Are cell phones risky?
手机是否对健康有害？
Cell phones are everywhere.There are over six billion cell phone subscriptions worldwide,nearly one for every man,woman and child on the planet.And many people claim they can no longer live without them,but are they safe? Is it possible that something so near and dear to us could be risky and if so what kind of risk would it be? For starters,most cell phones these days use lithium-ion batteries which as a previous risk bites explored can present a fire risk if you abuse them,but so long as you don't treat your phone like a racquetball,you probably OK. Vent this the nonionizing radiation like other wireless electronic appliances.
手机无处不在。全世界有超过60亿手机用户，几乎地球上每一个男女，儿童人手一部。许多人宣称离开手机他们活不下去，但是手机是安全的吗？离我们如此近，对我们来说如此宝贵的东西有没有可能是危险的？如果是的话，会有什么危险？对于刚开始使用手机的人来说，当前大多数手机用的都是锂离子电池。如果粗暴对待手机，可能会引发火灾。但是只要对待你的手机不像墙球一样，你应该就不会有什么危险。对待这些非电离的辐射像对待其他无线电子设备一样就可以了。
Cell phones use high frequency radio waves to do their thing. These radio waves allow the phone to communicate with satellites computers and other phones which in turn allow us to communicate with each other.What makes cellphones different from other wireless appliances is that we have a habit of holding them next to our heads,so it's perhaps not surprising that researchers have asked it has any risk associated with extended exposure to cell phone radiation.
手机使用的是高频电波。这些电波让手机能够与卫星电脑和其他手机联系，从而允许我们互相沟通。让手机与其他无线设备不同的是，我们习惯把手机拿得离头部非常近，这样就毫不奇怪，研究人员质疑过度暴露于手机辐射是否会产生风险。
To put it bluntly they want to know can cell phones give you brain cancer.Researchers in the United States,Sweden,Denmark,Switzerland, UK and other countries have been looking into the question since cellphones first hit the market in the nineteen eighties.For years they have tracked cases a phone usage in brain cancer across time and geography.After decades have resurgent massive studies using hundreds of thousands of people from multiple countries.The answer is a resounding probably not.
直白地说，他们想要知道手机是否会导致脑瘤。美国，瑞典，丹麦，瑞士，英国和其他国家的研究人员自上世纪80年代手机问世就开始研究这个问题。多年来，他们追踪了手机使用不同时间不同地理位置对脑瘤的影响。数十年之后，他们利用来自许多国家数十万人的数据进行了大量研究。答案是应该不会。
In 2011,the World Health Organization pulls together a group of experts from around the world to review the available data on cell phone radio waves and cancers. The conclusion:vast majority of evidence shows no increase risk associated with cell phones,however a slender few reports did find a slight association between cell phone use and cancer.So the WH0 being a cautious body declared cell phone radio wave emissions to be of possible human carcinogen.
2011年，世界卫生组织聚集了世界各地一些专家，对手机电波和癌症已知的数据进行重审。他们得出结论：大量证据表明，使用手机不会导致风险增加。然而，少量报告却发现手机使用和癌症之间有着轻微的联系。所以，作为预警组织，世界卫生组织宣布手机电波辐射为可能的人类致癌物质。
What does this mean? Simply there isn't enough evidence to be sure either way. We can't say that cell phones are unsafe,but we don't know if they are 100 percent entirely safe yet either. That may sound scary but before you cancel your phone subscription,consider that this category possible carcinogens also includes coffee and pickled vegetables.Surprisingly the best studied risk associated with cell phones comes not from the phone itself,but from the distraction it causes to drivers. Will dive into that another time but until then don't forget to subscribe and stay safe and whatever you do don't watch risk bites while driving.
这是什么意思？简单地说，没有足够证据表明有害或无害。我们不能说手机是不安全的，但是也不知道是不是百分之百安全的。这听上去或许很可怕，但是在取消手机之前，考虑下面这一点：可能的致癌物质名单还包括咖啡和腌菜。令人惊讶的是，已经得到研究证实的与手机有关的风险不是来自手机本身，而是来自手机对司机造成的精力分散。你可以继续使用手机，但是不要忘记保持安全，无论你要做什么，都不要在驾车的时候使用手机。
