手机产生“非电离”辐射，它不像X或伽马射线那样从细胞组织中的分子里分理出电子，从而破坏DNA。但高频能量确实产生热量，而且当频率足够高时能破坏细胞组织。以上结论是上世纪九十年代末，由美国联邦通讯委员会(FCC)与欧洲的国际非电离辐射保护委员会(ICNIRP)提出，为了限制手机辐射吸收率(SAR)（即每个手机用户使用电话时吸收的高频能量多少），前者规定最高不能超过1.6瓦特/千克体重，而后者为2.0瓦特/千克体重。这就给我们留下了一些问题：这些标准到底能不能有效保护人们免受长期辐射？是不是当细胞组织（如外耳、大脑、皮肤和睾丸）中血量不够分散热量时，其本身积累的热量破坏性更大？
The exposure standard has been the subject of Congressional hearings. Consumer groups have warned that children may be more susceptible to radiofrequency heating effects than adults. U.S. Congressman Dennis Kucinich introduced a bill for a federal research program on the effects of cell phone radiation that also calls for a label warning users about potential links between long-term use and cancer.
辐射量标准已经成为议会听证会的议题。消费者被告知，儿童比成人更容易受到高频热效应的影响。美国议员Dennis Kucinich提出一项议案，即设立一个联邦项目，研究手机辐射的影响，并号召以后再手机上标示出“长时间使用手机与癌症有潜在关系”之类的标语，警告消费者。
Last month, San Francisco passed a “Cell Phone Right-to-Know” law that requires manufacturers to post in stores each cell phone’s Specific Absorption Rate. In response, CTIA-The Wireless Association, which represents the wireless communications industry, filed suit July 23 in U.S. District Court in San Francisco to block enforcement of the new law. It cites the U.S. Food and Drug Administration’s (FDA) statement that “the weight of scientific evidence has not linked cell phones with any health problems.”
