Qhov hluav taws xob electromagnetic los ntawm qhov twg? Yuav ua li cas kom tsis txhob muaj hluav taws xob electromagnetic
Peb nyob hauv lub ntiaj teb uas muaj cov nthwv dej electromagnetic, uas cuam tshuam nrog lub neej txhua hnub thiab kev ua haujlwm. Los ntawm cov TV, xov tooj ntawm tes, khoos phis tawj, induction cookers, thiab microwave ncu, mus rau antennas, substations, thiab mobile kev sib txuas lus hauv paus chaw nres tsheb, cov cuab yeej siv thiab cov chaw tsim khoom tsim hluav taws xob hluav taws xob. Thaum tib neeg tau txais ntau yam yooj yim hauv lawv txoj haujlwm thiab lub neej, qhov teeb meem hluav taws xob hluav taws xob hluav taws xob uas tuaj nrog nws kuj tau nyiam ntau yam. Yog li, koj muaj kev paub ntau npaum li cas txog hluav taws xob hluav taws xob? Yuav ua li cas ib tug yuav txo tau lawv raug rau electromagnetic hluav taws xob? Tus editor yuav qhia rau koj txog kev tsom xam ntawm cov kws tshaj lij MVG.
Qhov hluav taws xob electromagnetic los ntawm qhov twg?
Cov hluav taws xob hluav taws xob los ntawm cov hluav taws xob hluav taws xob, uas tsis pom thiab tsis pom, tab sis nyob rau txhua qhov zoo li huab cua. Electromagnetic nthwv dej nyob rau hauv ib puag ncig nyob yuav muab faib ua ob pawg: ntuj electromagnetic nthwv dej thiab dag electromagnetic tsis.
Ntuj electromagnetic nthwv dej xa mus rau electromagnetic nthwv dej generated nyob rau hauv cov xwm. Nyob rau hauv qhov xwm txheej, txhua yam khoom uas muaj qhov kub thiab txias tshaj li xoom, suav nrog peb tib neeg lub cev, emits lub zog rau lub ntiaj teb sab nraud, uas yog qhov peb hu ua "kua hluav taws xob". Raws li paub zoo, lub ntiaj teb nws tus kheej yog qhov chaw sib nqus loj, thiab lub hnub ci, xob laim, thiab lwm lub ntiaj teb tuaj yeem tsim hluav taws xob hluav taws xob. Tib neeg tau hloov zuj zus hauv ib puag ncig no.
Nrog rau txoj kev loj hlob ntawm kev tshawb fawb, tib neeg tau tsim ntau qhov chaw siv hluav taws xob nthwv dej los ua haujlwm, uas emit electromagnetic tsis los yog tsim hluav taws xob thiab sib nqus teb rau hauv ib puag ncig. Piv txwv li, peb niaj hnub siv hluav taws xob tsim hluav taws xob tsawg zaus electromagnetic teb; Mloog xov tooj cua siv xov tooj cua yoj; Cov xov tooj ntawm tes thiab microwave ncu siv ntau zaus microwaves.
Qhov no yog ib qho teeb meem loj, tab sis nws tsis tuaj yeem teb ncaj qha li "kev puas tsuaj" lossis "tsis muaj mob". Tam sim no, theem hluav taws xob ntawm hluav taws xob hluav taws xob ntawm tib neeg lub cev ua raws li cov qauv ntawm cov chaw tshawb fawb tshwj xeeb, thiab International Commission on Non Ionizing Radiation Protection (ICNIRP) yog lub luag haujlwm tseem ceeb rau kev tsim cov qauv no. Cov qauv no tau muab tso rau hauv txoj cai lij choj hauv tebchaws los qhia meej txog cov kab hluav taws xob ntawm cov hluav taws xob hluav taws xob.
Yog li ntawd, tsuas yog hluav taws xob hluav taws xob hluav taws xob ntau tshaj li cov qauv txwv tuaj yeem ua rau muaj kuab paug electromagnetic, uas muaj qee yam cuam tshuam rau ib puag ncig thiab tib neeg kev noj qab haus huv. Nws yog ib qho tsim nyog hais tias ntau tus neeg ntseeg tias cov kav hlau txais xov yog qhov loj tshaj plaws ntawm hluav taws xob hluav taws xob. Qhov tseeb, cov khoom siv uas peb siv xws li tshuab ziab plaub hau, xov tooj ntawm tes, routers, thiab microwave ncu kuj tsim hluav taws xob, thiab cov hluav taws xob hluav taws xob sib txawv raws li kev ua haujlwm sib txawv.
