TYUYAMUNITE NATURAL URANIUM ROCK Radiation level: 24,000 CPM; Found at Uravan Colorado uranium field April 2018 $28.00 plus $12.80 shipping. TYUYAMUNITE is a fairly common natural uranium mineral. It relates to another uranium mineral, CARNOTITE. Carnotite emerges as a weathered- version of Tyuyamunite, with yellow coloration where uranium is visible on the rock. Typically, it has scattered colors of yellow and black on its rock surface. Both Tyuyamunite and Carnotite rocks are found nearby in the same uranium fields, near the ground surface. Tyuyamunite is plentiful on the Colorado Plateau, near Uravan. It is also found throughout the Jurassic Canyon NM locality. It was named in 1912 after a region in Asia's Kyrgyzstan, TYUYA-MUYUN. This uranium mineral is found at many places worldwide, including Australia, New Zealand, Namibia, Central Asia, Brazil, Czech Republic, Russian Federation, Ukraine, and India. The rock does NOT glow florescently when illuminated with UV light. Radiation levels above 40,000. CPM are considered high levels, with regard to comparison with other natural radioactive rocks. This rock, with its 24,000. CPM response, is middle-level. (NOTE that applications in industrial, medical, or military uses have far higher radiation levels than those found in natural uranium rocks.) 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.) Stephen Buggie, Ph.D. Professor Emeritus of Psychology Univ. of New Mexico, Gallup Gallup NM 87301-6979
