General Uranium Ore Info
Our Uranium ore is from a variety of sites throughout the USA, mined by our own prospectors. All radioactive ore is sold by radiation level, not ore type or physical size. This does not mean that you will get a sample that measures very high and is the size of a dime. All our samples are of typical 'useful size' which is in the 2" to 4" range, with most samples being about 3" across. The exception to this is our Uranium Ore Vial which contains small chips of various ores, as well as our Cloud Chamber Sources (when available) which are also intentionally small to operate in the limited space of a Cloud Chamber instrument. Uranium Ore samples may contain primary and secondary Uranium ores including: Carnotite (bright yellow), Uraninite (black crystal), Pitchblende (jet black), Uranophane (canary yellow), Gummite (rust brown), Tyuyamunite (pale green), Schroeckingerite (greenish-yellow) Ores.

How Ore is Measured
The radiation measurements stated on all of our radioactive items is guaranteed to be accurate. It is measured with a calibrated,Stabilized Assay Meter, not just a simple Geiger Counter. We measure the total Beta and Gamma radiation emissions from each sample in CPM (Counts Per Minute). The number stated under each sample is the combined Beta and Gamma emissions, taken from the area on the sample that produces the highest reading. We DO NOT measure the Alpha radiation emissions or use a "Pancake" type probe,as that produces falsely high readings. We guarantee that all samples we sell measure exactly what is stated.

Ore Uses & Applications
Lower level ores are ideal for testing Geiger Counters or other radiation detection equipment. Higher level ores are intended for laboratory experimentation or for radiological training purposes - for example where the hidden ore sample has to be located with instrumentation. Our Cloud Chamber samples are of a higher radiation level and intentionally small. This is necessary due to the limited area available in Cloud Chambers and the need to produce a large amount, and various types of visible radiation tracks at a high rate. For mineral collectors, all Uranium Ore is useful and the different varieties are rare & fascinating.

Special Note: We are currently down to the last of our Uranium ore samples and only have 'A' level samples available at this time. Our Uranium mine is still inaccessible due to snow so it will be closer to the end of April before we can get our prospectors into our mine and digging for this year's supply.
