Raws li thev naus laus zis tau koom ua ke hauv peb lub neej niaj hnub, kev txhawj xeeb txog hluav taws xob hluav taws xob hluav taws xob (EMR) los ntawm cov khoom siv hluav taws xob tau loj hlob. Network keyboards yog ib qho tseem ceeb hauv cov tes hauj lwm niaj hnub thiab tsis muaj kev zam. Kab lus no tham txog seb lub network hloov pauv hluav taws xob, theem ntawm cov hluav taws xob li cas, thiab qhov cuam tshuam rau cov neeg siv.
electromagnetic tawg yog dab tsi?
Electromagnetic hluav taws xob (EMR) yog hais txog lub zog taug kev los ntawm qhov chaw nyob rau hauv daim ntawv ntawm electromagnetic tsis. Cov nthwv dej no sib txawv hauv cov zaus thiab suav nrog cov xov tooj cua, microwaves, infrared, pom lub teeb, ultraviolet, X-rays, thiab gamma rays. EMR feem ntau muab faib ua ionizing hluav taws xob (lub zog hluav taws xob siab uas tuaj yeem ua rau puas tsuaj rau cov ntaub so ntswg, xws li X-rays) thiab tsis-ionizing hluav taws xob (qis zog uas tsis muaj zog txaus rau ionize atoms lossis molecules, xws li xov tooj cua tsis muaj zog. thiab microwave qhov cub).
Puas yog network keyboards emit electromagnetic tawg?
Lub network hloov yog ib qho khoom siv hluav taws xob siv los txuas ntau yam khoom siv hauv ib cheeb tsam hauv cheeb tsam network (LAN). Zoo li feem ntau cov khoom siv hluav taws xob, cov hloov pauv hauv lub network ua rau qee theem ntawm hluav taws xob hluav taws xob. Txawm li cas los xij, nws yog ib qho tseem ceeb kom paub qhov txawv ntawm hom hluav taws xob tawm thiab nws cov kev cuam tshuam rau kev noj qab haus huv.
1. Radiation hom hloov network
Tsawg-theem tsis-ionizing hluav taws xob: Network hloov feem ntau tawm cov hluav taws xob qis qis, suav nrog xov tooj cua zaus (RF) hluav taws xob thiab tsis tshua muaj zaus (ELF) hluav taws xob. Hom hluav taws xob no zoo ib yam li cov khoom siv hluav taws xob hauv tsev thiab tsis muaj zog txaus rau ionize atoms lossis ua rau muaj kev puas tsuaj rau cov ntaub so ntswg.
Electromagnetic Interference (EMI): Cov keyboards hauv network kuj tuaj yeem tsim hluav taws xob cuam tshuam (EMI) vim hluav taws xob teeb liab lawv ua. Txawm li cas los xij, cov kev hloov pauv niaj hnub no tau tsim los txo qis EMI thiab ua raws li cov qauv kev lag luam kom ntseeg tau tias lawv tsis ua rau muaj kev cuam tshuam loj rau lwm yam khoom siv.
2. Cov qib hluav taws xob thiab cov qauv
Ua raws li cov qauv kev nyab xeeb: Kev hloov pauv hauv lub network yog raws li cov txheej txheem tswj hwm los ntawm cov koom haum xws li Tsoom Fwv Teb Chaws Kev Sib Txuas Lus (FCC) thiab International Electrotechnical Commission (IEC). Cov qauv no xyuas kom meej tias cov khoom siv hluav taws xob, suav nrog cov hloov pauv hauv lub network, ua haujlwm nyob rau hauv qhov txwv tsis pub muaj hluav taws xob hluav taws xob hluav taws xob thiab tsis ua rau muaj kev phom sij rau kev noj qab haus huv.
