手機(jī)輻射引發(fā)百姓健康隱憂Could your cellphone give you cancer? Whether it could or not, some people are worrying about the possibility that phones, powerlines and wi-fi could be responsible for a range of illnesses, from rashes to brain tumors。For example, Camilla Rees, 48, a former investment banker in the US, moved out of her apartment in San Francisco because of the radiation coming from next door。Rees told the Los Angeles Times that when her neighbors moved in and installed a wi-fi router she lost her ability to think clearly. “I would wake up dizzy in the morning. Id collapse to the floor. I had to leave to escape that nightmare,” she said. Since then, shes been on a crusade against low-level electromagnetic fields, or EMFs。And shes not alone. Millions of people say they suffer from headaches, depression, nausea and rashes when theyre too close to cellphones or other sources of EMFs。Although the World Health Organization has officially declared that EMFs seem to pose little threat, governments are still concerned. In fact, last April, the European Parliament called for countries to take steps to reduce exposure to EMFs. The city of San Francisco and the state of Maine are currently considering requiring cancer-warning labels on cellphones。If these fears are justified, then perhaps we should all be worried about the amount of time we spend talking on our phones or plugging into wi-fi hotpots。Some say there is evidence to support the growing anxieties. David Carpenter, a professor of environmental health sciences at the University at Albany, in New York, thinks theres a greater than 95 percent chance that power lines can cause childhood leukemia. Also theres a greater than 90 percent chance that cellphones can cause brain tumors。But others believe these concerns are unjustified paranoia. Dr Martha Linet, the head of radiation epidemiology at the US National Cancer Institute, has looked at the same research as Carpenter but has reached a different conclusion. “I dont support warning labels for cellphones,” said Linet. “We dont have the evidence that theres much danger?！盨tudies so far suggest a weak connection between EMFs and illnessso weak that it might not exist at all. A multinational investigation of cellphones and brain cancer, in 13 countries outside the US, has been underway for several years. Its funded in part by the European Union, in part by a cellphone industry group. The final report should come out later this year, but data so far dont suggest a strong link between cellphone use and cancer risk。According to Robert Park, a professor emeritus of physics at the University of Maryland in the US, the magnetic waves arent nearly powerful enough to break apart DNA, which is how known threats, such as UV rays and X-rays, cause cancer。Perhaps its just psychological. Some experts find that the electro-sensitivity syndrome seems to be similar to chemical sensitivity syndrome, which is a condition thats considered to be psychological。Psychological or not, Rees suffers physically and has her own defense strategy. She shuns cellphones and spends as much time as she can in low-EMF areas. “I like to spend time in the mountains and by the sea,” she said。Whether EMFs are harmful or not, a break in the countryside, without the cellphone, would probably be good for all of us。手機(jī)輻射引發(fā)百姓健康隱憂隨著手機(jī)以及Wi-Fi設(shè)備等工具的日益普及，人們逐漸對(duì)這些用具的電磁輻射(electromagnetic radiation)產(chǎn)生恐懼，認(rèn)為他們對(duì)身體產(chǎn)生極大危害，會(huì)導(dǎo)致皮疹，腦瘤等疾病。然而時(shí)至今日，依舊沒有一個(gè)確定的結(jié)論，表明低強(qiáng)度電磁輻射會(huì)對(duì)人體造成損害。手機(jī)可以致癌？不管這一說法是否屬實(shí)，人們已經(jīng)開始擔(dān)心，電話，輸電線以及wi-fi可能會(huì)引發(fā)皮疹，腦瘤等一系列疾病。48歲的美國(guó)人Camilla Rees曾是一名投資銀行專家。由于受不了鄰居家產(chǎn)生的電磁輻射，她搬出了位于舊金山的寓所。 Camilla Rees在接受洛杉磯時(shí)報(bào)采訪時(shí)表示，新鄰居入住后就安裝了Wi-Fi路由器，之后自己便失去了清晰思考的能力。她說：“早晨起床時(shí)我會(huì)覺得頭暈，并且常常會(huì)摔倒在地板上。我必須要逃離這個(gè)夢(mèng)魘?！睆哪菚r(shí)起，Camilla Rees就成為了一位堅(jiān)決反對(duì)低強(qiáng)度電磁輻射(也被稱為EMFs)的人士。 而她并非孤立無援。數(shù)以百萬記的民眾表示，當(dāng)同手機(jī)及其它電磁源親密接觸時(shí)，自己會(huì)感到頭痛、抑郁、惡心，并患上皮疹。盡管世界衛(wèi)生組織已發(fā)表官方聲明稱，電磁輻射似乎不會(huì)造成太大的威脅；但各國(guó)政府還是對(duì)此非常擔(dān)憂。事實(shí)上，去年四月份，歐洲議會(huì)就曾呼吁各國(guó)采取重大措施，控制電磁磁場(chǎng)的影響范圍。同時(shí)，舊金山及緬因州也正在考慮在手機(jī)上粘貼“手機(jī)會(huì)提高癌癥可能性”的標(biāo)簽。如果這些擔(dān)憂并非無稽之談，那么我們可能都要為自己花在電話和wi-fi無線網(wǎng)絡(luò)上的時(shí)間而擔(dān)憂了。人們表示不斷增加的恐慌是有一定依據(jù)的。紐約阿爾巴尼大學(xué)環(huán)境健康科學(xué)教授David Carpenter認(rèn)為，高壓電線導(dǎo)致發(fā)生兒童期白血病的幾率超過95%。同時(shí)，機(jī)會(huì)導(dǎo)致發(fā)生腦部腫瘤的幾率也超過90%。但也有一些人認(rèn)為這是在杞人憂天。美國(guó)國(guó)立癌癥研究所的輻射病學(xué)主任Martha Linet博士也曾做過與Carpenter教授一樣的研究，但得出的結(jié)論卻不同。Linet博士說：“我不贊成在手機(jī)上粘貼警示標(biāo)志，目前我們并沒有證據(jù)表明手機(jī)的使用會(huì)造成腦癌的發(fā)生。” 到目前為止，各項(xiàng)研究數(shù)據(jù)表明電磁輻射同各種疾病之間聯(lián)系甚微，甚至可以忽略不計(jì)。一項(xiàng)由13個(gè)國(guó)家參與，致力于驗(yàn)證手機(jī)是否會(huì)導(dǎo)致腦癌的跨國(guó)研究已進(jìn)行多年。該研究由歐盟及部分手機(jī)產(chǎn)業(yè)公司贊助。該研究報(bào)告將于今年年底公布，但目前的研究數(shù)據(jù)卻表明手機(jī)的使用同腦癌的發(fā)生概率二者之間并沒有較大聯(lián)系。美國(guó)馬里蘭大學(xué)(University of Maryland)的名譽(yù)物理學(xué)教授Robert Park則表示，與紫外線以及X射
