Autunite contains 48.27% uranium. These specimens glow bright green in the presence of UV light due to the presence of phosphorus. When a sealed specimen is placed within 1/4 inch of the Geiger tube, a count of 1000CPM can be expected. The size of each vial is 40mm tall by 15.8mm in maximum diameter. Each vial is sealed closed using epoxy for safety purposes. Attempting to open the vial is not recommended.
