Coffinite Uranium Rock 0.7 Oz. 20,000 Cpm, and similar items

NOTE that I will leave home on Friday November 29th, for a 17 day trip to test radiation levels of recent lava at an active Hawaiian volcano. If you buy any uranium rocks after that date, it is unlikely that the package will arrive prior to Christmas Day. COFFINITE NATURAL URANIUM ROCK Radiation level: 20,000 CPM; Found at the URAVAN COLO. uranium field May 2020 COFFINITE is a fairly 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 rocks to be found, on or 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 20,000. 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
