Uranium from Příbram (Czechia)

All images are links to high quality versions. RC-102: 1.7 kCPS [43 uSv/h]. AB+: 55 CPS, 1960 CPS Uraninite nodules in calcite (?). Unlike the Colorado plateau rocks, the veins are nice and clean (although not chemically pure) which results in a shiny surface. RC-102: 1.1 kCPS [37 uSv/h] Chunk of Uraninite growing on calcite. It has nice botryoidal formations of massive Uraninite along with some areas where the shape of the underlying calcite crystal is visible. A few of the "bubbles" are broken, showing the individual crystals that grew on the matrix. RC-102: 300 kCPS [14 uSv/h]. AB+: 25 CPS, 704 CPS Ugly Uraninite chip. Might glue this inside a cloud chamber or something: it's small, crumbly and weathered. RC-102: 3.2 kCPS [112 uSv/h] Uraninite coating "granite". RC-102: 1.3 kCPS [32 uSv/h]. AB+: 26 CPS, 1200 CPS Granite with Uraninite veins running through it. A nice crystal of calcite is visible in the third photo. Uraninite veins running through calcite (?). This might look cool…
