Strontium 90 has a half-life of about 30 years, so if you can see it, it was made within the last 300 years (it takes about 10 half-lives for an isotope to become very, very hard to detect). if you detect Sr90 it is not natural, it had to have been made by us, somewhen. Same with Cs137, it’s not natural. Most likely source is Chernobyl.

Modern gear can detect a few atoms of a radioactive substance.

You’re right, we should trust the governmental scientists who feed the MSM their conclusions. They don’t have any self-interest or benefit in an intended outcome, and, there’s plenty independent, 3rd parties who give us reports and double-blind proofs, etc. Sarc off. Please let’s all worship the EPA while we’re at it.

You are suggesting a different half life for Sr90?

It is true that EPA will lower their “standards” for a chemical if the analytical gear improves and you can “see” lower quantities.

The article says “100 times some limit” for H3, but I did not see where they mentioned Sr levels at all, just that they detected it.
