CD V-700 Geiger Counter

The CD V-700 (Wikipedia) is a geiger counter designed to detect low levels of beta and gamma radiation.  The device was designed by US Civil Defense and manufactured by numerous companies.  I managed to score one on eBay from someone who had purchased them from a state surplus sale of some kind for just $55.  This particular geiger counter was built by Electro Neutronics, but hasn’t been calibrated since 1998.  So far, I have only been able to pick up some background radiation present in my room, but I have some uranium glass marbles at home that I’d like to test.
