25g Autunite Fragments, Fluorescent Uranium Mica Shipped in a Lead Pig

Common Name: autunite

Locality: Shandong Provence

Mineral: calcium uranyl phosphate, also called calco-uranite

Autunite contains 48.27% virgin uranium. This specimen will glow bright green in the presence of UV light due to the presence of phosphorus.

This listing is for one Lead Pig containing at least 25 grams of calco-uranite (autunite) mica fragments. The size of the lead pig is 62mm in maximum diameter by 83mm tall.

You will receive the specimens shown in the last picture. The excess weight is intended to make up for any matrix that may be found attached to the pieces. The last photograph was taken without any extra UV light, so that’s why it looks different than the others.


Shipped with USPS Select Ground only in a plastic bag in a lead container to protect from crushing and bring the parcel surface activity well below the 0.5mR/hr shipping limit.
(the unshielded specimen itself has an activity above 70 Bq/gram)
