CARNOTITE 22.5 oz. $55.00 plus $12.80 shipping Natural Uranium Rock CARNOTITE Weight: 22.5 oz (big, heavy!) Radioactivity: 59,200. CPM (counts-per-minute) This rock, and many others, were collected during July 2025, when I was accompanied in the field by a rockhounding enthusiast from west Texas. CARNOTITE is a special variation of uranium mineral, because it has been known during the past century that some carnotite rocks also contain a recoverable portion of RADIUM, which can be up to three million times more radioactive than uranium itself. Radium glows in darkness, and from the 1920s until the 1970s, a radium-based liquid paint, UNDARK, was applied to numerals on wristwatch to make them glow-in-the-dark. Women employees at the American Radium Co. painted the watch dials, and were encouraged by their employer to lick the end of the paintbrush to keep the tip tightly pointed; they ingested small but toxic amounts of the radium substance, harming their health. From this, their lawyer won for them the first-ever class-action lawsuit for their personal injury. These events are shown in a recent Hollwood movie, RADIUM GIRLS. This rock has some easily seen patterns of yellow-orange coloration, which is the natural color of uranium oxide, U3-O8 . This colored substance on uranium rocks is widely known as: YELLOWCAKE. The 300 small uranium mines at Uravan Colorado on Hwy 141, are known to have rocks that mix Carnotite with radium. NO radium has been found with carnotite at Jurassic Canyon, near Grants NM. SHIPPING will be via the USPS Post Office's "ground advantage," which includes $100.00 of delivery insurance in case of loss during mailing. However, NOTE that no insurance payment will be made if postal records show that the parcel was left at the addressee's doorstep, which suggests that the package had been stolen by "porch pirates" after being delivered. If you will temporarily be away from home when delivery is expected, then ask a friend or nearby relative to collect the package on your behalf.
