Random Medium-Activity Uranium Ore Sample — 25K–29K CPM
These are individual natural radioactive mineral samples measuring approximately 25,000 to 29,000 CPM on a Ludlum Model 3 with 44-9 pancake probe. This medium-activity range makes them excellent starter specimens for beginner collectors, element collectors, or anyone looking for an inexpensive natural radiation check source for Geiger counter demonstrations.
Each order includes one randomly selected rock sample. These pieces are commonly cut or broken from larger uranium-bearing specimens and may contain visible 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
• Dimensions: Varies by individual sample
• Locality: Mixed / varies by sample
• Condition: Natural, unprocessed, no stabilization or enhancement
RADIATION INFORMATION
• Measured Activity: ~25,000–29,000 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 medium-activity stock.
• 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: Moderate. These are not low-background curiosities; they are clearly measurable radioactive mineral samples while still being approachable for newer collectors.
• 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 anyone wanting an affordable natural uranium-bearing specimen.
