Dab tsi yog cov hluav taws xob electromagnetic
Peb cov khoom siv hluav taws xob hluav taws xob muaj xws li radar systems, TV thiab tshaj tawm hauv xov tooj cua, xov tooj cua zaus induction thiab nruab nrab cov khoom siv cua sov, xov tooj cua zaus thiab microwave cov khoom siv kho mob, ntau yam khoom siv hluav taws xob, kev sib txuas lus chaw nres tsheb, satellite ntiaj teb kev sib txuas lus chaw nres tsheb, chaw nres tsheb loj fais fab, kis tau tus mob. thiab cov khoom siv hloov pauv, high-voltage thiab ultra-high voltage kis tau tus mob, subway tsheb ciav hlau thiab hluav taws xob tsheb ciav hlau, nrog rau cov khoom siv hauv tsev feem ntau.
Khoos phib tawj, TV, tshuab plaub hau... Cov khoom siv hauv tsev no, uas muaj feem xyuam nrog tib neeg lub neej, txhua tus tsim hluav taws xob hluav taws xob. Piv nrog rau cov khoos phis tawj, cov khoom siv hauv tsev, thiab cov khoom siv hluav taws xob tshaj lij, cov chaw nres tsheb hauv paus tsis yog ib qho ntawm cov hluav taws xob muaj zog dua. Tshwj xeeb tshaj yog raws li daim ntawv thov ntawm cov thev naus laus zis thev naus laus zis, hluav taws xob siv hluav taws xob ntawm 3G mobile kev sib txuas lus tau raug tswj xyuas ntxiv. Raws li kev soj ntsuam kev tso cai, cov hluav taws xob hluav taws xob hluav taws xob ntawm ib txwm siv hluav taws xob ntawm lub laptop yog kwv yees li ntawm cov hluav taws xob ntawm ob lub chaw sib txuas lus. Cov hluav taws xob tso tawm ntawm lub microwave ua haujlwm yog 40 npaug ntawm qhov chaw nres tsheb sib txuas lus.
Qhov siab dua qhov chaw nres tsheb ceev, qhov hluav taws xob me me
Feem ntau siv 2G, tseem hu ua GSM mobile kev sib txuas lus, siv xov tooj ntawm tes. Cov xov tooj ntawm tes thiab lub hauv paus chaw nres tsheb tau txuas nrog ob qho kev qhia los ntawm kev siv hluav taws xob tsis zoo, thiab txhua qhov chaw nres tsheb hauv paus muaj qee yam haujlwm. Txhawm rau kom muaj kev hu xov tooj zoo, nws yog ib qho tsim nyog yuav tsum tsim kom muaj ntau lub hauv paus chaw nres tsheb hauv ntau qhov chaw thiab ua kom muaj teeb meem ntxiv. Thiab tsis ntev los no nrov 3G thev naus laus zis, nws lub hauv paus chaw nres tsheb tiag tiag yog lub tshuab xa hluav taws xob qis, yog lub xov tooj cua tsis tu ncua, feem ntau tsuas yog 5-40 watts, ntau me dua li ntau txhiab watts ntawm cov xov tooj cua xa xov tooj cua. Qee cov pej xeem txhawj xeeb tias ntau lub hauv paus chaw nres tsheb tsim hauv thaj chaw nyob, qhov hluav taws xob ntau dua. Raws li Yeter Anger, tus kws tshaj lij los ntawm Swedish National Radiation Protection Association, tib neeg txoj kev ntxhov siab yog tshwm sim los ntawm kev tsis paub txog cov thev naus laus zis tshiab thiab yog kev nkag siab yuam kev hauv lawv txoj kev nkag siab. Qhov tseeb, qhov siab dua qhov ceev ntawm lub hauv paus chaw nres tsheb, qhov qis dua lub zog xa los ntawm lub hauv paus chaw nres tsheb. Lub caij no, qhov ze rau qhov chaw nres tsheb hauv paus, qhov qis dua qhov kev sib kis ntawm lub xov tooj ntawm tes. Qhov ntawd yog hais tias, ntau lub hauv paus chaw nres tsheb tau tsim, cov neeg hluav taws xob tsawg tau txais los ntawm cov khoom siv hauv xov tooj. Vim lub hauv paus chaw nres tsheb yog tuab, cov teeb liab kev sib txuas lus yuav zoo dua, yog li cov xov tooj ntawm tes tsis tas yuav ua hauj lwm nyuaj los tso cov teeb liab. Nws zoo li nyob rau hauv ib qho chaw tshwj xeeb, thaum ob tug neeg tham nyob ze ua ke, lawv tuaj yeem hnov ntau yam tsis tas yuav qw nrov. Feem ntau hais lus, tib neeg tsis tas yuav txhawj xeeb txog qhov tsis zoo ntawm hluav taws xob ntawm tib neeg lub cev thaum lawv nyob deb 1-3 meters deb ntawm qhov chaw nres tsheb 3G.
