Just found a very very radioactive clock (>4000CPM on my Bull Elec dual tube counter) which seems to be radium based.
It makes the counter beep on its highest setting!

Where did you find it?
I need to find time to build a counter around the Russian GM tube I picked up a while back. I'd love to find some more radioactive odds & ends. I don't even know why it's so fascinating.
