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.
