    Just don’t eat it or breathe it. Alpha emitters are generally a non-issue outside the body where shielding (air) and distance are available. Put alpha emitters in lung tissue or in bone near the marrow and alphas can do some serious long-term damage. Nothing to be paranoid about; just treat radioactive material with appropriate caution as you would with high voltage, live steam, or any other hazard. Know the risks and don’t be cavalier about them.

    Thoughts on breaking out the GM tube on a thin bit of coax or other appropriate cable, maybe via a tiny BNC connector? One could enclose the signal processing & HV (tube bias) bits for safety & durability and let the tube wander into harms' way.
    I need one of these and some calibration sources; it’ll go great with my Civil Defense survey meter, dosimeter, & reader/charger. Now I’m tempted to break out my copy of Knoll’s “Radiation Detection & Measurement” and see what kind of a fun tutorial I could come up with.

    This is what a well-written warrant is for. The phrase “Not without a court order or warrant; you’ll need to talk to our lawyer” when politely delivered to law enforcement might have a snowball’s chance in hell of actually evoking a reasonable response, especially if you’re not the droids, er, suspect they’re looking for. Helping law enforcement write a warrant that is appropriately narrow helps protect customer privacy while giving the cops the information they’re looking for. Everyone but the criminals win.

    I think I saw some anime with that thing in it and it gave me nightmares for weeks…

    Seriously, parts need to be kept segregated lest you wind up with a tiny brood of memristors or klystrons. Those things are harder to get rid of than a litter of kittens. And they’re not RoHS-compliant (the parts, not the kittens) so you can’t just tie them in a sack with some rocks and toss them in a pond. Come to think of it, you can’t do that with kittens anymore either, though you’d need a bigger box to keep them in. You’d probably have to poke holes in the lid. I guess this is why I’m not allowed to have pets.
    (apologies to humor-impaired kitten lovers everywhere…)

No public wish lists :(
