United Nuclear Geiger Counter Test Card

Ideal for testing a wide variety of radiation detection equipment, our inexpensive Geiger Counter Test Card is handy, easy to use, and safe. 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 geiger counter (or its probe) on the rear of the card and you will instantly know if your geiger counter is operating. The Geiger Counter Test Card provides low level Alpha, Beta & Gamma radiation (approximately 1000 to 1500 CPM) which is easily picked up by radiation detectors. Works with all standard geiger counters. The Test Card will not work with common surplus Survey Meters, which are only designed to detect extremely high levels of radiation. Please note: The color on the back of the test cards may vary. The Test Card will still experience the same effects/results regardless of the material color. it is the united nuclear owned by "Bob Lazar."
