The same happened after the Three Mile Island meltdown.

Huge amounts of radioactive krypton gas were "vented", and, being much heavier than air, it all ran downhill and pooled invisibly at the nearest dam where, conveniently, only poor people lived. No effort was expended to warn or evacuate them, or to catalog the deadly maladies they suffered in their thousands afterward.

To this day it is easy to find people insisting in all earnestness that TMI didn't kill anybody. They are never interested in discussing the gassing of the downstream population.

That's highly outside the norm of scientific understanding on TMI. Please provide a citation suggesting the dose and dose rate that you think those downwinders received. I can help compare dose rates to expected biological damage and we can look into the likelihood of anyone being injured by it.

Here's a 1984 study saying the dose from Krypton (vented years after the accident) was insignificant compared to the initial accident [1]. Where are you getting your info?

Regarding no one being warned... again, where are you getting this info? It looks like they were warned by the Washington Post [2].

"Downwind" assumes dispersal by turbulent airflow over a large area.

But krypton gas is 3x as dense as air. Xenon is 5x. They don't mix eagerly with air, but run downhill more like a (fluffy) liquid. Riding above the water, they run freely over low obstacles to water flow, and spread out far beyond the water's edge. These gases would have run down the Susquehanna River and spread out in the bottom lands along it.

The paper cited in [1] is extremely guarded in its estimates of exposure to Kr radioisotopes, particularly concerning the more active ones like Kr87, 88, and 79. They note that helicopter sampling would produce unreliable measures, and the first measurements of any kind did not occur until 2 days after the incident, when the most active would have largely decayed, and (anyway) run downstream.

The peer-reviewed "A reevaluation of cancer incidence near ..." by Wing et al. ( https://ehp.niehs.nih.gov/doi/pdf/10.1289/ehp9710552 ) concludes that increased incidence of cancer around the plant is not consistent with published estimates of releases.

Evacuation was not suggested until two days after the event, and few did, as there were numerous assurances that it was safely contained.

Disingenuous disavowals of harm no not increase credibility.

Your link gives me a 404, but it looks like you're referring to https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1469835/ right? This article does not mention krypton at all, by name. Do you have anything that talks about this statement you made, in particular?

There's also a pretty good critique of the paper you cited here: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1469856/pdf/env...
