T-Mobile myTouch 3G le tsamaiso ea Android ea tsamaiso ea Android , e loantšanang haholo le iPhone 3G S bakeng sa AT & T le Palm Pre for Sprint, e na le boemo ba bobeli ba mahlaseli a selefouno ba selefouno leha e le efe, ho tataisa batho ba liselefouno tse 1 000 le li-smartphone.
Seo se kopa potso e kholo ka fono eo u e sebelisang hona joale kapa ea ho reka: Na liselefouno li sireletsehile kapa li baka kankere? Ke e 'ngoe ea lipotso tsa khale ka ho fetisisa bukeng ea selefouno eo re sa ntseng re e-na le karabo e tiileng.
Litaba tse monate ke hore bafuputsi ba tsoelapele ho phenya lithuto le ho chesa ka chelete (le ho batla chelete e eketsehileng ) ho fumana likarabo tse nepahetseng.
Empa feela joalokaha lijo li tlameha ho ngoloa ka linnete tse nang le phepo, ho ka etsoa phehisano e tšoanang hore liselefouno li lokela ho thathamisa lihlahisoa tsa bona tsa mahlaseli.
Khabareng, bonyane re na le tekanyetso eo meriana ea selefouno e lekantsoang ka eona 'me ka linako tse ling e tlalehoa. E bitsoa SAR , e bolelang litekanyetso tse khethehileng tsa ho nkoa .

Re sebelisa litekanyetso tsa tekanyo ea SAR, hona joale re na le mokhatlo o se nang phaello o bitsoang Environmental Working Group (EWG) o phatlalalitseng tlaleho ea bohlokoa ea ho fana ka litlaleho tsa bareki ho feta 1 000 liselefouno, li-PDA le li-smartphone tse bontšang hore na mahlaseli a mangata a tsoang hokae.
EWG, ka tsela, ke sehlopha se le seng se phatlalatsang letšoao le thusang la Letšoao la Tšireletso ea Letlalo la Bohlokoa ba Skin Deep.
"Re lakatsa ho tseba hore liselefouno li bolokehile," ho boletse rasaense ea phahameng ea EWG le mohlophisi oa thuto ea etellang pele Olga Naidenko, Ph.D. "Empa re ke ke ra khona.

[Empa re] re nka mehato ea ho fokotsa ts'oaetso [hona joale]. "
Ho na le batho ba limilione tse likete tse 4 lefatšeng ba buang ka liselefouno kapa karolo ea 60 lekholong ea baahi ba lefatse (ho ea ka EWG), ba ngolisitseng li-wireless ba limilione tse 270,3 ba US kapa karolo ea 87 lekholong ea Maamerika ho fihlela ka Phato 2008 (ho ea ka CTIA) le morao tjena liphuputso tsa ho fumana "likotsi tse phahameng ka ho fetisisa tsa boko ba 'mele le matšoao a liphatsa tsa lefutso har'a batho ba sebelisang liselefouno bakeng sa lilemo tse 10 kapa ho feta," potso ea ho pepeseha ha hao ke ea bohlokoa ebile e tsebahala.
Mohala oa hau oa cellular o hokae? Ho bua ka selefouno ea hau ha ho tšoane le ho ba le X-ray. Leha ho le joalo, ho lekanyetsa boemo ba mahlaseli a hao, joale u ka sheba mohala oa hao ka mohala oa mahlaseli oa EWG e le hore u tsebe hore na u ntse u qoqa le SAR e phahameng (e sa rateheng) kapa e tlaase SAR (e ka khethollang).
Le hoja ba bang ba tsamaisang thepa ea selefouno ba thathamisa tlhahisoleseding ena ea SAR (ke hore Verizon Wireless e etsa sena hantle), hona joale ha ho na maemo a holimo ho indasteri hobane ha ho e-s'o be le ketso ea mmuso ea ho e hloka. Bajari ba bang ba senola tlhahisoleseding mme ba bang ha ba e tsebe. Empa EWG e kopantsitse liselefouno tse 1 000 le litekanyetso tsa bona tsa SAR sebakeng se le seng.
Ka mohlala, T-Mobile myTouch 3G, e na le tekanyo e phahameng ea mahlaseli a 1,55 W / kg ha e tšoaroa tsebe, EWG e re ho ea ka moetsi oa fono. Ts'ebetso ena ea SAR e hanyenyane feela ka tlase ho molao oa molao oa FCC 'me o ka ameha ka bareki.
Ka lehlakoreng le leng, tekanyo e tlaase ka ho fetisisa ea SAR bakeng sa selefouno ea tataiso ea EWG ke Samsung Impression (SGH-a877) bakeng sa AT & T, e nang le boholo ba SAR ea 0.35 W / kg ha e tšoareloa tsebe, EWG e re ho ea ka moetsi oa thelefono.
EWG e re litefiso tsa iPhone 3G S li ka holimo ho 1,19 W / kg le lipalo tsa Palm Pre ka tlaase ho 0,92 W / kg.
Moeletsi oa mahlaseli oa mohala oa EWG oa inthanete o ile oa phela ka la 9 Phupu 2009, ka thōmo ena:
