I saw Dark Waters this week. And in my opinion, it is must-see for all of us who run around in streams, mud, and natural areas which may have been exposed to perfluorinated compounds, or PFOSs.

Used since the 1920's for ScotchGard and Teflon, PFOS compounds have already spread around the world's environment. And consequently all of us have absorbed a permanent amount of the compound, since for years chemical companies were allowed to dump the compound down the drain, or bury it in old landfills:

...the introduction of perfluorinated compounds (PFASs) in the mid-twentieth century unleashed a wave of persistent and toxic chemicals into the environment, contaminating everything from food and drinking water to the dust around us. Also known as “forever chemicals,” these substances continue to persist in the environment and in our bodies even after a partial phase-out of their production in the United States, often resistant to even the most advanced water treatment technologies...

....PFASs pose serious risks to human health: high cholesterol, thyroid disease and weight gain, decreased fertility, adverse impacts on the liver and on the immune system. PFASs may cause cancer; exposed humans were observed to have correlating increases in testicular and kidney cancer....

I regard Dark Waters as timely a must-see movie as China Syndrome was back in 1980 when Three Mile Island was blowing up just as the movie was premiering!

Similar health concerns are now being uncovered related to the use of fluoro ski waxes:

If you do orienteering for many years, you got exposed, one way or the other, to something deadly, toxic or radioactive. It is unavoidable.

I recall long ago I ran on a map around Argonne National Laboratory.
I was glowing in the dark for weeks after that.

You should embrace a persona yurets! Perhaps the Alabamian Uranium Ukrainian?

Even bananas are radioactive...
There are anecdotal stories of uranium mine site workers who want a day off work, stuffing their faces with bananas so that they won't pass the daily Geiger-counter test.

Off topic but if I did it right, the amount of K40 in a human is roughly the same as that in 300 bananas ie a whole bunch
