如今的世界，手机已经成为人们必不可少的随身用品。人们不仅用它来打电话，通讯联络，而且用它上网查资料，发邮件，上面书，织微博；用它听音乐，看油条；摄影，录像。。。 据统计世界上四分之三的人口，多达 5 billion的人使用手机。人们离不开手机，它也成了人类最亲密接触的朋友。 可是，这样亲密接触的关系，也带来了人们对它安全性的质疑。手机发出的电磁波是否能引发癌症等疾病？ 有研究表明，长时间的把手机放在耳边煲电话粥的人有引发脑瘤的可能性。国际癌症协会也把这电磁波和咖啡，汽车废气一起列入了有致癌可能性的行列（International Agency for Research on Cancer to classify electromagnetic energy from cell phones as "possibly carcinogenic," adding it to a list that includes things such as coffee and gasoline engine exhaust.）。记得旧金山市议会还有过让每个手机厂家在手机上标出手机辐射量的提案。。。 不过，这种长时间把手机放在耳边煲电话粥的人总归是少数。 最近，丹麦对35万人进行了手机使用的相关调查，这个大规模研究表明使不使用手机，在癌症的发病率上并没有根本差别。 研究表明，虽说手机能发出电磁波，但电磁波和医学检查仪器所产生的放射性是不同的, 危害要低的多。 所以，使用手机是安全的。好好享受手机带给你的快乐吧。  不过，如果你是经常要用手机或长期煲电话粥的人，至少要保持你的耳朵和手机有1英寸的距离，用有线耳机或蓝牙也是个不错的主意。

Your device is probably safe. The biggest study ever to examine the possible connection between cell phones and cancer found no evidence of any link, suggesting that billions of people who are rarely more than a few inches from their phones have no special health concerns. The Danish study of more than 350,000 people concluded there was no difference in cancer rates between people who had used a cell phone for about a decade and those who did not. Last year, a separate large study found no clear connection between cell phones and cancer. But it showed a hint of a possible association between very heavy phone use and glioma, a rare but often deadly form of brain tumor. However, the numbers of heavy users was not sufficient to make the case. That study of more than 14,000 people in multiple countries, in addition to animal experiments, led the International Agency for Research on Cancer to classify electromagnetic energy from cell phones as "possibly carcinogenic," adding it to a list that includes things such as coffee and gasoline engine exhaust. But that designation does not mean the phones necessarily pose a risk. Cell phones do not emit the same kind of radiation as that used in some medical tests or found in other sources such as radon in soil. Two U.S. agencies - the Food and Drug Administration and the Federal Communications Commission - have found no evidence that cell phones are linked to cancer. Yet fears of a link persist, despite the fact that cancer rates have not risen since cell phones were introduced. About three-quarters of the world's population, more than 5 billion people, use a cell phone. This article appeared on page A - 12 of the San Francisco Chronicle
