Thorium (tshuaj cim Th) yog naturally tshwm sim radioactive ib txwm tshwm sim radioactive Feem ntau ntawm cov hluav taws xob tom qab tshwm sim los ntawm cov zaub movthiab ib feem me me los ntawm cov khoom tsim los ntawm tib neeg. Ib txwm tshwm sim cov pob zeb hauv av, av, thiab dej tsim hluav taws xob tom qab. Tib neeg lub cev txawm muaj qee yam ntawm cov khoom siv hluav taws xob zoo li no. https://www.epa.gov › radiation › radiation-sources-and-doses

metal pom nyob rau ntawm kab hauv av, pob zeb, dej, nroj tsuag thiab tsiaj txhu. Muaj tej yam ntuj tso thiab tib neeg tsim cov ntaub ntawv ntawm thorium, tag nrho cov uas yog radioactive. … Feem ntau, ib txwm tshwm sim thorium muaj xws li Th-232, Th-230 lossis Th-228.
Puas yog thorium-232 ruaj khov lossis xov tooj cua?
Thorium yog ib yam khoom uas tshwm sim nyob rau hauv lub ntiaj teb crust. Qhov tsuas yog ib txwm tshwm sim isotope ntawm thorium yog 232Th thiab nws yog tsis ruaj tsis khov thiab xov tooj cua.
Puas yog thorium 238 radioactive?
Thaum 238U is cov xov tooj cua tsawg kawg, nws cov khoom lwj, thorium-234 thiab protactinium-234, yog beta particle emitters nrog ib nrab -nyob li ntawm 20 hnub thiab ib feeb raws li.
Yuav hluav taws xob ntau npaum li cas thorium tso tawm?
Thorium-232 (232 Th) yog tam sim no nyob rau hauv cov nyiaj tseem ceeb hauv lub ntiaj teb daim tawv nqaij thiab yog ib qho alpha-emitting radionuclide, uas lwj mus rau radium-228(228Ra), uas yog beta emitter nrog ib nrab-lub neej ntawm txog rau xyoo; nws emits tsis muaj gamma hluav taws xob tseem ceeb.
hom hluav taws xob twg ua rau thorium 230 tawm?
Thorium- 230 feem ntau yog tam sim no nrog nws cov khoom lwj radium- 226, thiab yog li ntawd nws yog ib qho kev pheej hmoo ntawm kev noj qab haus huv los ntawm gamma hluav taws xob los ntawm cov khoom siv hluav taws xob-226 lwj, lub ntsws raug los ntawm radon -222 roj thiab nws cov khoom lwj, thiab nqus tau thiab nqus tau.
