1950’s 1960’s Vintage Civil Defense Victoreen CD V-700 Model 6b Geiger Counter – Rated one of the best models, the Victoreen Radiological Survey Meter operates with standard batteries.
This is the CD V-700 Model 6b Geiger Counter which was used for measuring radiation, primarily in case of a massive nuclear attack on the United States or other friendly countries. The CD V-700 is a very sensitive Gamma and Beta radiation detector, so sensitive that they were considered ‘useless’ in case of a thermonuclear war. This is good for modern day experiments, disasters and ‘treasure hunting’ with a Geiger counter.
I have not tested it, and don’t know how to. As is.
