'funny', when i was planning to relocate to PA i researched nuke plant locations and prevailing winds; yet, i guess this coulda been hurtin me and loved ones 75 mi away....
How could halon fire suppressant hurt you from 75 miles away?
And, did you research coal-fired power plants and prevailing winds? A typical coal plant releases more radioactive material every year, including uranium, thorium, radon, etc, than all the nuclear power plants in the world put together.
It's called "NORM" - Naturally Occurring Radioactive Material - and there's more heat energy in the uranium and thorium in coal ash than was in the coal burned to produce it.
