I had forgotten about the factory worker exposure, you are absolutely right, the people painting the dials got the stuff all over themselves (direct skin contact and ingestion from dust/fumes) and it eventually killed them. (this was before the effects of radiation were fully known and appreciated). In anycase, a friend of mine has a couple of these dials and the Geiger counter goes crazy (on its most sensitive setting that is) when you place it near one. A few feet away and its zippo. Right up close and its buzzing like hell. I'll bet you can find cheap WW2 bomber instrumentation on ebay. -Matt Matthew Dillon To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
