Umsindo wefoni weselula: Ukulinganisa kokuphepha kumafoni weselula angu-1 000

I-EWG engeyona inzuzo inikeza umhlahlandlela wamahhala, ophelele wokuhlola ingozi yakho yomlilo

I-T-Mobile myTouch 3G ngesistimu yokusebenza ye-Android , ephikisana ngokumelene ne- iPhone 3G S ye-AT & T ne- Palm Pre for Sprint, inezinga eliphezulu lemisebe yefoni yeselula kunoma iyiphi i-handset entsha, elula- ukuguqula umthengi umhlahlandlela of 1,000 cell phone kanye Smartphones.

Lokho kubamba umbuzo omkhulu kumakhalekhukhwini osisebenzisayo manje noma mayelana nokuthenga: Ingabe amaselula aphephile noma adala umdlavuza? Yiminye yemibuzo endala kunazo zonke encwadini yefoni yeselula esingenayo impendulo eqondile.

Izindaba ezinhle ukuthi abacwaningi baqhubeka nokuqhuma izifundo futhi bashise ngemali (futhi bacele imali eyengeziwe ) ukuthola izimpendulo ezicacile.

Kodwa njengokudla kufanele kubhalwe ngamaqiniso okunomsoco, ukuphikisana okufanayo kungenziwa ukuthi amakholi omakhalekhukhwini afanele abhale ukukhishwa kwama-radiation.

Phakathi naleso sikhathi, okungenani sinezinga elijwayelekile lapho imisebe yocingo ilinganiswa futhi ngezinye izikhathi ibikwa. Ibizwa ngokuthi i- SAR , eqondene nesilinganiso esithile sokumamatheka .

ENyakatho Melika, ukulinganisa kwe-SAR yocingo kulinganiswa phakathi kuka-0.0 no-1.60 no-1.60 obekwe yi-Federal Communications Commission (FCC) njengoba izinga eliphezulu lemisebe livumelekile.

Ukusebenzisa izinga le-SAR lokulinganisa, manje sinenhlangano engeyona inzuzo ebizwa ngokuthi i-Environmental Working Group (EWG) eyashicilele ukubika okubalulekile kokungena komthengi ku-intanethi ngaphezu kwamafoni angu-1 000 , ama-PDA kanye nama-smartphones ngokuthi bangakanani ama-radiation abaphuma kuwo.

I-EWG, ngendlela, yiqembu elifanayo elishicilela isisekelo sezinsiza zokuphepha ze-Skin Deep cosmetic database.

"Sithanda ukukhuluma ukuthi amafoni omakhalekhukhwini aphephile," kusho usosayensi omkhulu we-EWG kanye nomlobi ocwaningayo u-Olga Naidenko, uF.D. "Kodwa asikwazi. Isayensi yakamuva kakhulu - ngenkathi ingaqiniseki - iphakamisa izinkinga ezinkulu mayelana nengozi yomdlavuza yokusetshenziswa kweselula okufanele iqondiswe ngokucwaninga okuqhubekayo. [Kodwa thina] singathatha izinyathelo zokunciphisa ukuchayeka [manje]. "

Ngabantu abayizigidi eziyizinkulungwane ezine emhlabeni okhuluma ngamafoni noma amaphesenti angama-60 wabantu bomhlaba (ngokusho kwe-EWG), ababhalisile abangenantambo abangama-270.3 e-US noma amaphesenti angu-87 aseMelika kusukela ngoDisemba 2008 (ngokusho kwe-CTIA) nakamuva Ucwaningo oluthola "izingozi eziphakeme kakhulu zobuchopho nobuchopho phakathi kwabantu abasebenzisa umakhalekhukhwini iminyaka engama-10 noma ngaphezulu," umbuzo wokubheka kwakho kubalulekile futhi uyazi.

