無線藍牙耳機或增加患癌機率?

The internet is abuzz today with worries about the latest tech-fad-turned-health-hazard, with headlines warning that wireless headphones-like Apple's trendy AirPods-are a potential source of cancer. And yes, articles claiming that the little white devices could "pump radiation into your brain" caught our attention. But before we freak out too much, let's look at all the facts.

現而今，網上都在擔心最新的技術時尚變成健康危害，頭條新聞警告稱：無線耳機--比如蘋果公司旗下的潮流AirPods--是癌症的潛在來源。是的，各種聲稱這種精小的白色設備或"造成大腦輻射"的文章引起了我們的注意。但在我們過度驚慌之前，先了解了解現實吧。

Those headlines you may be seeing today seem to stem from a Medium article published last week, which posed the question, "Are AirPods and Other Bluetooth Headphones Safe?" The article quotes Jerry Phillips, PhD, a professor of biochemistry at the University of Colorado at Colorado Springs, who says he's concerned about AirPods because "their placement in the ear canal exposes tissues in the head to relatively high levels of radio-frequency radiation."

你所看到的這些頭條新聞似乎都源於Medium期刊上週發表的一篇文章，提出了這樣一個問題，"AirPods和其它的藍牙耳機安全嗎？"該篇文章引用了科羅拉多斯普林斯市科羅拉多大學生物化學系教授傑瑞·菲利普斯（Jerry Phillips）博士的一段話，菲利普斯表示他很擔心AirPods耳機，因爲"將藍牙耳機置於耳道中會使大腦組織暴露於相對較高水平的射頻輻射。"

The article also points out that Phillips is "not alone" in his concerns about wireless Bluetooth devices, citing a petitionthis addressed to the United Nations and the World Health Organization and signed by 250 researchers from more than 40 countries.

文章還指出，擔心無線藍牙設備存在危害的不止菲利普斯一人，並引用了一則寫給聯合國和世界衛生組織的請願書（來自40多個國家的250名研究員在請願書上籤了字）。

But here's something that's getting lost in the news reports this week: That petition doesn't mention AirPods by name, or even wireless headphones. Rather, the letter expresses "serious concern" about the potential health risks of non-ionizing electromagnetic field (EMF) technology, which is used by all Bluetooth devices.

但本週的報道卻遺漏了這些信息：這則請願書並沒有提到AirPods，甚至都沒有提到無線耳機。相反，該請願書"重點擔心的"是所有藍牙設備使用的非電離電磁場（EMF）技術存在的潛在健康風險。

The petition's not new, either. It was first published in 2015 and last updated on January 1 of this year. Among the devices it calls out by name are "cellular and cordless phones and their base stations, Wi-Fi, broadcast antennas, smart meters, and baby monitors."

這一請願書也不是最近纔出來的，其於2015年首次發佈，並於今年1月1日更新。請願書中提及的設備名稱爲"蜂窩和無繩電話及其基站、無線網、廣播天線、智能電錶和嬰兒監視器。"

Ken Foster, PhD, a professor of bioengineering at the University of Pennsylvania whose research involves the safety of electromagnetic fields, says he's not buying the latest hype about earbuds. "What's the news here? Someone's trying to play the media by resurrecting this petition," he tells Health.

賓夕法尼亞大學的生物工程學教授肯·佛斯特（Ken Foster）博士的研究涉及電磁場的安全性，他表示不相信近來有關耳機的傳聞。"這有什麼值得關注的？有些人試圖重新利用這份請願來戲弄媒體，"他對《健康》雜誌說道。

Yes, it's true that wireless Bluetooth headphones emit radiation. It's also true that Apple sold an estimated 28 million pairs of its iconic AirPods last year-and that there's not a ton of long-term research on the safety of this type of radiation.

是的，無線藍牙耳機的確會發射輻射。但蘋果公司去年售賣大約280萬份標誌性AirPods耳機也是真的--而且關於這種輻射安全性的長期研究並不多。
