Hi Geo,

Thank you for the reply. ?Good to see the group is still active.

Once I get the detector I'll check some of the mantels I found in my parent's house when I cleaned it out, maybe some of those are old enough to still be treated with Thorium. ?Kind of kicking myself, my Dad( He was an engineer, and built a Geiger counter for fun) had a box of radioactive items including a watch with radium dial, that I didn't keep.... Oh well, who knew I would get interested it this 10 years later. ?Now I will likely need to buy something to test the detector, I see that Amazon has Uranium ore for sale for not too much.

New to the group, just ordered a detector and was wondering what folks use for test samples? ?Old Lantern mantles? Old orange Fiestaware?

I'm new here and this seems like a small group, so I thought I would say "Hi!".

I'm hoping to meet folks that are learning more about geiger counters. I'm a science nerd and have enjoyed "learning by doing" with my geiger counter.
