geiger counter radiation detection circuit

[AF5U]

I plan to build one that will be powered from a car 12 volt system. This project would be a good addition to amateur radio club member needing a method to track radiation in an emergency situation.

Where to buy the GM tube? What is the price range? Thx

Ha, it looks almost like the one I just bread boarded. 

Cheers,

Will this detect alpha particles?

[LUCENT31M]

thanks john..this is incredible for me.

nice demo

should have used a cheap $10 400v geiger tube instead of the expensive alpha window type.

try and put the whole circut inside a cdv-715 case...it would be kick ass!
