natural healing mechanisms when dealing with low level radiation reduces the inflammation? Or short term spike, causes longer term downregulation?
