Petrified Wood with Uranium infusion

After scanning tens of thousands of petrified wood specimens, one with some radioactive qualities was finally uncovered and it was a really nice specimen.

Billed as "from the world's oldest tree", it also had an impressive price. Since the store owner had no idea that any of his stock was radioactive, indeed said that the entire store "had been scanned by a professional", he sold the specimen for a much reduced price to "get that thing out of here".
 
The radioactive inclusion is white against the dark background of the Petrified Wood, and does glow under UV.
 

Attached is a spectrum scan that clearly indicated strong lower daughters of the Uranium U-238 series.

 
Have fun
