Lub zog ntawm electromagnetic radiation thiab lub teb chaws cov qauv
Raws li lub tswv yim ntawm hluav taws xob hluav taws xob hluav taws xob, hluav taws xob hluav taws xob hluav taws xob yog ib hom hluav taws xob, thiab nws qhov cuam tshuam rau ib puag ncig feem ntau yog nyob ntawm lub zog ntawm lub zog. Qhov seem ntawm nws qhov kev siv feem ntau suav nrog lub zog ceev, lub zog hluav taws xob, thiab lub zog sib nqus induction.
Lub zog ceev: yog hais txog lub zog hluav taws xob ntau zaus tau txais lossis tso tawm ib lub sijhawm thiab chav tsev, ntsuas hauv watts ib square meter (W / m2). Thaum ntsuas cov hluav taws xob hluav taws xob hluav taws xob ntau zaus ib puag ncig, lub zog ntom ntom feem ntau qhia hauv microwatts ib square centimeter (μ W / cm2).
Sib nqus induction siv: sawv cev rau qhov sib nqus flux rau ib chav tsev ntim lossis cheeb tsam, siv los piav txog lub zog ntawm lub zog ntawm cov hlau nplaum, ntsuas hauv Tesla lossis Gauss (T lossis Gs).
Cov teebmeem lom neeg tshwm sim los ntawm hluav taws xob hluav taws xob hluav taws xob muaj feem cuam tshuam nrog kev siv hluav taws xob hluav taws xob hluav taws xob, lub sijhawm irradiation, zaus ntawm hluav taws xob nthwv dej, thiab lub cev ntev ntawm cov kab mob.
Txhawm rau tswj cov pa phem ntawm electromagnetic nthwv dej ntawm ib puag ncig, tiv thaiv tib neeg txoj kev noj qab haus huv, thiab txhawb kev tsim cov tshuab electromagnetic, Tuam Tshoj tau tsim "National Standard for Environmental Electromagnetic Wave Health Standards of the People's Republic of China" thiab "GB{{ 0}}". Feem ntau, hluav taws xob teb lub zog V / m thiab lub zog ceev μ W / cm2 yog siv los ua units.
Tsoomfwv Suav yeej ib txwm muab qhov tseem ceeb rau kev nyab xeeb rau pej xeem thiab tau tshaj tawm "Txoj Cai Tiv Thaiv Hluav Taws Xob Hluav Taws Xob" (GB8702-88). Cov txheej txheem hluav taws xob hluav taws xob hluav taws xob txwv tau teev tseg hauv txoj cai no yog nruj dua li cov qauv thoob ntiaj teb (saib Table 1, feem ntau yog siv hauv ntu RF), thiab tus qauv txwv tau teeb tsa ntawm 40 μ W / cm2.
Thoob ntiaj teb, cov qauv hluav taws xob txwv rau lub zog ntau zaus (xws li zaus 50Hz) feem ntau yog teem rau ntawm 0.4 micro Tesla (μ T).
Los ntawm Table 1, nws tuaj yeem pom tias cov qauv hluav taws xob pej xeem txwv tsis pub nyob hauv Suav teb tsuas yog 40 μ W / cm2, uas yog ntau tshaj 10 zaug nruj dua li Pawg Neeg Saib Xyuas Kev Ncaj Ncees ntawm Tsis yog Ionizing Radiation thiab EU cov qauv hauv tebchaws, thiab 5 zaug nruj dua Australia tus qauv.
