Like all radioactive samples sold by United Nuclear, the radiation levels measured are
combined Beta and Gamma radiation.
We never include Alpha radiation measurements as that produces a deceivingly high reading.

A certificate of accurate radiation measurement is included with all samples.

Typical Low Level Uranium Ore samples

Low Level Uranium Ore samples - ideal for beginning collectors or as an inexpensive radiation source.
Our Low Level Ore samples are generally a combination of the following Uranium minerals (in various amounts): Carnotite (yellow), Uraninite (black), and Gummite (brown).
They can be sealed in a zip-loc bag for most uses so any chips or small particles will not get lost with rough handling (the Beta & Gamma radiation they emit easily penetrates the zip-loc bag).
Although they are safe to handle with your hands, it is prudent to wash your hands after handling the samples to prevent ingesting radioactive chips or fine particles that may fall of the rocks.
All samples are guaranteed to measure between 2,000 CPM and 9,000 CPM.
Samples typically measure anywhere from about 2" across to 3.5" across. 
As with all our Uranium ore samples, a certificate stating your sample's precise radiation
 measurement & associated information is included with your purchase.
