    I can't imagine anyone who stops in here hasn't checked out the Ht board but just in case!

    This isn't in freedom and self reliance for a reason :help: My boy (and future geologist) has inherited a rock and mineral sample collection from my Uncle who was a geologist who passed away several years ago. Unfortunately my Aunt is not a geologist and to be frank there are lots (hundreds of pounds of samples) that could contain radioactive minerals. I don't want to assume they're all safe I know he has at least one sample of uraninite, and my boy will find school uses for the detector I'm looking at. Trouble is I don't know a decent detector from Hoover vacuum cleaner. Anyone know if this will do what we'll need? Fortuantely I do have access to family who should know this stuff too, but the mroe info I have the better choice I'll make!

    Poratabliity is a non issue the boy has a better laptop than most of us homesteaders will ever see.

    Gcounters have to be calibrated regularly, or they are unreliable. I have a link somewhere to a place that refurbishes and sells CD counters, and recalibrate them.

    it isnt cheap, as an ebay special would be. just cuz it ticks dont mean its working right.

    i was in the market for one "just in case" to have one on the shelf.... the diff between a surplus/used one @ around 10 bucks and a fixed calibrated one was...

    alot... i'll dig out that link for you.

    Thanks, when you check out the ebay guys site he has a method to calibrate the machine and explains why the old surplus jobbies are not what I need. I'll check out your link though thanks!
