Uranium Ore 5,000 to 10k CPM

Random Uranium Ore Sample — 5,000–10,000 CPM | Beginner Tier

These are single, unaltered uranium ore specimens with activity ranging from 5,000 to 10,000 CPM, measured using a Ludlum Model 3 with a 44-9 pancake probe. This is an ideal entry-level activity range, making these samples well suited for first-time collectors, classrooms, or anyone needing a modest, reliable radiation source for instrument testing.

Most pieces are natural fragments broken or cut from larger uranium-bearing rocks and commonly contain secondary uranium minerals such as carnotite, with occasional uraninite-bearing zones depending on the individual specimen. Each piece is randomly selected from stock, and photos are provided as a general representation of the material—not the exact specimen you will receive.
