Most wireless phones and their corresponding base stations operate at a very low power output and in the radiofrequency range of 800 to 2000 Megahertz. Current international guidelines protect against thermal biological effects in terms of the local or whole-body specific absorption rate (SAR). Potential non-thermal bio-effects resulting from the use of wireless phones are not established and laboratory (i.e., in vitro, in vivo) studies have shown conflicting results. Epidemiological studies of potential human health effects are few but are expected to emerge in the near future. Challenges to epidemiological research include difficult exposure assessment, selection of appropriate controls, potential confounding bias, and validation of outcome. Scientists, community advocacy groups, and public health professionals must be equipped to critically analyze the emerging evidence within a benefit/risk assessment framework.
大多数无线电话及其相应的基站以非常低的功率输出运行，且处于800至2000兆赫兹的射频范围内。当前的国际准则依据局部或全身比吸收率（SAR）来防范热生物效应。使用无线电话所产生的潜在非热生物效应尚未得到证实，实验室（即体外、体内）研究结果相互矛盾。关于潜在人类健康影响的流行病学研究较少，但预计在不久的将来会出现。流行病学研究面临的挑战包括暴露评估困难、选择合适的对照、潜在的混杂偏倚以及结果验证。科学家、社区倡导团体和公共卫生专业人员必须具备在效益/风险评估框架内批判性分析新出现证据的能力。
