This uranium ore comes from a deposit near Joshua Tree National Park in California. The ore also contains other radioactive isotopes that come from the decay of uranium. Most of the gamma radiation will be coming from the tiny bit of radium in the ore. Most of the radiation can be blocked with either glass or plastic. The radiation is the most intense right at the surface of the ore sample usually in a ceratin area on the sample.


Care should be taken while handling the ore sample. Gloves are recommended for handling the ore sample and having some kind of Geiger counter on hand is highly recommended as well. Handling of the ore sample should be done in an area that can be cleaned easily or outside. Uranium ore is really only a hazard if its ingested or inhaled. Keeping it in a display case should pose no problems. The ore will produce a small amount of radon gas over time from natural radioactive decay. The activity of the sample was measured at 1300 CPM (counts per minute) using a Radeye B20 meter. This reading is a combination of alpha, beta and gamma radiation coming from the sample at the surface. This reading can only be recreated using a meter that has a pancake probe and can detect alpha, beta and gamma radiation.
