Thats what I was thinking.
In ohio not far from a nuke plant where my father was working men in white outfits and geiger counters came over to take some readings. They assured him there was nothing to worry about it was all routine...................
Never believe them when they say "We're from the government and we're here to help you."
Especially if they're wearing white suits and carrying Geiger counters.
If they were wearing white suit, they just did not want to get dirty. If they had show up in yellow suits , then I would worry.
