Probably just Tritiated water which is essentially harmless. Basically water with extra neutrons and it is very weakly radioactive. So weak that you can't detect it with a Geiger counter. Since it is water it does not accumulate in organisms. Tritium is also naturally created in the atmosphere by cosmic radiation.

That's exactly what it is - which is why the comment above is so profoundly dishonest.

You can buy tritium on Amazon - it's harmless.

Please, could you explain why US, EU and Canada governments have set narrow legal upper limits for Tritium presence on drinking water if is soo totally harmless? Are being those governments dishonest or stupid?

And why those dishonest physicians recommend "extended strong medical/therapeutic intervention" [1] in some cases of accidental exposure to Tritium?

If you define the qualities of a chemical by the stuff sold on Amazon prepare yourself for a nasty surprise when meeting the real deal.

There's been so few serious Tritium exposures in humans so we don't know how much it would take to cause serious harm in humans. There have been some limited studies done on things like yeast and mice which suggest you'd have to ingest an extreme concentration of it to see increases in cancer rates.

NRC regulates and monitors tritium spills quite actively. Here's an excerpt from their page on Tritium: https://www.nrc.gov/reading-rm/doc-collections/fact-sheets/t...

> As an example, drinking water for a year from a well with 1,600 picocuries per liter of tritium (comparable to levels identified in a drinking water well after a significant tritiated water spill at a nuclear facility) would lead to a radiation dose (using EPA assumptions) of 0.3 millirem (mrem). That dose is:

- at least 2,000 to 5,000 times lower than the dose from a medical procedure involving a full-body CT scan (e.g., 500 to 1,500 mrem from a CT scan)

- 1,000 times lower than the approximate 300 mrem dose from natural background radiation

- 50 times lower than the dose from natural radioactivity (potassium) in your body (e.g., 15 mrem from potassium)

- 12 times lower than the dose from a round-trip cross-country airplane flight (e.g., 4 mrem from Washington, D.C., to Los Angeles and back)
