The increasing use of Wi-Fi in schools and other places has given rise to public concern that the radiofrequency (RF) electromagnetic fields from Wi-Fi have the potential to adversely affect children. The current study measured typical and peak RF levels from Wi-Fi and other sources in 23 schools in Australia. All of the RF measurements were much lower than the reference levels recommended by international guidelines for protection against established health effects. The typical and peak RF levels from Wi-Fi in locations occupied by children in the classroom were of the order of 10-4 and 10-2% of the exposure guidelines, respectively. Typical RF levels in the classroom were similar between Wi-Fi and radio but higher than other sources. In the schoolyard typical RF levels were higher for radio, TV and mobile phone base stations compared to Wi-Fi. The results of this study showed that the typical RF exposure of children from Wi-Fi at school is very low and comparable or lower to other sources in the environment.
Wi-Fi在学校和其他场所的使用日益增加，引发了公众对Wi-Fi产生的射频（RF）电磁场可能对儿童产生不利影响的担忧。当前研究测量了澳大利亚23所学校中来自Wi-Fi及其他来源的典型和峰值射频水平。所有射频测量值均远低于国际指南中针对已确定的健康影响所建议的参考水平。在教室中儿童所处位置，来自Wi-Fi的典型和峰值射频水平分别约为暴露指南的10⁻⁴和10⁻²%。教室中Wi-Fi和收音机的典型射频水平相似，但高于其他来源。在校园里，与Wi-Fi相比，收音机、电视和移动电话基站的典型射频水平更高。这项研究结果表明，儿童在学校接触来自Wi-Fi的典型射频水平非常低，与环境中的其他来源相当或更低。
