Nyob rau hauv lub tshav pob ntawm kev kho mob thiab hluav taws xob kev nyab xeeb, qhov tseem ceeb ntawm X-ray shielding tsis tau overstated. Raws li cov neeg ua haujlwm kho mob thiab cov neeg mob paub ntau ntxiv txog qhov muaj feem cuam tshuam nrog kev raug hluav taws xob, qhov kev thov rau cov ntaub thaiv kev ruaj ntseg tau nce ntxiv. Ntawm ntau qhov kev xaiv muaj, cov iav txhuas tau dhau los ua qhov kev xaiv nrov rau X-ray shielding vim nws cov khoom tshwj xeeb thiab kev ua tau zoo.
X-ray Shielding yog dab tsi?
X-ray shielding yog hais txog kev siv cov khoom tsim tshwj xeeb los tiv thaiv cov tib neeg los ntawm kev phom sij ntawm ionizing hluav taws xob tawm thaum kuaj X-ray. Qhov no yog qhov tseem ceeb tshwj xeeb hauv ib puag ncig xws li tsev kho mob, chaw kho hniav thiab cov chaw tshawb fawb uas siv tshuab X-ray nquag siv. Lub hom phiaj tseem ceeb ntawm X-ray shielding yog kom txo cov hluav taws xob raug rau cov neeg mob thiab cov neeg ua haujlwm kho mob, kom muaj kev nyab xeeb thiab ua raws li ib puag ncig.
Vim li cas Lead Glass?
Lead iavyog ib hom iav tshwj xeeb uas muaj cov hlau lead oxide, uas ua rau nws muaj peev xwm nqus tau thiab txo qis X-ray hluav taws xob. Cov iav ua tau zoo ua cov khoom thaiv tiv thaiv yog ntaus nqi rau nws qhov siab ntom ntom thiab atomic tus lej xov tooj, uas ua rau muaj hluav taws xob zoo nkauj thiab gamma rays. Qhov no ua rau cov iav txhuas yog qhov kev xaiv zoo tshaj plaws rau cov ntawv thov uas qhov kev pom kev pom kuj tseem muaj kev txhawj xeeb, xws li X-ray saib qhov rais thiab kev tiv thaiv kev tiv thaiv.
Ib qho txiaj ntsig tseem ceeb ntawm cov iav txhuas yog nws cov pob tshab. Tsis zoo li cov khoom siv lead ua uas cuam tshuam qhov pom, cov iav iav tso cai rau pom tseeb ntawm X-ray txheej txheem thaum tseem muab kev tiv thaiv tsim nyog. Qhov no yog qhov tseem ceeb tshwj xeeb hauv cov chaw kho mob, qhov twg cov neeg ua haujlwm kho mob yuav tsum tau saib xyuas cov neeg mob thaum lub sij hawm ntsuas cov txheej txheem yam tsis muaj kev cuam tshuam rau lawv txoj kev nyab xeeb.
Kev siv cov iav txhuas hauv X-ray shielding
Lead iav muaj ntau yam kev siv hauv kev kho mob. Qee qhov kev siv tseem ceeb tshaj plaws suav nrog:
- X-ray saib windows: Hauv cov chaw ua haujlwm hluav taws xob, cov iav txhuas feem ntau yog siv los ua qhov rais saib kom cov neeg ua haujlwm kho mob saib cov duab X-ray yam tsis muaj kev cuam tshuam los ntawm hluav taws xob. Cov qhov rais no yog tsim los muab kev pom siab tshaj plaws yam tsis muaj kev nyab xeeb.
- Kev tiv thaiv kab mob: Cov iav siv lead ua tuaj yeem siv los tiv thaiv kev tiv thaiv lossis tshuaj ntsuam kom cais cov neeg mob los ntawm cov neeg ua haujlwm kho mob thaum kuaj X-ray. Cov teeb meem no yog qhov tseem ceeb los txo qis hluav taws xob cuam tshuam rau cov neeg ua haujlwm kho mob thaum ua kom cov neeg mob tau txais kev saib xyuas tsim nyog.
- Cov chaw kho hniav: Hauv cov chaw kho hniav, cov iav txhuas feem ntau yog siv hauv cov tshuab xoo hluav taws xob thiab saib cov chaw los tiv thaiv cov neeg mob thiab cov kws kho hniav los ntawm hluav taws xob. Lub pob tshab ntawm cov iav txhuas ua rau kev sib txuas lus thiab kev saib xyuas thaum cov txheej txheem yooj yim.
- Cov chaw tshawb fawb: Hauv cov chaw soj nstuam uas tshawb fawb siv cov khoom siv X-ray, cov iav thaiv iav siv lead ua los tiv thaiv cov kws tshawb fawb los ntawm hluav taws xob raug thaum tso cai rau lawv ua haujlwm zoo.
Hauv cov ntsiab lus
Raws li thaj chaw ntawm kev kho mob txuas ntxiv mus, qhov tseem ceeb ntawm X-ray shielding tseem ceeb heev. Lead iav yog ntau yam thiab muaj txiaj ntsig zoo rau kev tiv thaiv tib neeg los ntawm kev raug hluav taws xob thaum tswj kev pom thaum ua haujlwm. Nws cov khoom tshwj xeeb ua rau nws yog ib qho tseem ceeb rau ntau yam kev siv, los ntawm cov tsev kho mob mus rau cov chaw kho hniav thiab cov chaw tshawb fawb.
Hauv kev xaus, kev nkag siab lub luag haujlwm ntawm cov iav txhuas hauv X-ray shielding yog qhov tseem ceeb rau cov kws kho mob thiab cov neeg mob. Los ntawm kev saib xyuas kev nyab xeeb thiab siv cov ntaub ntawv tiv thaiv zoo, peb tuaj yeem xyuas kom peb ua kom tau txais txiaj ntsig zoo tshaj plaws ntawm X-ray thev naus laus zis thaum txo cov kev pheej hmoo tsawg. Raws li peb mus tom ntej, kev nce qib ntxiv hauv kev tiv thaiv thev naus laus zis yuav ua lub luag haujlwm tseem ceeb hauv kev txhim kho hluav taws xob kev nyab xeeb hauv kev kho mob duab.
