Recent studies have indicated that acute exposure to low level radiofrequency (RF) electromagnetic fields generated by mobile phones affects human cognition. However, the relatively small samples used, in addition to methodological problems, make the outcomes of these studies difficult to interpret. In our study we tested a large sample of volunteers (168) using a series of cognitive tasks apparently sensitive to RF exposure (a simple reaction task, a vigilance task, and a subtraction task). Participants performed those tasks twice, in two different sessions. In one session they were exposed to RFs, with half of subjects exposed to GSM signals and the other half exposed to CW signals, while in the other session they were exposed to sham signals. No significant effects of RF exposure on performance for either GSM or CW were found, independent of whether the phone was positioned on the left or on the right side.
近期研究表明，急性暴露于手机产生的低水平射频（RF）电磁场会影响人类认知。然而，除了方法学问题外，所使用的样本相对较小，使得这些研究的结果难以解释。在我们的研究中，我们使用了一系列显然对射频暴露敏感的认知任务（一个简单反应任务、一个警觉任务和一个减法任务）对大量志愿者样本（168名）进行了测试。参与者在两个不同的时段将这些任务执行了两次。在一个时段中，他们暴露于射频下，一半受试者暴露于GSM信号，另一半暴露于连续波（CW）信号，而在另一个时段中，他们暴露于伪信号。无论手机是放在左侧还是右侧，均未发现射频暴露对GSM或CW的表现有显著影响。
