## Overview

The United Nuclear Geiger Counter Test Card is a compact, safe, and effective tool designed to verify the functionality of Geiger counters and low-level radiation detectors. It emits a detectable radiation level between 1,000 and 4,000 CPM using naturally occurring radioactive material, making it ideal for quick, on-the-spot testing without calibration. Compatible with most analog and digital meters, this test card is a must-have for professionals and enthusiasts seeking reliable performance verification.

## Description

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.

Review: Very nice Geiger counter, works perfectly for a guy like me who loves nuclear physics!
Review: Showed 400CPM on a Pudibel NR-750 radiation monitor. Background was 10 CPM +/-5 I 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 center Radiation 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.

## 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."

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=65 The 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
