So how much were we getting back when I was a kid and the US, Russia, and China were setting off atmospheric nuke blasts?
I remember a time in the 1970’s when my mother refused to serve us fresh milk (just the horrible Carnation instant stuff) because the ChiComs had set off an atmospheric test which was producing radioactive isotopes in milk.
Dunno.
I am not an expert, but I know how to read the meter.
