These are bulk lots of natural uranium-bearing run-of-mine ore, sorted by measured activity range. Each lot contains mixed pieces of natural ore and is available in 1 lb, 2 lb, or 5 lb quantities. This material is ideal for collectors, educators, Geiger counter demonstrations, comparison sets, and customers who want more than a single display specimen.
This is run-of-mine ore, meaning pieces will vary naturally in size, shape, color, mineral coverage, and appearance. Some pieces may show visible yellow carnotite or uranium-vanadium mineralization, while others may be darker, plainer, or more matrix-heavy. These lots are selected primarily by CPM range, not by individual display quality.
THREE ACTIVITY LEVELS AVAILABLE
• Under 10K CPM: lower-activity bulk ore with measurable response
• 10K–19K CPM: moderate activity bulk ore, good for demonstrations and starter collections
• 20K–29K CPM: stronger bulk ore with a more noticeable Geiger counter response
THREE WEIGHT OPTIONS AVAILABLE
• 1 lb lot: good starter bulk sample or classroom comparison lot
• 2 lb lot: better value for collectors wanting multiple pieces
• 5 lb lot: best value for bulk ore, sorting, display, or educational use
SPECIFICATIONS
• Weight: available in 1 lb, 2 lb, or 5 lb lots (454 g, 907 g, or 2.27 kg)
• Dimensions: mixed sizes; varies by individual pieces in the lot
• Locality: Mixed / varies by lot
• Condition: Natural, unprocessed, no stabilization or enhancement
RADIATION INFORMATION
• Measured Activity: selectable activity level: <10K, 10K–19K, or 20K–29K CPM
• Instrument: Ludlum Model 3 with 44-9 pancake probe
• UV Response: Not tested / varies by lot
• Shipping: Ships legally under UN 2910 – Excepted Radioactive Material
⚠️ Radiation Notice:
This material emits measurable ionizing radiation. Avoid prolonged handling and display or store appropriately. Keep away from food, drink, children, and pets, and wash hands after handling.
COLLECTOR NOTES
• These are bulk lots of natural uranium-bearing run-of-mine ore selected by CPM range.
• Possible uranium minerals: carnotite, uraninite, tyuyamunite, or related uranium mineralization depending on the lot.
• Non-uranium minerals: host rock varies, but may include sandstone, quartz, iron oxides, vanadium minerals, and other associated matrix material.
• Activity relative to size: varies by selected CPM range and individual pieces within the lot.
• Best use case examples: Geiger counter demonstration, educational comparison set, element collection material, sorting project, bulk display, or natural uranium ore study lot.
• Best for: collectors who want multiple pieces, educators, Geiger counter owners, element collectors, and buyers who prefer bulk natural ore over a single display specimen.
