I had a conspiracy theorist tell me one time this is why they removed all the lead paint. It never quite made sense that kids were actually eating lead chips.
I know lead is bad for you, maybe a coincidence.
There is a pattern called 'Pica' where kids gnaw on stuff, windows, ledges etc https://en.wikipedia.org/wiki/Pica_(disorder)
Apart from what the sibling poster said about lead (II acetate) having a sweet taste, little kids will put literally anything in their mouths. You ain't lived till you had to get dog shit out of a baby's mouth.

You know that lead tastes sweet, right?
Even old lead paint didn't have a lot of lead in it. A thin layer of lead paint with <1% lead does nearly nothing for WiFi signals.
We use lead for shielding ionizing radiation like gamma rays, but even that uses a lot more lead than you'd find in paint.
Not all "radiation" is the same thing.
