Hi guys, I found this specimen in the Příbram uranium district in the Czech Republic. It appears to be coal/carbon-rich material. it's very light, but it’s extremely radioactive, which is producing strong alpha, beta, and gamma radiation. My RadEye B20-ER measured around 300,000 CPM on contact.

From what I understand, uranium-bearing coal and carbon-rich material can occur in historic uranium mining areas like Příbram, where uranium minerals became associated with organic matter over geological time. Příbram itself is one of the most famous uranium districts in Europe.

Is this type of radioactive coal considered rare to find? I’d love to hear opinions from collectors, geologists, or anyone familiar with Czech uranium mining districts.
