Muaj ntau qhov chaw ntawm cov xov tooj cua isotopes. Qee cov xov tooj cua isotopes tam sim no yog cov hluav taws xob hauv av. Radioactive isotopes ntawm radium, thorium, thiab uranium, piv txwv li, muaj nyob rau hauv pob zeb thiab avUranium thiab thorium kuj tshwm sim hauv cov kab hauv dej.
Yuav ua li cas cov isotopes radioactive tsim?
Isotopes tuaj yeem tsim ib txwm muaj (naturally) dhau ntawm cov hluav taws xob tawg ntawm lub nucleus(piv txwv li, emission ntawm lub zog hauv daim ntawv ntawm alpha hais, beta hais, neutrons, thiab photons) los yog artificially los ntawm bombarding ib tug ruaj khov nucleus nrog them hais los ntawm accelerators los yog neutrons nyob rau hauv lub nuclear reactor.
cov khoom siv hluav taws xob los ntawm qhov twg?
Cov khoom siv hluav taws xob tshwm sim ib txwm muaj los ntawm cov tswv cuab ntawm uranium thiab thorium decay chains, suav nrog radium thiab radon. Cov khib nyiab uas muaj qib siab ntawm cov no feem ntau tsim los ntawm tib neeg cov dej num, xws li mining thiab milling ntawm uranium ore, thee burning, thiab dej kho.
xov tooj cua isotopes tsim nyob qhov twg?
Radioisotopes yog isotopes ntawm cov tshuaj lom neeg. Lawv muaj lub zog ntau dhau, uas lawv tso tawm nyob rau hauv daim ntawv ntawm hluav taws xob. Lawv tuaj yeem tshwm sim los yog raug tsim tawm, feem ntau hauv kev tshawb fawb reactors thiab accelerators.
Dab tsi yog qhov laj thawj tseem ceeb ntawm cov xov tooj cua hauv isotope?
Dab tsi ua rau atoms ua cov xov tooj cua? Atoms pom nyob rau hauv cov xwm yog qhov ruaj khov los yog tsis ruaj khov. Ib qho atom ruaj khov yog tias cov rog ntawm cov khoom uas pleev lub nucleus yog sib npaug. Lub atom tsis ruaj khov (xov tooj cua) yog tias cov rog no tsis sib npaug; Yog hais tias lub nucleus muaj qhov ntau dhau ntawm lub zog sab hauv.
