These are individual natural uranium-bearing rock samples measuring approximately 20,000 to 24,000 CPM on a Ludlum Model 3 with 44-9 pancake probe. This medium-activity range makes them excellent radioactive mineral specimens for beginner to intermediate collectors, element collectors, Geiger counter demonstrations, classroom comparison samples, or anyone looking for an affordable natural uranium-bearing specimen.
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.
THREE SIZES AVAILABLE
• Extra Small: compact sample selected to fit the extra-small specimen box; best for collectors who want a smaller, activity-dense piece
• Small: standard random uranium ore sample; best value and most economical option in this CPM range
• Regular: larger physical specimen; best for display, handling comparison, or customers who prefer a more substantial rock
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
RADIATION INFORMATION
• Measured Activity: ~20,000–24,000 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 20K–24K 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 material.
• Activity relative to size: Moderate to strong. These specimens provide a clear Geiger counter response while remaining approachable for newer collectors.
• Best use case examples: radioactive mineral specimen, Geiger counter demonstration, classroom comparison sample, natural uranium ore example, or element collection piece.
• Best for: beginner to intermediate collectors, element collectors, educators, Geiger counter owners, and customers wanting a stronger natural uranium-bearing specimen without moving into individually listed premium material.
