Cov hluav taws xob tawg yog tag nrho hluav taws xob khiav tawm hauv qhov chaw sib dhos tshwj tsis yog rau cov nqaj muaj txiaj ntsig. Nws yog feem ntau tswj los ntawm kev tsim ntawm lub raj vaj tse thiab cov collimator filtering kom zoo. Txoj kev hluav taws xob yog sum tawg hluav taws xob thiab tawg hluav taws xob.
Tseem yuav paub yog, X-ray tshuab puas tuaj yeem tawg hluav taws xob?
Txhua qhov xau los ntawm lub collimator yog tib yam li cov dej ntws los ntawm txhua qhov chaw nyob ib puag ncig x - ray cev vaj. Cov hlau lead tiv thaiv nyob rau hauv vaj tse thiab cov collimator hniav yog tuab txaus kom nres feem ntau ntawm cov hluav taws xob , thiab qhov tsawg heev uas tau los ntawm yog cov xau hluav taws xob.
Tsis tas li ntawd, thawj X ray beam yog dab tsi? Thaum muaj kev cuam tshuam, x - ray hluav taws xob tawm hauv lub raj raws li lub npe hu ua thawj beam . Thaum lub thawj beam dhau los ntawm lub cev, qee qhov hluav taws xob yog absorbed hauv cov txheej txheem hu ua attenuation.
Tsis tas li ntawd, dab tsi yog qhov txwv ntawm kev xa hluav taws xob los ntawm kev kuaj X ray raj?
tus tawg hluav taws xob ntsuas ntawm qhov deb ntawm 1m ntawm lub x - ray qhov chaw tsis pub tshaj 1 mGy/hr (100mR/hr) thaum lub cev yog ua haujlwm ntawm nws qhov siab tshaj plaws ntawm qhov siab tshaj plaws tam sim no uas tso cai rau kev ua haujlwm tas mus li.
Secondary radiation ntawm X rays yog dab tsi?
Secondary hluav taws xob hais txog hluav taws xob keeb kwm los ntawm kev nqus ntawm yav dhau los hluav taws xob hauv qhov teeb meem. Nws tuaj yeem yog nyob rau hauv daim ntawv ntawm electromagnetic nthwv dej lossis ntawm cov khoom txav.

Dab tsi yog qhov txawv ntawm kev txuag hluav taws xob thiab lub hauv paus ntsiab lus ntawm kev txuag hluav taws xob?
Lub caloric txoj kev xav tau khaws cia tias cov cua sov tsis tuaj yeem tsim los yog rhuav tshem, qhov kev txuag ntawm lub zog ua rau lub hauv paus ntsiab lus tsis sib xws uas cov cua sov thiab cov tshuab ua haujlwm sib hloov tau
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
Dab tsi yog tib yam hauv txhua qhov hluav taws xob hluav taws xob?
Electromagnetic hluav taws xob yog ib hom hluav taws xob uas feem ntau hu ua lub teeb. Feem ntau hais lus, peb hais tias lub teeb mus rau hauv nthwv dej, thiab tag nrho cov hluav taws xob hluav taws xob hluav taws xob mus rau tib qhov ceev uas yog li 3.0 * 108 meters ib ob los ntawm lub tshuab nqus tsev
Dab tsi yog qhov zoo ntawm kev siv lub tshuab hluav taws xob hloov hluav taws xob hauv atomic absorption?
Qhia qhov zoo thiab qhov tsis zoo ntawm lub cub tawg piv nrog kev siv cov nplaim taws hauv atomic absorption spectroscopy. Cov txiaj ntsig tseem ceeb yog ntau dua rhiab heev (concentration thiab tshwj xeeb tshaj yog loj). Lub ntsiab tsis zoo yog cov cuab yeej cuab tam ntau dua thiab cov nqi ntsuas
