CARNOTITE NATURAL URANIUM ROCK $22.00 + $9.50 s/h Radiation level: 23,000 CPM; Found at Jurassic Canyon NM uranium fields August 2018 Weight: 6.5 ounces $22.00 plus $9.50 shipping via Ground Advantage USPS CARNOTITE is a common uranium mineral. Typically, it has scattered colors of yellow and black on its rock surface. Jurassic Canyon NM is the USA's richest location for uranium natural rocks to be found, on or near the ground surface. The world price of uranium has risen significantly during early 2024; I expect that mines that have been closed for 25 years, since 1989, will reopen at the canyon before the end of 2024 ! Radiation levels above 40,000. CPM are considered high levels, with regard to comparison with other natural radioactive rocks. This rock, with 23,000. CPM is middle level response. (NOTE that applications in industrial, medical, or military uses have far higher radiation levels than those found in natural uranium rocks.) CARNOTITE sometimes has crusty flakes, imbedded in sandstone. This is one of the very common uranium minerals found at uranium mine fields. ALPHA RADIATION is the radiation type that is most easily blocked by barriers, even by clothing, paper, or the skin. Alpha radiation is the radiation type that is most commonly emitted by natural uranium. ( By contrast, Gamma ray radiation, is the "Macho" type of radiation. Gamma rays penetrate all barriers, even metals such as lead. Gamma rays make space travel difficult, because cosmic rays in outer space are mainly gamma radiation. Cosmic radiation at the ISS space station is 240 times more intense than natural surface radiation on Earth; At the surface of red planet Mars, the radiation is 730 times more intense than Earth's surface radiation. The Gamma Ray Burst of October 2022, a tightly focused narrow beam, traveled 2.4 billion light years to Earth; it was the most intense energy event since the early "Big Bang." That GRB interrupted low-frequency AM- radio on Earth for four days. $22.00 plus $9.50 shipping Stephen Buggie, Ph.D. Professor Emeritus Univ. of New Mexico, Gallup Gallup NM 87301-6979
