Note - The Test Sample will work with the common yellow CDV-700 Civil Defense units, which are true Geiger Counters. However, it will not work with the old Survey Meters, such as the CDV-715 or CDV-717. These are not Geiger Counters, they are very high range Survey Meters and as such, can only be tested with very high (and lethal) levels of radiation. Please note: The color on the back of the test cards can change depending on the material being used. Do not worry you will still experience the same effects/results regardless of the material color. The Geiger Counter Test Sample provides low-level Gamma & Beta radiation which is easily picked up by common radiation detectors. Works with all standard Geiger counters.