Tsawg Radiation Exposure: Network keyboards feem ntau tso tawm cov hluav taws xob tsawg heev piv rau lwm qhov chaw ntawm hluav taws xob hluav taws xob, xws li xov tooj ntawm tes thiab Wi-Fi routers. Cov hluav taws xob tau zoo nyob rau hauv kev nyab xeeb txwv los ntawm cov txheej txheem thoob ntiaj teb.
cov teebmeem kev noj qab haus huv thiab kev nyab xeeb
1. Kev Tshawb Fawb thiab Kev Tshawb Fawb
Tsis-Ionizing Radiation: Hom hluav taws xob tawm los ntawm kev hloov pauv hauv lub network poob rau hauv qeb ntawm cov hluav taws xob uas tsis yog-ionizing thiab tsis tau txuas rau cov teebmeem kev noj qab haus huv hauv kev tshawb fawb tshawb fawb. Kev tshawb fawb dav dav thiab kev tshuaj xyuas los ntawm cov koom haum xws li World Health Organization (WHO) thiab Lub Chaw Haujlwm Saib Xyuas Kev Noj Qab Haus Huv Hauv Ntiaj Teb rau Kev Tshawb Fawb Txog Kev Mob Cancer (IARC) tsis tau pom cov pov thawj uas ntseeg tau tias qis qis ntawm cov hluav taws xob tsis muaj hluav taws xob los ntawm cov khoom siv xws li kev hloov pauv hauv lub network ua rau muaj kev phom sij loj.
Kev ceev faj: Thaum qhov kev pom zoo tam sim no yog tias tsis yog-ionizing hluav taws xob los ntawm kev hloov pauv hauv lub network tsis muaj teeb meem, nws yog ib txwm ua tib zoo ua raws li kev coj ua kev nyab xeeb. Ua kom muaj qhov cua kom zoo ntawm cov khoom siv hluav taws xob, tswj qhov kev ncua deb ntawm cov khoom siv hluav taws xob uas muaj qhov ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntim cov khoom siv hluav taws xob ua kom zoo, tswj kom muaj kev sib nrug deb ntawm cov khoom siv hluav taws xob zoo, thiab ua raws li cov txheej txheem tsim khoom tuaj yeem pab txo qis qhov tshwm sim.
2. Kev saib xyuas
Cov Txheej Txheem Kev Cai: Cov koom haum xws li FCC thiab IEC tswj hwm thiab saib xyuas cov khoom siv hluav taws xob kom ntseeg tau tias lawv ua tau raws li cov qauv kev nyab xeeb. Network keyboards raug kuaj thiab ntawv pov thawj los xyuas kom meej tias lawv cov hluav taws xob emissions nyob rau hauv kev nyab xeeb txwv, tiv thaiv cov neeg siv los ntawm tej yam txaus ntshai.
nyob rau hauv xaus
Zoo li ntau cov khoom siv hluav taws xob, cov kev hloov pauv hauv lub network tau tso tawm qee theem ntawm cov hluav taws xob hluav taws xob hluav taws xob, feem ntau nyob rau hauv daim ntawv ntawm cov hluav taws xob qis uas tsis yog-ionizing. Txawm li cas los xij, qhov hluav taws xob no tau zoo nyob rau hauv cov kev txwv kev nyab xeeb uas tau teev tseg los ntawm cov qauv kev tswj hwm thiab tsis tau cuam tshuam rau cov teebmeem kev noj qab haus huv. Cov neeg siv tuaj yeem siv cov hloov pauv hauv lub network ua ib feem ntawm lawv lub tsev lossis kev lag luam network nrog kev ntseeg siab, paub tias cov khoom siv tau tsim los ua haujlwm ruaj ntseg thiab ua haujlwm tau zoo. Ntawm Todahike, peb tau cog lus los muab cov kev daws teeb meem zoo hauv network uas ua raws li cov qauv kev ruaj ntseg, ua kom ntseeg tau tias kev ua tau zoo thiab kev thaj yeeb nyab xeeb rau peb cov neeg siv khoom.
