Testing Geiger Counters 277

thesandbender writes "My girlfriend's family lives in Japan and is very interested in obtaining geiger counters for testing food and other materials. Geiger counters are now impossible to get in Japan and are on long back order from most providers in the U.S. which makes me suspicious of anything we can get our hands on. My question is, what's the best way to test/verify a geiger counter. I know I can point it at a smoke detector and it should go off but I'm not sure what I should see on the gauge. We'd even take it to any reasonable local facilities for testing (NYC area). Any input would be greatly appreciated!"

    But, for him to be karma whoring, there'd also have to be a significant number of slashdotters who don't know (which is quite the unlikely case). So, either he didn't know; or he over-estimated the number of slashdotters who don't know.

    1. the buttocks
    2. the anus
    3. a stupid person; fool

    1. The joint or bend of the arm between the forearm and the upper arm.
    2. The bony outer projection of this joint.

    Well its about ask likely as a slashdotter not knowing what a Geiger counter is.

    Vaseline is radioactive?! So you're saying I shouldn't be using it to, you know, wax my carrot?

    I can't believe so many people are doubting if slashdotters know what a Geiger Counter is when the original question begins with "My girlfriend's family". That means he's wondering if his Japanese Real Doll (Leal Doll -- don't worry, I'm Asian) is safe for sexy time.
