Mafoni a Maselo a Maselo: Kutetezedwa Malingaliro pa Mafoni Amtundu 1,000

EWG yopanda phindu ikupereka mndandanda waulere, wowonjezera kuti muone momwe chiopsezo chanu chikuyendera

T-Mobile myTouch 3G ndi Android Android opaleshoni dongosolo , amene amatsutsana mwamphamvu motsutsana iPhone 3G S ya AT & T ndi Palm Pre for Sprint, ali ndi kachiwiri pafoni foni miyendo yamtundu uliwonse m'manja, watsopano- kutsegula wogula makasitomala 1,000 ndi mafoni.

Izi zikupempha funso lalikulu pa foni yomwe mukugwiritsa ntchito tsopano kapena pafupi kugula: Kodi mafoni a m'manja ndi otetezeka kapena amachititsa khansa? Ndilo limodzi la mafunso akale kwambiri mu bukhu la foni yam'manja limene ife tiribe yankho lomaliza.

Nkhani yabwino ndi yakuti ochita kafukufuku akupitiriza kufufuza maphunziro ndikuwotcha ndalama ( ndikupempha ndalama zambiri ) kuti mupeze mayankho ogwira mtima.

Koma monga chakudya chiyenera kulembedwa ndi zowonjezera zakudya, lingaliro lomwelo lingapangidwe kuti mafoni a m'manja ayenera kulemba momwe akugwiritsira ntchito mankhwalawa.

Padakali pano, ife timakhala ndi muyezo umene mawonekedwe a foni amawonetsera ndipo nthawi zina amawafotokozera. Icho chimatchedwa SAR , chomwe chimaimira kuchuluka kwake kwa kuyamwa .

Ku North America, mlingo wa SAR wa foni umayesedwa pakati pa 0.0 ndi 1.60 ndi 1.60 yokhazikitsidwa ndi Federal Communications Commission (FCC) ngati msinkhu wa ma radiation umaloledwa.

Pogwiritsa ntchito muyeso wa SAR, tsopano tili ndi bungwe lopanda phindu lomwe limatchedwa Environmental Working Group (EWG) lomwe lafalitsa mauthenga ofunikira okhudzana ndi ogula makasitomala oposa 1,000 , PDAs ndi mafoni omwe amawatulutsa.

EWG, mwa njira, ndi gulu lomwelo lomwe limasindikiza malo othandizira chitetezo cha Skin Skin cosmetic security database.

"Tikufuna kunena kuti mafoni a m'manja ndi otetezeka," anatero wolemba sayansi wamkulu wa EWG ndi wolemba mabuku wolemba mabuku Olga Naidenko, Ph.D. "Koma sitingathe. Sayansi yatsopano - posagwirizana - imabweretsa mavuto akuluakulu okhudzana ndi khansa ya kugwiritsira ntchito foni yomwe iyenera kuyendetsedwa kudzera mu kufufuza kwina. [Koma ife] tingatenge masitepe kuti tipewe kuyang'ana [tsopano]. "

Ndili ndi anthu 4 biliyoni padziko lapansi akulankhula pafoni zam'manja kapena 60 peresenti ya anthu padziko lapansi (malinga ndi EWG), olemba ma wireless 270.3 miliyoni ku US kapena 87 peresenti ya a ku America monga Dec. 2008 (malinga ndi CTIA) ndi posachedwapa kufufuza "kupeza" ngozi zoopsa kwambiri za ubongo ndi zopweteka zamatenda pakati pa anthu omwe amagwiritsa ntchito mafoni a m'manja kwa zaka khumi kapena kuposerapo, "funso la kuwonetsetsa kwanu ndilofunika komanso lodziwika bwino.

Kodi Mafoni Anu Am'manja Amakhala Bwanji? Kuyankhula pa foni yanu sikumakhala ndi X-ray. Komabe, kuti muwone ngati mumakhala ndi ma radiation, tsopano mukhoza kuyang'ana foni yanu pa tsamba la EWG kuti mudziwe ngati mukukwera pa SAR (osati yabwino) kapena pansi (SAR).

Ngakhale ogwira ntchito zam'manja akulemba mndandanda wa SAR uwu (mwachitsanzo, Verizon Wireless amachita izi bwino), pakali pano palibe zofunikira pamsika chifukwa palibe pulogalamu ya boma yomwe imafuna kuti ichitike. Ena ogulitsa amaletsa nkhaniyo ndipo ena samatero. Koma EWG yasonkhanitsa mafoni oposa 1,000 ndi ma SAR awo pamalo amodzi.

Mwachitsanzo, T-Mobile myTouch 3G, ili ndi mlingo wokwanira wa 1,55 W / kg pamene wagwiritsidwa khutu, EWG imanena molingana ndi wopanga mafoni. Mbali iyi ya SAR imangokhala pang'ono pansi pa malamulo a FCC ovomerezedwa ndi malamulo ndipo ikhoza kudetsa nkhaŵa kwa ogula.

Mosiyana ndiyi, mlingo wotsika kwambiri wa SAR wa foni yam'tsogoleli wa EWG ndi Samsung Impression (SGH-a877) ya AT & T, yomwe ili ndi mlingo wapamwamba wa SAR wa 0.35 W / kg pamene wagwiritsidwa khutu, EWG ikunena molingana ndi wopanga mafoni.

EWG imati mitengo ya iPhone 3G S pamtunda wapamwamba kwambiri 1.19 W / kg ndi mitengo ya Palm Pre pamunsi wa 0,92 W / kg.

Mtsinje wa EWG wotsogoleredwa ndi mafoni a pa Intaneti unakhalapo pa Sept. 9, 2009 ndi ntchito iyi:

"Pa EWG, gulu lathu la asayansi, akatswiri, akatswiri a ndondomeko, olemba milandu ndi makompyuta amapanga deta za boma, zolemba zalamulo, zofufuza za sayansi ndi ma laboratory athu omwe amayesa kuopseza thanzi lanu ndi chilengedwe komanso kupeza njira zothetsera mavuto. Kufufuza kwathu kumabweretsa kusokoneza mfundo zomwe muli ndi ufulu wodziwa. "

Pamene tikudikirira mayankho ogwira mtima okhudza kutetezedwa kwa foni ndi ma radiation, cholinga cha EWG chitsogozo ndicho kuthandiza ogula kusankha mafoni a m'manja ndi ma SAR otsika.

Mafoni apamwamba kwambiri a EWG ndi mafoni a m'manja (omwe ali ndi ma radiation otsika) angapezeke m'munsimu pamodzi ndi 10 pamwamba (ndi ma radiation). Manambalawa amalembedwa kuyambira zabwino kwambiri mpaka polemba bwino kwambiri ndikuyamba ndi zovuta kwambiri m'gululi.

Kuwonjezera pa kudziwa SAR yanu yamakono kapena yatsopano, EWG imalangizanso malangizo asanu ndi atatu otetezeka kuti athe kukuthandizani mosavuta komanso mwamsanga kuchepetsa kuwala kwa foni. Nawa malangizowo ena asanu kuchokera ku Barton Publishing.

Buku la EWG likukuthandizani kuti mufufuze kupanga ndi machitidwe anu enieni - malinga ndi zomwe zili mumasitomala awo - ndipo mutha kupeza mafoni a m'manja ndi wothandizira foni ndi wopanga mafoni. Mukhoza kupeza mauthenga onse a EWG omwe amawotcha ma foni pano .
