It consists of a card with a small radioactive source attached to the back. The card is enclosed in 4 mil plastic making it waterproof and durable. The card does not need to be removed from the plastic enclosure to use.
Simply place your radiation detection instrument (or its probe) on the rear of the card and you will instantly know if your Geiger counter is operating.
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.
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.
