TYUYAMUNITE NATURAL URANIUM ROCK Radiation level: 39,000 CPM; Found at Jurassic Canyon NM uranium field June 2015 $23.00 plus $9.50 shipping (If two or more rocks are purchased at the same time, then the shipping cost of ONE purchase will cover the combined shipment, and I will then REFUND the overpayment on total shipping, that was paid by the buyer. 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. Radiation levels above 40,000. CPM are considered high levels, with regard to comparison with other natural radioactive rocks. This rock, with its 39,000. CPM response, is upper-mid level. NOTE that applications in industrial, medical, or military uses have 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 timesmore 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. Learn more about Gamma Ray Bursts at YouTube! There are now about 80 teaching videos on GRBs at YouTube; this is one of the most amazing topics in all of astronomy. My P3 geiger probe has a large 3" pancake sensor made at Ukraine in the late 1980s for the USSR Soviet military; it is tuned to respond mainly to gamma rays; if aimed upward at the sky, it could detect distant GRB signals from other galaxies, such as the one that hit Earth in October 2022. $23.00 plus $9.50 shipping Stephen Buggie, Ph.D. Professor Emeritus of Psychology Univ. of New Mexico, Gallup Gallup NM 87301-6979
