This sliced uranium ore comes directly from miners working classic claims on the Colorado Plateau. Each piece was precision-cut with a diamond saw to expose the internal structure and quality of the ore. You’ll receive a representative slice—not the exact piece photographed, but of similar size, thickness, and radioactivity.
These slices are ideal for collectors seeking authentic material with strong detector response, visible ore bands, and historical provenance. Each one offers a clear cross-section of uranium mineralization.
Weight: About 6 oz
Dimensions: approx. 3 × 3 × 0.5 inches
Locality: Green River uranium district, Utah, USA
Condition: Sliced natural rock
Measured Activity: ~90,000 CPM (average)
Instrument: Pancake Geiger probe (device-dependent)
UV Response: None observed
Shipping: Ships legally under UN 2910 – Excepted Radioactive Material
⚠️ Radiation Notice:
This specimen emits measurable ionizing radiation. Avoid prolonged handling and display appropriately.
Geology: Classic Colorado Plateau sandstone-hosted uranium
Visible uranium minerals: Yellow secondary uranium mineralization (carnotite/related species)
Associated non-uranium minerals: Sandstone matrix, iron oxides, clays
Activity level: Strong relative to size
Best use cases:
Educational and teaching specimen
CPM comparison reference
Detector and probe testing
Authentic radioactive display piece
Best for:
Uranium & element collectors
Radioactive mineral collections
Schools, labs, and instrumentation enthusiasts
