[Milsurplus] Radium and the USPS

[David Ross]

Ray & the gang -

Not all TBYs have radium paint -  some have lettering & legends done as 
bare aluminum.

I think that, when an Ra226 atom emits an alpha particle, the atom also 
emits other items which are also detectable.  Maybe electrons, maybe 
high-energy photons (gamma rays).

Way more than an aircraft instrument at 2 to 5 mR/ph and way beyond the 0.5 mR/ph the R-390 "warning" tagged meters produce. I know that just about everything blocks Alpha but what would happen if you ship a TBY thru USPS or UPS? Anyone shipped one lately?
