The fifth-generation wireless (5G) has already started showing its capability to achieve extremely fast data transfer, which makes itself considered to be a promising mobile technology. However, concerns have been raised on adverse health impacts that human users can experience in a 5G system by being exposed to electromagnetic fields (EMFs). This article investigates the human EMF exposure in a 5G system and compares them with those measured in the previous-generation cellular systems. It suggests a minimum separation distance between a transmitter and a human user for keeping the EMF exposure below the safety regulation level, which provides consumers with a general understanding on the safe use of 5G communications.

28 GHz下5G中的人体电磁场暴露

第五代无线（5G）已经开始展示其实现极快数据传输的能力，这使其自身被认为是有前途的移动技术。但是，人们对人类用户暴露于电磁场（EMF）中可能在5G系统中遇到的不利健康影响提出了担忧。本文研究了5G系统中人的EMF暴露，并将其与上一代蜂窝系统中测得的EMF暴露进行了比较。它建议在发射器和用户之间保持最小距离，以使EMF暴露保持在安全法规水平以下，这为消费者提供了有关安全使用5G通信的一般知识。
