The aim of this study is to compare the typical peak ElectroMagnetic (EM) exposures from smart phones during data transmission and voice calls, respectively, in the typical Western-European city of Leuven, Belgium. Since transmission powers towards the outdoor network in an indoor environment are expected to be higher than in an outdoor environment, measurements were executed indoors. The influence of factors like network generation [2G, 3G, and 4G] and choice of mobile operator was also investigated. The most important conclusion of the study is that there is a huge difference between peak exposures generated by the 3 network generations currently active in Leuven. To the average, in many cases the peak exposure for 3G is more than a factor 20 lower than for 2G, and about a factor 5-10 lower than for 4G. These numbers are much higher than expected. There are also systematic differences between peak exposures for data mode and voice mode.
本研究旨在比较在比利时鲁汶这个典型的西欧城市中，智能手机在数据传输和语音通话期间的典型峰值电磁（EM）暴露情况。由于在室内环境中，向室外网络传输的功率预计会高于室外环境，因此在室内进行了测量。还研究了网络代际[2G、3G 和 4G]和移动运营商选择等因素的影响。研究的最重要结论是，目前在鲁汶活跃的 3 代网络产生的峰值暴露量存在巨大差异。平均而言，在许多情况下，3G 的峰值暴露量比 2G 低 20 多倍，比 4G 低 5-10 倍左右。这些数字比预期的高得多。数据模式和语音模式的峰值暴露量也存在系统差异。
