Qhov laj thawj tseem ceeb uas uraninite yog mined yog muab roj rau cov chaw tsim hluav taws xob nuclear. Uranium tuaj yeem pom hauv yuav luag txhua pob zeb. Uranium muaj nyob rau hauv tsawg kawg ib kab nyob rau hauv pob zeb xws li sedimentary limestones rau granites mus rau volcanic tephras.
YPuas yog uraninite yog cov ntxhia tsis tshua muaj?
Lub cev muaj zog ntawm Uraninite
Zoo-tsim crystals ntawm uraninite yog qhov tsawg heev. Thaum pom lawv feem ntau yog cubes, octahedrons thiab hloov cov ntawv. Uraninite feem ntau tshwm sim raws li botryoidal lossis granular crust ntawm lwm cov ntaub ntawv.
uraninite feem ntau pom nyob qhov twg?
Uraninite tau txais los ntawm hydrothermal vein deposits, xws li cov nyob rau hauv Jáchymov thiab nyob rau hauv ib qho chaw nyob ib sab ntawm lub Ore Toj siab (Erzgebirge) nyob rau hauv Lub teb chaws Yelemees. Lwm cov hlab ntsha muaj nyob ntawm Great Bear Lake hauv Northwest Territories ntawm Canada thiab hauv Lake Athabasca koog tsev kawm ntawv ntawm Alberta thiab Saskatchewan.
pitchblende siv rau dab tsi?
Pitchblende thawj zaug tau muab rho tawm rau tsim cov tshuaj pleev xim siv hauv kev lag luam iav. Tus kws tshuaj German Klaproth hauv xyoo 1789 tau kuaj pom uranium los ntawm kev tshuaj xyuas pitchblende. Xyoo 1896, AH Becquerel nrhiav pom qhov tshwm sim ntawm cov xov tooj cua.
Puas yog txiv tsawb puas muaj hluav taws xob?
Qee cov poov tshuaj ib txwm coj los ntawm kev noj zaub mov, thiab qee qhov ib txwm tso tawm, txhais tau hais tias tsis muaj cov tshuaj poov tshuaj ntau ntxiv. Yog li, thaum txiv tsawb yog qhov tseebxov tooj cua, koob tshuaj radioactivity lawv xa tsis ua rau muaj kev pheej hmoo.