Isilinganiso Sakho Sefoni Esingakanani? Ukukhuluma ngomakhalekhukhwini wakho akufani nokuba ne-X ray. Ukuze ulinganise izinga lakho lokushisa imisebe, manje ungabheka ifoni yakho phezulu kumhlahlandlela we-EWG ukuze wazi ukuthi ukhuluma ngaphandle kwe-SAR ephakeme (hhayi ekhethekayo) noma i-SAR ephansi (ekhethekayo).

Ngenkathi abanye abathwali befoni behlonza lolu lwazi lwe-SAR (okungukuthi i-Verizon Wireless yenza lokhu kuhle), okwamanje akunawo mgangatho kuwo wonke umkhakha ngoba akuzange kube khona isenzo sikahulumeni sokuwudinga. Abanye abathwali bahlukanisa ulwazi futhi abanye abakwenzi. Kodwa i-EWG iqoqe amafoni angama-1,000 namazinga e-SAR endaweni eyodwa.

I-T-Mobile myTouch 3G, isibonelo, inezinga eliphakeme lemisebe ye-1.55 W / kg uma ligcinwe endlebeni, i-EWG ithi ngokusho komkhiqizi wefoni. Lezinga le-SAR lingaphansi kancane ngaphansi kwe-FCC-eligunyaziwe ngokomthetho esiphezulu futhi kungaba nokukhathazeka kwabathengi.

Ngokuphambene nalokho, isilinganiso se-SAR esincane kakhulu sefoni ngomhlahlandlela we-EWG yi-Samsung Impression (SGH-a877) ye-AT & T, enezinga eliphezulu le-SAR lika-0.35 W / kg uma ligcinwe endlebeni, i-EWG ithi ngokusho umkhiqizi wefoni.

I-EWG ithi ama-iPhone 3G S amazinga aphakeme kakhulu angu-1.19 W / kg namazinga wePalm Pre nge-0.92 W / kg ephansi.

Umhlahlandlela we-radiation cell phone e-EWG waphila bukhoma ngo-Septhemba 9, 2009 ngale nhloso:

"E-EWG, ithimba lethu labososayensi, ochwepheshe, ochwepheshe bezinqubomgomo, abameli kanye nabahleli bekhompiyutha baxhaphaza idatha kahulumeni, amadokhumende omthetho, izifundo zesayensi kanye nezivivinyo zethu zelabhoratory ukuveza izinsongo empilweni yakho nasemvelo nokuthola izixazululo. Ucwaningo lwethu luveza ukungaqinisekisi amaqiniso onelungelo lokukwazi. "

Ngesikhathi silinde izimpendulo ezicacile zokubhekana nokuphepha kwefoni nomsakazo, inhloso yomhlahlandlela we-EWG ukusiza abathengi bakhethe amafoni ngamanqanaba aphansi e-SAR.

Ama-cell phone aphezulu angu-10 aphezulu kakhulu e-EWG kanye nama-smartphones (anezintambo eziphansi) angatholakala ngezansi kanye ne-10 ephezulu kunazo zonke (nge-radiation ephezulu). Lezi ziphathekayo zihlelwe kusukela kokuhle kuya ezibi kakhulu ohlwini oluhle kakhulu futhi ziqale ngobubi kakhulu ohlwini olubi kakhulu.

Ngaphezu kokwazi ukulinganiswa kwe-SAR yakho yamanje noma entsha yeselula, i-EWG iphinde ituse amathiphu ayisishiyagalombili wokuphepha ukukusiza kalula futhi wehlise kalula ukuvezwa kwemisebe yefoni yakho. Nawa amanye amathiphu ayisihlanu nakwaBarton Publishing.

Umhlahlandlela we-EWG ikuvumela ukuba useshe ukwenza kwakho okwenziwe kanye nemodeli - uma nje kusekudatsheni yabo - futhi ungathola futhi amafoni ngomakhalekhukhwini nomenzi womakhalekhukhwini. Ungakwazi ukufinyelela umhlahlandlela we-EWG ogcwele wesikhala somakhalekhukhwini lapha .
