For centuries, in Bulgaria, since Roman times, people have been bathing in slightly radioactive water to treat osteoarthritis. I'm not sure how this is news or an invention when it's been around for centuries and has been the standard of care in Bulgaria for decades. There are sanatoriums and spa centers in Pavel Banya, Bulgaria [0], and I know many friends who go there once or twice a year for treatments and swear they couldn't live without them!

3 Gy is nowhere near what could be qualified as a "Low dose".

"A whole-body acute exposure to 5 grays or more of high-energy radiation usually leads to death within 14 days. LD1 is 2.5 Gy, LD50 is 5 Gy and LD99 is 8 Gy.[11] The LD50 dose represents 375 joules for a 75 kg adult. " https://en.wikipedia.org/wiki/Gray_(unit)#Radiation_poisonin...

Depending on the field, 3 Gy IS 'small' (with respect to doses to tissue during cancer treatment, which can be 60 Gy). Whole body doses of 1 milliGy in the environmental biz are considered worth examination. Even investigations of biomarkers for radiation exposure typically use doses in the range of 3 Gy.

Just because something has been done for hundreds of years does not mean it has been scientifically shown to actually do more than placebo. A lot of people do a lot of stuff that has been proven to do nothing detectable, and they still swear by it.

"It has been done for hundreds of years" isn't a good argument. There is a reason "Appeal to tradition" is one of the more famous logical fallacies.

Also: The radiation doses used in this trial are very likely much, much higher than what you would get from such a bath in radioactive water (otherwise the water would be so radioactive that staying in there or even drinking it would kill you very quickly), so this doesn't really tell us anything about whether the traditional modalities do anything or not. And yes, stuff like that also exists in Austria with Radon caves, and many other places.

Gy has a mass component to it. Is 3Gy on just your joint different to 3Gy of your whole body?

A gray is a measure of energy deposition per unit mass. 1 Gy to the entire body is very different than 1 Gy to a particular part of the body, especially since some parts of the body are far more sensitive to radiation than others.

Similar treatments exist without the radioactive water.

The abstract indicates 6 fractions (so 0.5Gy for each). And 3 is low compared to cancer treatments, which go up to 80 Gy.
