Kev kuaj xyuas cov kab mob yog qhov tseem ceeb ntawm kev siv X-ray tshuaj ntsuam xyuas hauv cov khoom noj thiab tshuaj, thiab nws yog ib qho tseem ceeb kom ntseeg tau tias tag nrho cov kab mob raug tshem tawm tag nrho tsis hais txog daim ntawv thov thiab hom ntim khoom kom muaj kev nyab xeeb ntawm zaub mov.
Cov tshuab xoo hluav taws xob niaj hnub no muaj kev tshwj xeeb, ua tau zoo thiab siab heev, thiab tau siv dav hauv kev lag luam rau kev tshuaj xyuas, suav nrog kev kuaj mob, tshuaj xyuas khoom noj thiab tshuaj, kev tsim kho (cov qauv, mining thiab engineering), thiab kev ruaj ntseg. Hauv thaj chaw ruaj ntseg, lawv tau siv los "pom" hauv lub nra lossis pob khoom. Cov chaw tsim khoom noj khoom haus thiab cov chaw muag tshuaj kuj tso siab rau X-ray tshuab txhawm rau txheeb xyuas thiab tshem tawm cov khoom tsis huv los ntawm cov kab ntau lawm los tiv thaiv cov neeg siv khoom, txo qhov kev pheej hmoo ntawm cov khoom rov qab thiab tswj lawv cov npe.
Tab sis ua li cas X-ray tshuab kuaj cov kab mob? Kab lus no piav qhia seb X-rays yog dab tsi thiab X-ray kev tshuaj xyuas cov tshuab ua haujlwm li cas.
1. X-ray yog dab tsi?
X-rays yog ib qho ntawm ntau cov hluav taws xob tshwm sim thiab yog ib qho kev pom tsis pom ntawm hluav taws xob hluav taws xob, xws li xov tooj cua tsis. Txhua hom hluav taws xob hluav taws xob hluav taws xob yog ib qho txuas ntxiv hauv electromagnetic spectrum, teem raws li zaus thiab wavelength. Nws pib nrog xov tooj cua tsis (ntev wavelength) thiab xaus nrog gamma rays (luv wavelength). Qhov luv wavelength ntawm X-rays tso cai rau lawv nkag mus rau cov ntaub ntawv uas opaque rau pom lub teeb, tab sis lawv tsis tas yuav nkag mus rau tag nrho cov ntaub ntawv. Kev xa tawm ntawm cov khoom yog kwv yees hais txog nws qhov ntom ntom - qhov ntom ntom nws yog, tsawg dua X-rays nws kis. Cov kab mob zais zais, suav nrog iav, cov pob txha calcified thiab hlau, tshwm sim vim lawv nqus X-rays ntau dua li cov khoom nyob ib puag ncig.
2. X-ray kev soj ntsuam cov ntsiab lus tseem ceeb
Nyob rau hauv luv luv, X-ray system siv lub tshuab hluav taws xob X-ray los ua ib qho hluav taws xob xoo hluav taws xob qis rau ntawm lub sensor lossis lub tshuab ntes. Cov khoom lossis pob khoom dhau los ntawm X-ray beam thiab ncav cuag lub ntsuas. Tus nqi ntawm X-ray zog absorbed los ntawm cov khoom muaj feem xyuam rau lub thickness, ceev thiab atomic naj npawb ntawm cov khoom. Thaum cov khoom dhau los ntawm X-ray beam, tsuas yog lub zog ntxiv mus txog qhov ntsuas. Kev ntsuas qhov sib txawv ntawm qhov nqus ntawm cov khoom thiab cov khoom tsis huv yog lub hauv paus ntawm kev kuaj xyuas lub cev txawv teb chaws hauv kev kuaj X-ray.
