The impact of providing people with an objectively measured personal radiofrequency electromagnetic fields (RF-EMF) exposure information on the risk perception of people is not well understood. We conducted an experimental study, among three groups of participants, to investigate the risk perception of people towards RF-EMF from Wi-Fi sources (ISM 2.4 GHz) by providing participants with either basic text, precautionary information, or a summary of their personal RF-EMF exposure measurement levels. Participants provided with personal RF-EMF exposure measurement information were more confident in protecting themselves from RF-EMF exposure, compared to those provided with only basic information. Nonetheless, neither the exposure perception nor the risk perception of people to Wi-Fi related RF-EMF differed by the type of information provided. The measured Wi-Fi signal levels were far below international exposure limits. Furthermore, self-rated levels of personal RF-EMF exposure perception were not associated with objectively measured RF-EMF exposure levels. Providing people with objectively measured information may help them build confidence in protecting themselves from Wi-Fi related RF-EMF exposure.

人们没有很好地理解向人们提供客观测量的个人射频电磁场（RF-EMF）暴露信息对人们的风险感知的影响。我们在三组参与者中进行了一项实验性研究，以通过向参与者提供基本文本，预防信息或他们的个人摘要来调查人们从Wi-Fi来源（ISM 2.4 GHz）对RF-EMF的风险感知RF-EMF暴露测量级别。与仅提供基本信息的参与者相比，提供了个人RF-EMF暴露测量信息的参与者更有信心保护自己免受RF-EMF暴露。尽管如此，人们对Wi-Fi相关的RF-EMF的暴露感知或风险感知在所提供的信息类型方面均没有不同。测得的Wi-Fi信号电平远低于国际暴露极限。此外，个人对RF-EMF暴露感知的自我评价水平与客观测量的RF-EMF暴露水平无关。向人们提供客观测量的信息可能有助于他们建立信心，保护自己免受Wi-Fi相关的RF-EMF暴露。
