These are individual natural uranium-bearing rock samples measuring approximately 10,000 to 15,000 CPM. This activity range makes them excellent entry-level radioactive mineral specimens for beginner collectors, element collectors, Geiger counter demonstrations, or anyone looking for an inexpensive natural radiation source.
Each order includes one randomly selected rock sample in the size option chosen. These specimens are commonly cut or broken from larger uranium-bearing rocks and may contain carnotite, uraninite, or associated uranium mineralization, depending on the individual piece received. Photos are provided as a general representation only. Exact size, shape, color, mineral coverage, and appearance will vary.
SPECIFICATIONS
• Weight: Varies by individual sample and selected size
• Dimensions: Varies by individual sample and selected size
• Locality: Mixed / varies by sample
• Condition: Natural, unprocessed, no stabilization or enhancement
SIZE OPTIONS
• Extra Small: compact sample selected for activity in a smaller piece
• Regular: standard random uranium ore sample
• Large: larger physical specimen for display or handling comparison
RADIATION INFORMATION
• Measured Activity: ~10,000–15,000 CPM
• Instrument: Ludlum Model 3 with 44-9 pancake probe
• UV Response: Not tested / varies by sample
• Shipping: Ships legally under UN 2910 – Excepted Radioactive Material
⚠️ Radiation Notice:
This specimen emits measurable ionizing radiation. Avoid prolonged handling and display appropriately.
COLLECTOR NOTES
• These are random uranium-bearing rock samples selected from the 10K–15K CPM activity range.
• Possible uranium minerals: carnotite, uraninite, or related uranium mineralization depending on the individual sample.
• Non-uranium minerals: host rock varies, but may include sandstone, quartz, iron oxides, vanadium minerals, or other associated matrix minerals.
• Activity relative to size: Mild to moderate. These are approachable beginner specimens with clear Geiger counter response.
• Best use case examples: beginner radioactive mineral specimen, Geiger counter demonstration, classroom comparison sample, inexpensive natural radiation source, or element collection starter piece.
• Best for: beginner collectors, element collectors, educators, Geiger counter owners, and customers wanting an affordable natural uranium-bearing specimen.
