Radiation yog lub zog. Nws tuaj yeem los ntawm tsis ruaj tsis khov atoms tsis ruaj tsis khov atoms Cov ntsiab lus uas tawm ionizing hluav taws xob hu ua radionuclides. Thaum nws lwj, radionuclide hloov mus rau hauv ib qho atom sib txawv - cov khoom lwj. Cov atoms hloov mus rau cov khoom lwj tshiab kom txog thaum lawv mus txog lub xeev ruaj khov thiab tsis muaj xov tooj cua ntxiv lawm. https://www.epa.gov › radiation › radioactive-decay

uas dhau los ntawm hluav taws xob tawg, lossis nws tuaj yeem tsim los ntawm cov tshuab. Radiation mus los ntawm nws qhov chaw nyob rau hauv daim ntawv ntawm lub zog tsis muaj zog los yog energized hais. Muaj ntau hom hluav taws xob sib txawv thiab lawv muaj cov khoom sib txawv thiab cov teebmeem.
Cov hluav taws xob tsim tawm li cas?
Feem ntau ntawm cov hluav taws xob tom qab tshwm sim naturally 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 uas tshwm sim hauv ib txwm muaj.
hluav taws xob ua los ntawm dab tsi?
Radiation yog lub zog muab tawm los ntawm qhov teeb meem hauv daim duab ntawm cov kab hluav taws xob lossis cov kab hluav taws xob nrawm. Txhua yam teeb meem yog tsim los ntawm atoms. Atoms yog tsim los ntawm ntau qhov chaw; lub nucleus muaj cov kab me me hu ua protons thiab neutrons, thiab lub atom lub plhaub sab nrauv muaj lwm cov khoom hu ua electrons.
Dab tsi yog hluav taws xob tsim tawm?
Radiation-tsim cov khoom siv tsim X-rays los ntawm kev ua kom cov hluav taws xob nrawm los ntawm qhov hluav taws xob muaj peev xwm thiab nres lawv hauv lub hom phiaj. • Ntau yam khoom siv uas siv hluav taws xob siab thiab qhov chaw ntawm cov hluav taws xob tsim hluav taws xob X-ray raws li qhov tsis xav tau los ntawm cov khoom lag luam. Cov no yog hu ua xwm txheej X-rays.
Yuav ua li cas yog nuclear hluav taws xob tsim?
Zoo muab tawm los ntawm cov teeb meem hauv daim ntawv me me nrawm nrawm (alpha hais, beta hais, thiab neutrons) lossis pulsating electromagnetic rays lossis nthwv dej (gamma rays) emitted los ntawm lub nuclei ntawm tsis ruaj tsis khov radioactive atoms.

Hauv cov khoom siv hluav taws xob tsim hluav taws xob?
Nyob hauv cov khoom siv hluav taws xob tsim hluav taws xob, xws li hlau, hluav taws xob rhaub, boiler, toaster thiab lwm yam, ib qho hlau xws li Nichrome Nichrome Nichrome (tseem hu ua NiCr, nickel-chromium lossis chromium-nickel) yog ib tsev neeg ntawm cov alloys ntawm npib tsib xee, chromium, thiab feem ntau hlau (thiab tejzaum nws muaj lwm yam) feem ntau siv raws li cov hlau tsis kam, cov khoom cua sov hauv cov khoom xws li toasters thiab qhov chaw tso cua sov, hauv qee qhov
Lub tshuab hluav taws xob tsim hluav taws xob nyob qhov twg?
Generac G-FORCE® thiab OHVI cov cav yog tsim thiab tsim los ntawm Generac Power Systems Inc. ntawm peb cov chaw hauv Wisconsin. Cov khoom lag luam Generac nyob qhov twg? Generac yog lub hauv paus hauv Waukesha, Wisconsin, thiab muaj chaw tsim khoom hauv Berlin, Oshkosh, Jefferson, Eagle, thiab Whitewater;
Puas yog lub tshuab hluav taws xob nyob ruaj khov tsim hluav taws xob nthwv dej?
Tsis yog ib qho hluav taws xob nyob ruaj ruaj lossis cov hlau nplaum nyob ruaj ruaj yuav tsim thiab EM yoj. Lawv yuav tsum txav los tsim nthwv dej. Puas electrons tsim hluav taws xob nthwv dej? Electromagnetic nthwv dej yog tsim los ntawm kev txav electrons.
Puas hluav taws xob hluav taws xob puas tsim hluav taws xob?
Coal feem ntau siv roj los tsim hluav taws xobhauv Tebchaws Meskas. Hauv cov chaw tsim hluav taws xob hluav taws xob hluav taws xob, cov hluav taws xob bituminous, subbituminous thee, lossis lignite raug hlawv. Cov cua kub uas tsim los ntawm kev sib xyaw ntawm cov thee yog siv los hloov cov dej mus rau hauv qhov chaw siab zog, uas tsav lub turbine, uas tsim hluav taws xob.
Lub tshuab hluav taws xob hluav taws xob tsim hluav taws xob li cas?
Piav seb lub twj hluav taws xob hluav taws xob tsim hluav taws xob hla lub membrane li cas. Los ntawm pum electrons hla lub membrane, sab uas cov electrons raug tshem tawm muaj qhov zoo dua, thaum sab tau txais cov hluav taws xob ntau muaj qhov tsis zoo.
