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!

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.

perhaps an experiment has verbally controlled its inputs and outputs in analyzing the effect of an independant variable upon a dependant variable. this does not imply that that those inputs and outputs were actually controlled for , nor does it imply that any found correlations are inherently causative. between folk wisdom that kinda works vs. corporate advice that also kinda works but happens to make someone a huge profit ....... ill take the thermal baths first
Similar treatments exist without the radioactive water.
There are also old radon baths in Jachymov in Czech republic working on same principle. Exactly for same primary purpose - problems with joints and bones.

Then communists made local uranium mines/gulags for 'enemies of the state' which was basically a prolonged death sentence, many were just beaten to death or died from cold/starvation.

Ah, yes, radiant skin.

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...

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.
The abstract indicates 6 fractions (so 0.5Gy for each). And 3 is low compared to cancer treatments, which go up to 80 Gy.
Gray (Gy) - measures energy deposited per kilogram of tissue. Think of it like measuring how many bullets hit a target, not how much damage they do.

Sievert (Sv) - measures biological damage. This accounts for the fact that different types of radiation and different tissues react differently. Think of this as the actual damage done.

The bullet's energy is identical in all cases (same Gy), but the biological damage varies wildly (different Sv).

The same energy deposited (Gy) causes vastly different biological damage (Sv) depending on:

What tissue (bone marrow is like your heart - critical; muscle is more resilient)

What radiation type (alpha particles are like hollow-point bullets - more damaging per energy unit; gamma rays are like full metal jacket - cleaner pass-through)

For most medical purposes (X-rays, gamma rays), 1 Gy is approx 1 Sv, which is why people use them interchangeably and add to confusion.

Location and delivery matter enormously. It's like pouring water. Put 3 liters in your lungs, you drown (dead). Put 3 liters on your hand, your hand gets wet (annoying but harmless).

3 Gy to your whole body at once is potentially fatal. You'll likely die within weeks from bone marrow failure, your blood cells can't regenerate. 3 Gy to a small tumor in your knee is a typical treatment session. The rest of your body gets almost nothing, and your bone marrow keeps working fine. 3 Gy spread over 6 sessions (0.5 Gy each) to a localized area is a very low dose that gives tissue time to repair.

For a moment I was confused that radiation doses would be measured in gigayears.
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.

Radon girls anyone ? /s

This might be one of those cures that works like the old T-Gel shampoo (ie: carcinogenic coal tar that turned out to be immune-suppressing enough to prevent dandruff eventually caused cancer).

Though, at the ages when Osteoarthritis shows up, it might be better to take on a smaller risk of monitor-able extremity cancer than the pretty large QoL reduction of severe arthritis.

That's not why coal tar works.

Coal tar is technically carcinogenic, yes, but no study has found any association with cancer when used topically in low doses [1].

Coal tar's mechanism of action is thought to be carbazole, an aryl hydrocarbon. It is assumed to work through binding to the aryl hydrocarbon receptor, a relatively newly discovered immune cell regulator. Tapinarof (Vtama) is a new medication that also works on ArH and is really effective at reducing inflammation.

Coal tar was also used together with UVA light and psoralen (a light-sensitizing medication) to treat skin diseases like psoriasis, a protocol called Goeckerman therapy that's no longer commonly practiced. This combination does carry the risk of cancer, but it's probably due to the UVA and not the coal tar.

The age-related risk is an excellent comment. There are illnesses that progress slowly, and the age should always be taken into account when going for a cure.

I am in my 50s and wonder from time to time what I would do if certain health-related events strike. For some, I have a well-defined solution (such as suicide for Alzheimer or ALS; or an active cure for cancers that have a fair chance of being fought). The more problematic ones are the ones fatal in long(er) term, with an aggressive and diminishing cure.

I am offering my basement as a Radon spa. Anyone interested?

Dose can be controlled by switching off the forced ventilation and sealing the gas trap.

Glad to see this! We need better treatments for OA short of a joint replacement.

I'm not too surprised that this treatment works. It's essentially like localized steroids to just the joint- killing off the immune cells causing inflammation.

