Txoj Kev Thiab Kev Tiv Thaiv X-ray?

Nyob rau hauv xyoo tas los no, vim yog kev txhim kho ntawm cov khoom siv X-ray, tus nqi ntawm X-ray raug txo qis, thiab qhov muaj peev xwm ntawm hluav taws xob puas tau ua me thiab me. Tab sis peb tseem tsis tuaj yeem coj nws maj mam, peb tseem yuav tsum coj zooX-ray tiv thaiv, yog li yuav tiv thaiv nws li cas? Kev tiv thaiv ntawm X-rays tuaj yeem ua los ntawm peb cov lus qhia, thawj zaug yog kev tiv thaiv lub sijhawm, qhov thib ob yog kev tiv thaiv nyob deb, thiab qhov thib peb yog kev tiv thaiv kev tiv thaiv.

X-rays nkag mus rau tib neeg lub cev yuav tsim qee yam teebmeem lom. Yog hais tias tus nqi ntawm X-ray raug ntau dhau lawm, ntau tshaj qhov tso cai raug tshuaj, cov tshuaj tiv thaiv hluav taws xob tuaj yeem tshwm sim, thiab txawm tias qee qhov kev puas tsuaj hluav taws xob tuaj yeem tshwm sim. Txawm li cas los xij, yog tias tus nqi ntawm X-ray raug nyob rau hauv qhov kev tso cai, qhov cuam tshuam feem ntau yog tsawg. Tib neeg tsis tas yuav tsis kam lees qhov tsim nyog X-rays thiab CT kev kuaj mob vim yog hluav taws xob, cia ib leeg tsis kam nkag mus rau lub chaw kuaj hluav taws xob ntawm lub tsev kho mob vim qhov no.

Technical yam ntxwv: cov ntsiab cai ntawm kev tiv thaiv kev tiv thaiv thiab kev tiv thaiv nyob deb tuaj yeem txais yuav. Kev tiv thaiv kev tiv thaiv yog hais txog kev siv cov tshuaj uas muaj cov lej atomic ntau dua, feem ntau yog cov hmoov txhuas lossis cov hmoov txhuas, uas yog qhov thaiv kom nqus cov x-rays tsis tsim nyog. Kev tiv thaiv kev deb yog hais txog lub hauv paus ntsiab lus tias qhov X-ray raug inversely proportional rau square ntawm qhov kev ncua deb, thiab qhov raug txo los ntawm kev nce qhov kev ncua deb ntawm X-ray qhov chaw thiab tib neeg lub cev.

Muaj ob hom X-rays uas ncav cuag tib neeg lub cev los ntawm X-ray raj, thawj emission kab thiab lwm yam emission kab. Qhov thib ob emission kab yog generated thaum tus thawj emission kab nkag mus rau lwm yam khoom, thiab nws lub zog yog me dua li cov thawj emission kab, yog li nws muaj kev cuam tshuam ntau dua. X-ray tube shells, shading tubes thiab apertures, lim daim hlau, lead iav qab ntawm lub vijtsam, txhuas cov ntxaij vab tshaus, txhuas roj hmab aprons, lead hnab looj tes, thiab cov phab ntsa feem ntau yog siv los tiv thaiv kev tiv thaiv. Nws yog ib qho kev tiv thaiv yooj yim kom nce qhov kev ncua deb ntawm tib neeg lub cev thiab x-ray qhov chaw rau kev tiv thaiv nyob deb.

Hais txog cov neeg mob: Rau cov neeg mob uas tsis tas yuav nrog, cov neeg hauv tsev neeg tsis tas yuav mus kuaj ua ke, yog li cov hluav taws xob tawg yog qhov tsis tsim nyog. Cov neeg ua haujlwm kho mob yuav tsum tsis txhob quav ntsej txog kev tiv thaiv cov neeg mob thiab cov neeg mob vim tias lawv tsuas yog tuaj tom tsev kho mob kom kuaj xyuas; Cov neeg kawm yuav tsum muaj kev paub txog kev tiv thaiv tus kheej thiab tsis kam txais kev kho mob tsis tsim nyog. Txhawm rau kom tsis txhob raug x-ray tsis tsim nyog thiab raug ntau tshaj qhov tso cai, yuav tsum xaiv txoj kev kuaj x-ray tsim nyog thiab cov txheej txheem tshuaj xyuas yuav tsum raug tsim. Tus naj npawb ntawm qhov tshwm sim rau txhua qhov kev kuaj x-ray yuav tsum tsis txhob ntau dhau, thiab yuav tsum tsis txhob rov kuaj dua hauv lub sijhawm luv luv (qhov no yog qhov tseem ceeb tshwj xeeb rau kev kuaj mob tomography thiab angiography). Thaum projecting, yuav tsum tau them nyiaj mloog mus rau qhov tseeb ntawm qhov projecting txoj hauj lwm, scope thiab raug tej yam kev mob. Cov khoom siv tiv thaiv (cov ntaub thaiv npog, cov dab tshos txhuas, cov kaus mom hlau, cov qhov muag txhuas, cov hnab looj tes, cov ntaub thaiv hniav, thiab lwm yam) yuav tsum hnav kom npog qhov chaw uas tsis tas yuav tsum tau kuaj xyuas.

