At 1 foot from the dial, the count drops to 500CPM - a 10-fold decrease but that still seems quite large to me. BTW, it looks like this was painted all over the dial on this clock. I have another variation of this clock that only has it on the hands. CPM is the same though. I also checked a radio/alarm clock from about 1960. It too is radioactive, but an order of magnitude less - or maybe the plastic covering that clock is stopping more of the particle.
Yes, none of them glow in the dark any more. Is there something I could get that would light up under the bombardment? Like some glow-in-the-dark paint? It would be fun to mess with this a little. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
