Geiger Counter Test Card

Description: 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 owned by "Bob Lazar." Geiger Counter Test Card is ideal for testing Geiger Counters and other low-level radiation detection equipment. The back of the test card contains a small amount of naturally occurring radioactive material powerful enough to be detected by any Geiger Counter, yet safe for handling and general use. Depending on the type of probe used and the sensitivity of your Geiger Counter, the card will typically produce a reading from about 1,000 to 4,000 CPM (counts per minute). Since there are varying amounts of material in each card, the cards cannot be used for calibration and are intended to test for functionality only. If you see the analog meter or digital display with a 'CPM' , 'mR' or 'mR/h' - the Test Card will work. Instruments like Survey Meters are specifically designed to detect deadly amounts of radiation, like that from nuclear detonations or reactor melt-downs. These instruments will not respond to the Test Card. These types of radiation detectors require very high (potentially lethal) radiation sources to test them - nothing that the general public is permitted to have. These units will read in R (roentgens) or R/h (roentgens per hour). Only the Survey Meter manufacturers, or specially licensed testing facilities are able to test these instruments. Please note the active area on the back of the card may vary in color.
