Dab tsi yog qhov txawv ntawm ionizing hluav taws xob thiab hluav taws xob electromagnetic?
Nyob rau hauv physics, hluav taws xob yog suav hais tias yog ib txoj kev uas muaj zog hais los yog nthwv dej propagate nyob rau hauv qhov chaw. Vim qhov txawv ntawm lub zog ntawm hluav taws xob nws tus kheej, cov tshuaj tiv thaiv mechanism ntawm nws cov kev cuam tshuam nrog cov teeb meem kuj txawv. Peb feem ntau faib hluav taws xob ua ob hom: ionizing hluav taws xob thiab tsis muaj hluav taws xob ionizing. Feem ntau, tsis yog ionizing hluav taws xob tseem hu ua electromagnetic tawg.
Ionizing hluav taws xob yog cov hluav taws xob uas ionizes teeb meem thaum lub zog diffuses sab nraud hauv daim ntawv ntawm electromagnetic nthwv dej los yog hais thiab ncaj qha los yog tsis ncaj qha cuam tshuam nrog nws.
Lub hom phiaj tseem ceeb ntawm ionizing hluav taws xob muaj xws li alpha rays, beta rays, X-rays, gamma rays, thiab neutron radiation. X-ray thiab gamma rays yog electromagnetic tsis, tab sis vim lawv lub zog siab, lawv tau nkag mus rau hauv qeb ntawm ionizing hluav taws xob.
Ionizing hluav taws xob tau muab faib ua cov hluav taws xob hluav taws xob thiab hluav taws xob.
Cov hluav taws xob ntuj yog hais txog cosmic rays los ntawm qhov chaw sab nrauv, nrog rau cov hluav taws xob hluav taws xob muaj nyob hauv huab cua, dej, av, pob zeb, zaub mov, thiab lwm yam ntuj tsim.
Cov hluav taws xob hluav taws xob tau siv dav hauv lub neej niaj hnub, xws li kev kuaj mob X-ray, tshuaj nuclear, qog hluav taws xob, kev cuam tshuam hluav taws xob, thiab lwm yam kev kuaj hluav taws xob thiab kev kho mob; Tsis muaj kev puas tsuaj xws li kev tsim hluav taws xob nuclear thiab kev sim kev lag luam hauv cov chaw tsim hluav taws xob nuclear, kev tswj xyuas qhov zoo, qhov ntom ntom, noo noo cov ntsiab lus, cov khoom siv, thiab thickness hauv cov tshuab ntsuas hluav taws xob, cov xov tooj cua ntawm cov khoom siv hluav taws xob thiab cov dej hauv dej xws li kev txiav roj, hluav taws xob ua haujlwm. , thiab lwm yam; Kev hloov hluav taws xob, hluav taws xob yug me nyuam, hluav taws xob tua kab mob, kev txuag hluav taws xob thiab lwm yam kev siv hluav taws xob hauv kev ua liaj ua teb; Tub rog nuclear riam phom, submarines, thiab lwm yam.
Electromagnetic hluav taws xob yog qhov tshwm sim uas lub zog tawm ntawm qhov chaw mus rau hauv qhov chaw nyob rau hauv daim ntawv ntawm electromagnetic tsis thiab propagates nyob rau hauv qhov chaw. Hom hluav taws xob no feem ntau yog tsim los ntawm kev txav ntawm cov nqi. Tsis zoo li ionizing hluav taws xob, hluav taws xob hluav taws xob tuaj yeem pom txhua hnub. Piv txwv li, xov tooj cua nthwv dej, microwaves, thiab infrared teeb tag nrho yog cov hluav taws xob hluav taws xob. Hauv qhov no, yog tias siv tau zoo, hluav taws xob hluav taws xob hluav taws xob ua lub luag haujlwm tseem ceeb hauv peb lub neej.
Kev tiv thaiv hluav taws xob ionizing: feem ntau los ntawm kev ua kom lub sij hawm raug luv, nce kev ncua deb ntawm qhov chaw, siv cov ntaub thaiv npog kom txo tau qhov raug, thiab tiv thaiv kev nqus thiab nqus cov khoom siv hluav taws xob. Ntau hom kev thaiv cov ntaub ntawv thiab cov txheej txheem yog siv rau cov rays sib txawv.
Kev tiv thaiv hluav taws xob hluav taws xob: Ntau yam khoom siv hauv tsev, khoom siv hauv chaw ua haujlwm, xov tooj ntawm tes, thiab lwm yam yuav tsum zam kom tsis txhob ua haujlwm ntev li ntau tau, thiab ntau yam khoom siv hauv tsev yuav tsum siv tib lub sijhawm kom ntau li ntau tau. Kev ceev faj yuav tsum tau them kom tawm tsawg kawg ib zaug ib teev. Hauv kev noj zaub mov txhua hnub, ib tus yuav tsum noj ntau cov zaub mov uas muaj vitamin A, C, thiab cov protein xws li carrots, txiv lws suav, kelp, nqaij ntshiv, thiab tsiaj lub siab los txhim kho lub cev muaj peev xwm tiv thaiv hluav taws xob hluav taws xob.
