1. Trams thiab them pawg yog ob qho tib si "electromagnetic hluav taws xob"
Thaum twg cov hluav taws xob tau hais, txhua tus yuav xav txog lub xov tooj ntawm tes, khoos phis tawj, microwave ncu, thiab lwm yam, thiab sib npaug nrog X-rays hauv tsev kho mob cov yeeb yaj kiab thiab CT scans, ntseeg tias lawv yog cov xov tooj cua thiab yuav muaj kev cuam tshuam tsis zoo rau kev noj qab haus huv. cov neeg siv. Qhov nrov ntawm kev mus ncig hluav taws xob niaj hnub no tau ua rau muaj kev txhawj xeeb ntawm qee tus tswv tsheb: "Txhua zaus kuv tsav tsheb lossis mus rau qhov chaw them nyiaj, kuv ib txwm ntshai ntawm hluav taws xob."
Qhov tseeb, muaj kev nkag siab yuam kev loj hauv qhov no. Yog vim li cas rau kev nkag siab tsis zoo yog tias txhua tus tsis paub qhov txawv ntawm "ionizing radiation" thiab "electromagnetic radiation". Cov hluav taws xob nuclear txhua leej txhua tus hais txog yog hais txog "ionizing hluav taws xob", uas yuav ua rau mob qog noj ntshav lossis ua rau cov qauv DNA puas. Cov khoom siv hauv tsev, khoom siv sib txuas lus, lub tshuab hluav taws xob, thiab lwm yam yog "electromagnetic radiation". Nws tuaj yeem hais tias txhua yam khoom raug them muaj "electromagnetic radiation". Yog li, cov hluav taws xob tsim los ntawm lub tsheb hluav taws xob thiab cov pawg them nyiaj yog "electromagnetic radiation" es tsis yog "ionizing hluav taws xob."
2. Hauv qab cov qauv ceeb toom thiab tuaj yeem siv nrog kev ntseeg siab
Tau kawg, qhov no tsis txhais hais tias "electromagnetic hluav taws xob" tsis muaj teeb meem. Thaum lub zog ntawm "electromagnetic hluav taws xob" ntau tshaj li ib tug qauv, los yog txawm mus txog "electromagnetic radiation pollution", nws kuj yuav ua rau muaj kev cuam tshuam tsis zoo rau tib neeg noj qab haus huv.
Tam sim no siv lub teb chaws tus qauv sib nqus hluav taws xob hluav taws xob kev nyab xeeb tus qauv txwv yog teem rau ntawm 100μT, thiab hluav taws xob hluav taws xob hluav taws xob hluav taws xob kev nyab xeeb yog 5000V / m. Raws li kev ntsuam xyuas los ntawm cov kws tshaj lij, cov hluav taws xob sib nqus nyob rau hauv pem hauv ntej kab ntawm lub zog tshiab tsheb feem ntau yog 0.8-1.0μT, thiab kab rov qab yog 0.3-0.5μT. Cov hluav taws xob hluav taws xob hluav taws xob hauv txhua qhov ntawm lub tsheb yog tsawg dua 5V / m, uas ua tau raws li qhov yuav tsum tau ua ntawm lub teb chaws cov qauv thiab txawm tias qis dua qee lub tsheb roj.
Thaum cov pawg them nyiaj ua haujlwm, cov hluav taws xob hluav taws xob hluav taws xob yog 4.78μT, thiab hluav taws xob hluav taws xob los ntawm rab phom taub hau thiab lub qhov (socket) them yog 5.52μT. Txawm hais tias tus nqi hluav taws xob yog me ntsis siab dua qhov nruab nrab tus nqi hauv lub tsheb, nws yog qis dua li cov qauv hluav taws xob hluav taws xob hluav taws xob ceeb toom ntawm 100μT, thiab thaum them nyiaj, khaws qhov deb ntawm ntau tshaj 20 cm ntawm pawg them, thiab cov hluav taws xob yuav yog txo 0.
Raws li qhov teeb meem tau hais hauv Is Taws Nem tias kev tsav tsheb mus ntev ntawm lub tsheb hluav taws xob yuav ua rau cov plaub hau poob, qee cov kws tshaj lij tau taw qhia tias qhov no yuav cuam tshuam nrog cov xwm txheej xws li kev tsav tsheb mus sij hawm ntev, nyob lig, thiab kev ntxhov siab, tab sis tej zaum yuav tsis muaj teeb meem. ncaj qha cuam tshuam rau kev tsav tsheb tshiab zog.
3. Tsis pom zoo: nyob hauv lub tsheb thaum them nyiaj
Txawm hais tias qhov kev pheej hmoo ntawm "kua hluav taws xob" tau raug txiav tawm, nws tseem tsis tau pom zoo kom cov neeg nyob hauv lub tsheb thaum them nyiaj. Qhov laj thawj kuj yooj yim heev. Txawm hais tias kuv lub teb chaws lub zog tshiab lub tsheb thiab cov khoom siv hluav taws xob them nyiaj yog qhov paub tab tam sim no, nws raug txwv los ntawm cov yam ntxwv roj teeb thiab tsis tuaj yeem tshem tawm tag nrho cov thermal runaway. Tsis tas li ntawd, thaum lub tsheb thauj khoom, tig lub tshuab cua txias, siv cov khoom siv hauv tsheb, thiab lwm yam yuav txuas ntxiv rau lub sijhawm tos thiab txo cov nqi them.
