Raws li peb txhua tus paub, X-ray yog ib txoj kab hluav taws xob uas muaj zog ntau dua li cov kab hluav taws xob ultraviolet, uas tam sim no tau siv dav hauv kev lag luam thiab tshuaj.Vim tias nws muaj hluav taws xob ntau, nws feem ntau yuav tsum tau tiv thaiv kom zoo.Kev tiv thaiv tau muab faib ua peb hom, los ntawm kev tiv thaiv los tswj cov koob tshuaj X-ray irradiation, yog li nws tau tswj hwm ntawm qhov tsim nyog yam tsawg kawg nkaus, tsis pub tshaj cov koob tshuaj sib npaug uas tau teev tseg hauv cov qauv kev tiv thaiv hluav taws xob hauv teb chaws.Lub hauv paus ntsiab lus ntawm kev tiv thaiv lub sijhawm, kev tiv thaiv kev deb thiab kev tiv thaiv kev tiv thaiv hluav taws xob yog raws li hauv qab no:
1. Lub sijhawm tiv thaiv
Lub hauv paus ntsiab lus ntawm kev tiv thaiv lub sij hawm yog tias cov koob tshuaj ntawm irradiation ntawm cov neeg ua hauj lwm nyob rau hauv hluav taws xob teb yog proportional rau lub sij hawm, yog li ntawd nyob rau hauv cov ntaub ntawv ntawm irradiation npaum li cas, shortening lub sij hawm irradiation yuav txo tau cov koob tshuaj tau txais. tej zaum yuav muaj peev xwm ua kom muaj kev nyab xeeb ntawm tus kheej los ntawm kev tso cov tshuaj tiv thaiv hluav taws xob uas lawv tau txais qis dua qhov siab tshaj plaws uas tau tso cai (txoj kev no tsuas yog siv rau cov xwm txheej txawv txawv, thiab kev tiv thaiv kev tiv thaiv yog nyiam yog siv cov shielding tiv thaiv), yog li ua tiav lub hom phiaj ntawm kev tiv thaiv.Qhov tseeb, peb muaj cov kev paub zoo sib xws hauv lub neej, txawm tias peb mus rau hauv tsev kho mob kom teem caij rau kev kuaj X-ray, thov nkag mus rau qhov chaw kuaj mob sai li sai tau thiab ua raws li tus kws kho mob cov lus qhia kom ua tiav qhov kev sim sai sai kom txo tau qhov kev puas tsuaj. ntawm hluav taws xob rau peb lub cev.
2. Kev tiv thaiv kev deb
Kev tiv thaiv kev deb yog ib txoj hauv kev zoo ntawm kev tiv thaiv hluav taws xob sab nraud, lub hauv paus ntsiab lus ntawm kev siv cov hluav taws xob tiv thaiv kev deb yog thawj zaug siv cov hluav taws xob hluav taws xob los ua qhov chaw, thiab qhov nyiaj ntawm irradiation thiab nqus cov koob tshuaj ntawm ib qho chaw hauv cov hluav taws xob hluav taws xob yog qhov sib txawv ntawm qhov sib txawv. mus rau lub square ntawm qhov kev ncua deb ntawm qhov taw tes thiab qhov chaw, thiab peb hu txoj cai no txoj cai inverse square.Ntawd yog, qhov hluav taws xob siv hluav taws xob hloov pauv inversely proportional rau lub square ntawm qhov kev ncua deb (nyob rau hauv cov ntaub ntawv ntawm ib tug tej yam hluav taws xob siv ntawm qhov chaw, tus nqi npaum li cas los yog irradiation tus nqi yog inversely proportional rau lub square ntawm qhov deb ntawm qhov chaw).Ua kom qhov kev ncua deb ntawm qhov chaw hluav taws xob thiab tib neeg lub cev tuaj yeem txo qhov koob tshuaj los yog raug, lossis ua haujlwm sab nraum ib qho kev ncua deb kom cov koob tshuaj hluav taws xob tau txais los ntawm tib neeg qis dua qhov siab tshaj plaws, uas tuaj yeem ua kom muaj kev nyab xeeb ntawm tus kheej.Yog li kom ua tiav lub hom phiaj ntawm kev tiv thaiv.Lub ntsiab lus tseem ceeb ntawm kev tiv thaiv kev ncua deb yog ua kom qhov kev ncua deb ntawm tib neeg lub cev thiab cov hluav taws xob hluav taws xob.
Txoj cai inverse square qhia tau hais tias qhov kev siv ntawm cov rays ntawm ob lub ntsiab lus, inversely proportional rau lub square ntawm lawv nyob deb, yuav txo tau cov koob tshuaj ntawm irradiation sai li sai tau raws li qhov kev ncua deb nce.Nco ntsoov hais tias cov saum toj no kev sib raug zoo siv rau taw tes ray qhov chaw yam tsis muaj huab cua los yog khoom khoom. .Qhov tseeb, qhov hluav taws xob hluav taws xob yog ib qho ntim, tsis yog qhov chaw zoo tshaj plaws, tab sis kuj yuav tsum tau muab sau tseg tias cov hluav taws xob hluav taws xob hauv huab cua lossis cov khoom siv yuav ua rau cov hluav taws xob tawg los yog nqus, tsis tuaj yeem tsis quav ntsej qhov cuam tshuam ntawm phab ntsa. los yog lwm yam khoom nyob ze ntawm qhov chaw, yog li ntawd nyob rau hauv daim ntawv thov tiag tiag yuav tsum tau tsim kom muaj kev ncua deb kom muaj kev nyab xeeb.
3. Kev tiv thaiv kev tiv thaiv
Lub hauv paus ntsiab lus ntawm kev tiv thaiv kev tiv thaiv yog: kev siv hluav taws xob nkag mus rau ntawm cov khoom yuav tsis muaj zog, qee qhov tuab ntawm cov khoom siv tiv thaiv tuaj yeem ua rau tsis muaj zog ntawm txoj kab hluav taws xob, nruab nrab ntawm qhov hluav taws xob thiab tib neeg lub cev teeb tsa cov ntaub thaiv npog txaus (cov ntaub thaiv npog) .Nws tuaj yeem txo cov qib hluav taws xob, kom cov neeg ua haujlwm ntawm cov tshuaj txo qis hauv qab qhov siab tshaj plaws, kom ntseeg tau tias tus kheej muaj kev nyab xeeb, ua tiav lub hom phiaj ntawm kev tiv thaiv.Lub ntsiab lus tseem ceeb ntawm kev tiv thaiv kev tiv thaiv yog tso cov ntaub thaiv npog ntawm qhov chaw hluav taws xob thiab tib neeg lub cev uas tuaj yeem nqus cov rays zoo.Cov ntaub thaiv npog feem ntau rau X-rays yog cov ntawv txhuas thiab cov phab ntsa pob zeb, lossis barium cement (cement nrog barium sulfate - tseem hu ua barite hmoov) phab ntsa.
