Ib daim ntawv ntawm hluav taws xob yog lub zog ntshiab nrog tsis hnyav. Daim ntawv no ntawm hluav taws xob - lub npe hu ua electromagnetic hluav taws xob - zoo li vibrating lossis pulsating rays lossis "yoj" ntawm hluav taws xob thiab sib nqus zog . Daim ntawv no tsis tshua paub txog hluav taws xob suav nrog alpha hais, beta hais, thiab neutrons, raws li tau piav qhia hauv qab no.
Raws li txoj cai, beta rays ua los ntawm lub zog ntshiab?
Alpha thiab beta rays yog tsim ntawm discrete subatomic cov khoom . Qhov no yog ib feem ntawm vim li cas cov no rays yog yooj yim dua deflected los ntawm tsawg ntom teeb meem. Lawv yog lub zog ntshiab thiab hluav taws xob yog li tsuas yog qhov ntom ntom ntawm cov teeb meem tuaj yeem deflect nws. Gamma rays tuaj yeem pom muaj nyob txhua qhov chaw hauv lub qab ntuj khwb.
Kuj Paub, cov ntaub ntawv dab tsi tuaj yeem thaiv hluav taws xob? Tsis yog txhuas cov ntaub thaiv npog yog tsim nrog additives thiab binders tov nrog attenuating hnyav hlau uas poob rau hauv tib qeb ntawm cov ntaub ntawv raws li txhuas uas kuj nqus los yog thaiv hluav taws xob . Cov no hlau tej zaum yuav suav nrog tin (Sn), antimony (Sb), tungsten (W) bismuth (Bi) lossis lwm yam khoom.
Kuj paub, dab tsi yog daim ntawv txaus ntshai tshaj plaws ntawm hluav taws xob?
Gamma rays
Dab tsi yog hluav taws xob?
Hauv physics, hluav taws xob yog lub emission los yog kis ntawm lub zog nyob rau hauv daim ntawv ntawm nthwv dej los yog hais los ntawm qhov chaw los yog los ntawm ib tug khoom nruab nrab. Qhov no suav nrog: electromagnetic hluav taws xob , xws li xov tooj cua tsis, microwaves, infrared, pom lub teeb, ultraviolet, x-rays, thiab gamma hluav taws xob (γ)

Tus kws tshaj lij hluav taws xob puas tuaj yeem ua tus kws kho hluav taws xob?
Koj tuaj yeem tau txais koj pib nrog tsawg asatwo-xyoo Associate's degree thiab ntawv pov thawj los ntawm AmericanRegistry of Radiologic Technologists. Ntau yam rad techspursueradiology tshwj xeeb, xws li mammography. Lwm tus txiav txim siab ntxiv lawv txoj haujlwm los ntawm kev rov qab mus rau tsev kawm ntawv los ua tus kws kho mob
Dab tsi yog cov yam ntxwv ua siab hloov hluav taws xob hloov hluav taws xob LET muaj thaum piv nrog LET hluav taws xob tsawg?
Dab tsi yog cov yam ntxwv ua kom muaj hluav taws xob hloov hluav taws xob siab (LET) hluav taws xob muaj thaum piv nrog cov hluav taws xob qis-LET? Cov huab hwm coj ntau ntxiv, txo qhov nkag mus. (Vim lawv cov nqi hluav taws xob thiab cov khoom loj heev, lawv ua rau ntau ionizations hauv cov ntaub so ntswg, sai sai poob lub zog
Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms?
Tus nqi zoo attracts tus nqi tsis zoo thiab ua rau lwm tus nqi zoo. Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms? Cov nqi hluav taws xob yog cov cuab yeej ntawm tag nrho cov atoms
Lub co2 hluav taws tua hluav taws puas ua haujlwm ntawm hluav taws kub oxidizer?
Lub tshuab tua hluav taws xob carbon dioxide tsis yog qhov kev xaiv zoo rau kev tua hluav taws oxidizer vim nws ua haujlwm ntawm lub hauv paus ntsiab lus ntawm kev tsis suav nrog cov pa oxygen, thiab cov pa oxygen atmospheric tsis xav tau rau hluav taws kub oxidizer.
