My Geiger counters (tera-p+, gmc 500+, civil defense survey meter, a couple old Polish+former USSR models) do not suggest anything beyond background in, well, the background, where I am (Southern Nevada)

But unfortunately that doesn't speak towards the possibility of micron-sized alpha emitters floating around and being inhaled as even an alpha-capable detector wouldn't pick up something like that unless you laid it right on the probe itself...and those little alpha buggers are the sort of stuff that cause the nasties if you breathe them in/eat them.

But beta/gamma/xray? Ain't seein' it.

No detectable fallout or contamination 'round here or in the veggies/fishies imported into the area 'cause I sometimes check that stuff for fun.