Rau cov neeg ua haujlwm hluav taws xob: kev tiv thaiv tsim nyog yuav tsum tau tsim ua raws li lub teb chaws txoj cai ntawm kev noj qab haus huv ntawm hluav taws xob, kev ua haujlwm ntawm X-ray yuav tsum ua kom raug, cov cai tswj kev noj qab haus huv yuav tsum ua tib zoo siv, thiab cov koob tshuaj tau txais los ntawm cov neeg ua haujlwm hluav taws xob yuav tsum tau ua. saib xyuas tsis tu ncua. Thaum ua haujlwm nyob rau hauv ib puag ncig xoo hluav taws xob, hnav cov hlau lead aprons, txhuas dab tshos, lub kaus mom hlau lead, lub qhov muag lead, cov hnab looj tes txhuas, cov npog ntsej muag thiab cov tiv thaiv gonad, thiab lwm yam, thiab siv lub hauv paus ntsiab lus ntawm kev tiv thaiv nyob deb los txhawb kev tiv thaiv tus kheej.

Radiation nyob ze peb
Ntxiv nrog rau X-ray hluav taws xob, muaj cov hluav taws xob zoo sib xws hauv tib neeg lub neej. Piv txwv li, khoos phis tawj, TVs, xov tooj ntawm tes, thiab microwave ncu yog ze rau tib neeg lub cev, yog li cov kev phom sij tseem ceeb heev. Tam sim no kev kho kom zoo nkauj hauv tsev feem ntau yuav qee cov vuas hauv pem teb, pob zeb kab lis kev cai, thiab lwm yam. Cov khoom siv kho kom zoo nkauj no tseem yuav tsim cov hluav taws xob ntau. Cov hluav taws xob ntawm cov vuas hauv pem teb feem ntau yog los ntawm cov hluav taws xob ntawm radon. Radon emanation yog ionizing hluav taws xob. Qhov hluav taws xob ionizing no ua rau cov molecules ntawm lub cev kom rub cov nqi zoo thiab tsis zoo ntawm cov organic molecules sib nrug, thiab tom qab ntawd tsim cov kab mob irreversible organic.

Yuav tiv thaiv cov hluav taws xob li cas? Nws yuav tsum tau hais tias ntev npaum li lub sijhawm thiab kev nyob deb tau them nyiaj rau, kev siv lub qhov cub microwave feem ntau yuav tsis ua rau tib neeg lub cev puas tsuaj. Piv txwv li, tawm mus kom deb li deb tau tom qab qhib lub qhov cub microwave, kom deb li deb kom ua tiav cov txiaj ntsig tiv thaiv, thiab koj tuaj yeem ntxiv lub npog tshwj xeeb microwave rau ntawm qhov cub microwave. Cov ntxaij vab tshaus hauv computer, mainframes, chassis, thiab txawm tias tus nas tag nrho muaj hluav taws xob. Tau kawg, cov hluav taws xob tseem ceeb tshaj plaws los ntawm qhov screen. Feem ntau, nws txaus los ua txoj haujlwm zoo hauv kev tiv thaiv hluav taws xob ntawm lub vijtsam. Koj tuaj yeem ntxiv daim thaiv hluav taws xob rau koj lub computer. Cov poj niam cev xeeb tub yuav tsum nyob deb ntawm qhov chaw hluav taws xob, txiav tawm cov hluav taws xob hauv lub sijhawm lossis hnav khaub ncaws tiv thaiv hluav taws xob rau cov poj niam cev xeeb tub.
