Uraninite Specimen – 110,000 CPM – With Radioactive Secondaries – 10g
This is a compact yet intensely radioactive specimen of uraninite with visible secondary uranium minerals. Measuring approximately 1 × 1 × 0.5 inches and weighing 10 grams, this piece reads ~110,000 CPM on a Ludlum Model 3 with a 44-9 pancake probe. Secondary mineralization—likely including carnotite or other oxidized uranium species—is visible across the surface and contributes to the exceptional activity level. Ideal for experienced collectors, instrument calibration, or as a “hot” centerpiece in a compact form.
Weight:
10 grams (0.35 oz)
Dimensions:
1 × 1 × 0.5 inches
(25.4 × 25.4 × 12.7 mm)
Activity:
~110,000 CPM on Ludlum Model 3 with 44-9 probe
