Njengoko iteknoloji idityaniswa ngakumbi kubomi bethu bemihla ngemihla, iinkxalabo malunga nemitha ye-electromagnetic radiation (EMR) evela kwizixhobo zombane ziyakhula. Ukutshintshwa kwenethiwekhi yinxalenye ebalulekileyo kuthungelwano lwanamhlanje kwaye akukho nto. Eli nqaku lixoxa malunga nokuba iiswitshi zothungelwano zikhupha imitha, amanqanaba emitha enjalo, kunye nefuthe kubasebenzisi.
Yintoni imitha ye-electromagnetic?
Imitha ye-electromagnetic radiation (EMR) ibhekisa kumandla ahamba esithubeni ngendlela yamaza ombane. La maza ayahluka ngokuphindaphindiweyo kwaye aquka amaza erediyo, ii-microwaves, i-infrared, ukukhanya okubonakalayo, i-ultraviolet, i-X-reyi, kunye nemitha ye-gamma. I-EMR ngokuqhelekileyo yahlulahlulwe ibe yimitha ye-ionizing (imitha ephezulu yamandla enokubangela umonakalo kwizicubu zebhayoloji, njenge-X-reyi) kunye nemitha ye-non-ionizing (amandla asezantsi angenawo amandla aneleyo okwenza i-athomu okanye iimolekyuli, ezinjengamaza onomathotholo. kunye nee-oveni ze-microwave).
Ngaba iiswitshi zenethiwekhi zikhupha imitha ye-electromagnetic?
Ukutshintsha kwenethiwekhi sisixhobo sombane esisetyenziselwa ukudibanisa izixhobo ezahlukeneyo ngaphakathi kwenethiwekhi yendawo yendawo (LAN). Njengoninzi lwezixhobo zombane, iiswitshi zenethiwekhi zikhupha inqanaba elithile lemitha ye-electromagnetic. Nangona kunjalo, kubalulekile ukwahlula phakathi kohlobo lwemitha ekhutshwayo kunye neziphumo zayo ezinokubakho empilweni.
1. Uhlobo lwemitha yokutshintsha kwenethiwekhi
Imitha ekwinqanaba elisezantsi le-non-ionizing radiation: Ukutshintsha kwenethiwekhi ikakhulu kukhupha imitha yemitha ekwinqanaba elisezantsi le-non-ionizing, kubandakanywa imitha yerediyo yerediyo (RF) kunye nemitha ephantsi kakhulu (ELF). Olu hlobo lotshiso lwemitha luyafana nolo lukhutshwa zii-electronics ezininzi zekhaya kwaye alunamandla ngokwaneleyo okufaka i-athomu ye-ionize okanye yenze umonakalo othe ngqo kwiithishu zebhayoloji.
I-Electromagnetic Interference (EMI): Izitshixo zenethiwekhi zinokuvelisa ukuphazamiseka kwe-electromagnetic (EMI) ngenxa yeempawu zombane eziziphetheyo. Nangona kunjalo, iiswitshi zenethiwekhi zanamhlanje ziyilelwe ukunciphisa i-EMI kwaye zihambelane nemigangatho yoshishino ukuqinisekisa ukuba azibangeli ukuphazamiseka okukhulu kwezinye izixhobo.
2. Amanqanaba emitha kunye nemigangatho
Ukuthobela imigangatho yokhuseleko: Ukutshintshwa kwenethiwekhi kuxhomekeke kwimigangatho yolawulo ebekwe yimibutho efana ne-Federal Communications Commission (FCC) kunye ne-International Electrotechnical Commission (IEC). Le migangatho iqinisekisa ukuba izixhobo zombane, kubandakanywa iiswitshi zenethiwekhi, zisebenza ngaphakathi kwemida ekhuselekileyo yemitha ye-electromagnetic radiation kwaye azibeki mngcipheko wezempilo.
Ukuvezwa kwemitha ephantsi: Ukutshintsha kwenethiwekhi ngokuqhelekileyo kukhupha amanqanaba aphantsi kakhulu emitha yombane xa kuthelekiswa neminye imithombo yemitha yemitha yombane, efana neeselfowuni kunye neerutha zeWi-Fi. Imitha yayingaphakathi kwimida ekhuselekileyo ebekwe yimigaqo yamazwe ngamazwe.
iziphumo zempilo kunye nokhuseleko
1. Uphando kunye noFundo
I-non-ionizing Radiation: Uhlobo lwemitha yemitha ekhutshwe ngokutshintsha kwenethiwekhi iwela phantsi koluhlu lwemitha ye-non-ionizing kwaye ayizange idibaniswe nemiphumo emibi yempilo kuphando lwezenzululwazi. Izifundo ezibanzi kunye nokuphononongwa yimibutho efana ne-World Health Organization (WHO) kunye ne-International Agency for Research on Cancer (IARC) ayifumananga ubungqina obuqinisekileyo bokuthi amanqanaba aphantsi emitha ye-non-ionizing evela kwizixhobo ezifana nokutshintsha kwenethiwekhi kubangela ingozi enkulu yempilo.
Izilumkiso: Nangona imvumelwano yangoku kukuba i-radiation ye-non-ionizing evela kwi-network switch ayinabungozi, ihlala iqiqile ukulandela iindlela zokhuseleko ezisisiseko. Ukuqinisekisa ukungena komoya okufanelekileyo kwezixhobo zombane, ukugcina umgama ofanelekileyo ukusuka kwisixhobo sombane esixinana kakhulu, kunye nokulandela izikhokelo zomenzi kunganceda ukunciphisa nakuphi na ukuvezwa okunokwenzeka.
2. Ulawulo lolawulo
Ii-Arhente eziLawulayo: Ii-arhente ezifana neFCC kunye ne-IEC zilawula kwaye zibeke esweni izixhobo zombane ukuqinisekisa ukuba ziyayifezekisa imigangatho yokhuseleko. Ukutshintsha kwenethiwekhi kuyavavanywa kwaye kuqinisekiswe ukuqinisekisa ukuba ukukhutshwa kwemitha kungaphakathi kwemida ekhuselekileyo, ekhusela abasebenzisi kwiingozi ezinokubakho.
ukuququmbela
Njengezixhobo ezininzi zombane, iiswitshi zenethiwekhi zikhupha inqanaba elithile lemitha ye-electromagnetic, ngokuyintloko ngohlobo lwemitha ye-non-ionizing ephantsi. Nangona kunjalo, le mitha yemitha iphakathi kwemida ekhuselekileyo ebekwe yimigangatho yolawulo kwaye ayizange inxulunyaniswe nemiphumo emibi yempilo. Abasebenzisi banokusebenzisa utshintsho lwenethiwekhi njengenxalenye yenethiwekhi yekhaya okanye ishishini ngokuzithemba, besazi ukuba izixhobo zenzelwe ukusebenza ngokukhuselekileyo nangokufanelekileyo. E-Todahike, sizimisele ukubonelela ngezisombululo zenethiwekhi ezikumgangatho ophezulu ezihambelana nemigangatho yokhuseleko, ukuqinisekisa ukusebenza okuthembekileyo kunye noxolo lwengqondo kubathengi bethu.
