    beta/alpha radiation which is the worst kind if ingested.  Do you know if it is sensitive enough to detect the gamma emissions from a smoke detector if you put the detector right next to one?

      to the presence of contamination, but will miss the more dangerous internal hazard stuff. My G-M has a slide window on the probe, so I can get a gamma read and then open the shield to get a beta-gamma read. Do the simple math and I've got a decent beta count. Alpha needs a different type of detector, but if you know it's coming from a meltdown or bomb, it's best to simply assume the alpha is present. Take proper precautions.

      And unlike the gaseous emissions and vaporized fuel, alpha-emitting isotopes will hang closer to the ground because they're relatively heavy particulates. Nasty, nasty stuff.

      Here's some good material for those who think they have reason for concern -
