1. Cov tsheb ciav hlau thiab cov chaw them hluav taws xob yog ob qho tib si "hluav taws xob hluav taws xob"
Thaum twg muaj lus hais txog hluav taws xob, txhua tus neeg yuav xav txog xov tooj ntawm tes, khoos phis tawj, lub qhov cub microwave, thiab lwm yam, thiab muab piv rau cov duab X-ray hauv cov yeeb yaj kiab hauv tsev kho mob thiab CT scans, ntseeg tias lawv muaj hluav taws xob thiab yuav muaj kev cuam tshuam tsis zoo rau kev noj qab haus huv ntawm cov neeg siv. Kev nyiam mus ncig ua si hluav taws xob niaj hnub no tau ua rau qee tus tswv tsheb txhawj xeeb ntau ntxiv: "Txhua zaus kuv tsav tsheb lossis mus rau qhov chaw them hluav taws xob, kuv ib txwm ntshai hluav taws xob."
Qhov tseeb, muaj kev nkag siab yuam kev loj heev hauv qhov no. Qhov laj thawj rau kev nkag siab yuam kev yog tias txhua tus neeg tsis paub qhov txawv ntawm "ionizing radiation" thiab "electromagnetic radiation". Lub nuclear radiation uas txhua tus neeg tham txog yog hais txog "ionizing radiation", uas yuav ua rau mob qog noj ntshav lossis ua puas rau cov qauv DNA. Cov khoom siv hauv tsev, cov khoom siv sib txuas lus, cov cav hluav taws xob, thiab lwm yam yog "electromagnetic radiation". Nws tuaj yeem hais tias txhua yam khoom them muaj "electromagnetic radiation". Yog li ntawd, lub zog tsim los ntawm cov tsheb fais fab thiab cov pawg them hluav taws xob yog "electromagnetic radiation" es tsis yog "ionizing radiation."
2. Qis dua cov qauv ceeb toom thiab siv tau nrog kev ntseeg siab
Tau kawg, qhov no tsis tau txhais hais tias "hluav taws xob hluav taws xob" tsis muaj teeb meem. Thaum lub zog ntawm "hluav taws xob hluav taws xob" tshaj qhov tus qauv, lossis txawm tias ncav cuag "kev ua qias tuaj ntawm hluav taws xob hluav taws xob", nws tseem yuav tsim cov teebmeem tsis zoo thiab ua rau tib neeg muaj kev noj qab haus huv.
Tus qauv kev nyab xeeb ntawm lub teb chaws uas siv tam sim no yog teem rau 100μT, thiab tus qauv kev nyab xeeb ntawm lub teb hluav taws xob yog 5000V / m. Raws li kev sim los ntawm cov tsev kawm ntawv tshaj lij, qhov hluav taws xob ntawm lub teb hluav taws xob hauv kab pem hauv ntej ntawm cov tsheb fais fab tshiab feem ntau yog 0.8-1.0μT, thiab kab tom qab yog 0.3-0.5μT. Qhov hluav taws xob ntawm lub teb hluav taws xob hauv txhua qhov ntawm lub tsheb yog tsawg dua 5V / m, uas ua tau raws li cov kev cai ntawm lub teb chaws thiab qis dua qee lub tsheb roj.
Thaum lub pawg them ua haujlwm, lub zog hluav taws xob electromagnetic yog 4.78μT, thiab lub zog hluav taws xob electromagnetic los ntawm lub taub hau phom thiab lub qhov them yog 5.52μT. Txawm hais tias tus nqi hluav taws xob siab dua li tus nqi nruab nrab hauv lub tsheb me ntsis, nws qis dua tus qauv ceeb toom hluav taws xob electromagnetic ntawm 100μT, thiab thaum them, khaws qhov deb ntau dua 20 cm ntawm pawg them, thiab lub zog hluav taws xob yuav raug txo kom txog 0.
Raws li qhov teeb meem uas tau hais hauv Is Taws Nem tias kev tsav tsheb fais fab mus sij hawm ntev yuav ua rau cov plaub hau poob, qee cov kws tshaj lij tau taw qhia tias qhov no yuav muaj feem cuam tshuam nrog cov yam xws li kev tsav tsheb mus sij hawm ntev, nyob lig, thiab kev ntxhov siab ntawm lub hlwb, tab sis tej zaum yuav tsis muaj feem cuam tshuam ncaj qha rau kev tsav tsheb fais fab tshiab.
3. Tsis pom zoo: nyob hauv lub tsheb thaum them roj teeb
Txawm hais tias qhov kev pheej hmoo ntawm "kev tawg" tau raug tshem tawm, nws tseem tsis tau pom zoo kom tib neeg nyob hauv lub tsheb thaum them. Qhov laj thawj kuj yooj yim heev. Txawm hais tias kuv lub teb chaws lub tsheb fais fab tshiab thiab cov thev naus laus zis them hluav taws xob tau paub tab heev tam sim no, nws raug txwv los ntawm cov yam ntxwv ntawm lub roj teeb thiab tsis tuaj yeem tshem tawm qhov ua tau ntawm kev kub ntxhov. Tsis tas li ntawd, thaum lub tsheb them, qhib lub tshuab cua txias, siv cov khoom siv lom zem hauv tsheb, thiab lwm yam yuav ncua sijhawm tos them thiab txo qhov ua haujlwm them.
