Compact and easy to use, it’s designed for professionals and enthusiasts who demand confidence in their radiation detection tools without the hazards of high-level radioactive materials. ## Description Full description not available ## Features - United Nuclear 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. ## Product Details - **Material:** Plastic - **Brand:** United Nuclear - **Item dimensions L x W x H:** 2 x 4 x 0.2 inches - **Color:** Color May Vary - **Shape:** Rectangular ## Images ![United Nuclear Geiger Counter Test Card - Image 1](https://m.media-amazon.com/images/I/51DaZxY0CTL.jpg) ![United Nuclear Geiger Counter Test Card - Image 2](https://m.media-amazon.com/images/I/610wxXCEsKL.jpg) ![United Nuclear Geiger Counter Test Card - Image 3](https://m.media-amazon.com/images/I/51BysfrvGnL.jpg) ![United Nuclear Geiger Counter Test Card - Image 4](https://m.media-amazon.com/images/I/510arLR+90L.jpg) ![United Nuclear Geiger Counter Test Card - Image 5](https://m.media-amazon.com/images/I/61MyTx3WbtL.jpg) ## Questions & Answers **Q: is it ok to use in my pasta dish?** A: No. NEVER mix radioactive materials with food. **Q: Does this sample provide alpha, beta and gamma sources?** A: This sample contains small quantities of Uranium compounds which emit Beta and Gamma radiation. **Q: Do I need a lead pig, what should the card be stored in ?** A: The test card does not require any special storage. We recommend that you keep it in a metal or plastic container for long term storage, however this is not strictly necessary. **Q: What material is inside?** A: None of the packaging says what it is. It just says "...a small amount of naturally occurring radioactive material. The radiation emitted from this sample is small, and not considered a hazard." ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works on NR-750 monitor *by A***S on June 14, 2024* Showed 400CPM on a Pudibel NR-750 radiation monitor. Background was 10 CPM +/-5I left the radiation test card in the outer plastic jacket with the paper spec sheet inside on one side of the source card. So that is two protective plastic jackets. With the least amount of obstructions it measured 400CPM. the other side was around 290 to 300. The meter was placed on the source about the centerRadiation drops off at about a foot above the center.For storage, I put it in a plastic tackle box in the middle using the two storage shelves to hold it in the center. The meter measured 10CPM directly over the card so I think this is a safe storage method. I wrote Radiation Test Source on the box top and side. ### ⭐⭐⭐⭐⭐ Above and Beyond *by A***R on June 1, 2024* Between the two samples from the Geiger Counter Radiation Test Card and The Uranium Ore my handheld Muller Tube GQ GMC-800 geiger counter averages were: CPM=3,093 - μSv/h=20.11 - mR/h=2.01 - CPS=65The readouts would be even higher if I took the samples out of the plastic but I actually sealed them with an extra 4 mil airtight Plymor bag before testing.I'm impressed by these samples. Great way to check your background radiation gear and examine radioactive minerals and anything else you want to test.The alpha radiation is rated at CPM 19,000 if you are using an alpha capable probe for the readout of the Uranium Ore.Happily nuclear,Starry ### ⭐⭐⭐⭐⭐ Got about 50 uSv/hr with the yellow goop on an IMI Onyx-NX10 *by J***R on April 3, 2022* It works. Well, that was fun. With background less than 2 uSv/hr, this is at least 25 times background. I'll be sure to put it somewhere safe, not as far away as the smoke detectors though, those were pretty nasty. I've stopped using my Phaltzgraff plates since they were pretty hot. Too bad, I liked them.Two feet away, and the radiation is completely undetectable. The Geiger counter reads 0.075 uSv/Hr, which is better than normal for background radiation. This is really odd and makes me wonder if the little radioactive goop is sucking the local radiation in, to spurt it out more powerfully. That could be a great marketing ploy: protect your home from radiation, install this goop on the window, or something. It would probably be debunked, like when they all used to drink radioactive water in the old days, like around 1900 maybe, and had pitchers in which were holders for their thorium or uranium, or worst of all, Radium. They would bathe in nuclear springs. They would play on swings, not wear seatbelts, smoke cigarettes, etc. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sk/products/293348119-united-nuclear-geiger-counter-test-card](https://www.desertcart.sk/products/293348119-united-nuclear-geiger-counter-test-card) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-06-07*