Good features is that it's localized (so no systemic immunosuppression) and the risk of cancer is low since you rarely get radiation-induced cancer in joints because there's not enough dividing cells. Unfortunately heading to radiotherapy is a logistical challenge, but there are enough people suffering from OA that would happily do this to get relief.

I'd much more prefer allogeneic stem cell treatment for osteoarthitis. It's a shame it's not available in all those countries where millions of dollars are made by companies making knee joint replacement prosthesis. What a coincidence.
stuck in cloudflare for 3 seconds so i cancelled loading the website

why to web admins think this is acceptable for visitors?

This should be a reminder that we have no evidence that the Linear no threshold model of radiation exposure is accurate. In fact, we have compelling evidence against it. But due to rather aggressive lobbying effort by anti-nuclear activists, we are stuck with this idea for the time being.

It's simply the default that was decided on as the most conservative option possible, but that's pretty much it.

Radioactive baths have a rather long pedigree. In Jachymov, Czech Republic, they are used for over century. Sometimes they are even covered by health insurance.

How soon will some entrepreneur open a spa in Chernobyl?
A recent Peter Attia Drive podcast has an interview with Dr. Sanjay Mehta, a radiation oncologist who has recently also started using low-dose radiation to treat arthritis. Empirically the results seem quite encouraging.

Exposure to radiation up-regulates genes involved in DNA repair pathways, genes associated with antioxidant defense (notably those downstream of the Nrf2 transcription factor) and autophagy-related genes (which are crucial for the degradation and recycling of cellular components).

Fasting does all those things, too -- without introducing random errors into one's DNA. Basically everyone under 40 should do regular fasts of some form, and those that do will probably derive no additional benefit from exposure to ionizing radiation, i.e., the type of radiation being promoted by the OP. (People older than 40 need to worry about losing muscle mass during a fast since old people find it very hard regain muscle mass once it it lost. Actually it is likely that only people over 60 or 65 might have to worry about muscle mass: experts disagree on the best cut-off age, and 40 years old's is the lowest I have seen.)

Three days of fasting has all of the benefits I list above, but there are risks to going completely without calories for that long, and actually our ancestors probably went without any access to calories for days almost never, but often endured stretches of days in which their calorie intake was less than a sustainable level, but not zero. To reduce the risks of going completely without calories for 3 days at a time, longevity researchers have devised the "fasting-mimicking diet", which give over the course of 5 days most or all of the benefits as eating no calories at all for 3 days. It restricts calories to about 800 calories per day with only 10% of that coming from protein and is the type of fasting that most people should be doing.

FMD requires no interaction with or prescription from the health-care industry and costs nothing except the time and attention needed to learn how to count calories if one has never done that before.

> Basically everyone under 40 should do regular fasts of some form,

I'm extremely sceptical of claims of the form "basically everyone in [broad group] should do [medical intervention]", but you sound knowledgeable. Could you share your evidence, please?

Two key caveats: 40% of people said their arthritis got better with the placebo treatment, while 70% got better with the radiation. Yes, that's clearly a difference, but it also means that 40% of people don't need to expose themselves to the side effects of radiation in order to get relief from their arthritis. Second, the realy number of people who don't need radiation is actually higher, because this study limited the use of NSAIDs like ibuprofen (Advil) or naproxen, which would probably have helped a lot of the other people. Granted, for people who can't take NSAIDs because of kidney disease or something, maybe this will be an option in the future, but I really want to see the long-term safety data before I go irradiating everyone's knees.
UV doses sufficient to cause erythema, mild sunburn, will trigger programmed apoptosis(programmed cell death) and if you don't have some other sensitivity to UV and do have psoriasis (another chronic autoimmune disease) after the sunburn has subsided you can get substantial reduction in the size and severity of skin lesions in many cases. The reset can sometimes last for awhile. This is well known and is the basis for natural (sun) and medically administered (uvb light) treatments.

In no way is UV caused DNA damage good for a person in any dose. The effectiveness of this treatment has nothing to do with vitamin D generation or hormonal changes as far as I know. You have to damage your skin to somehow reset the immune system and get the result. It is a bargain with the devil as I think are many radiation based therapies. That doesn't mean they aren't useful.
