Abstract:
This article discusses the contention in the commented-upon paper that Brillouin precursors generated by 5G New Radio (5G NR) and other cellular systems are a possible cause of tissue damage at deeper layers of tissue than the power penetration depth of the carrier frequency. The original theory for Brillouin precursors from pulsed radiofrequency signals (RF-EMF) and speculation about their possible health effects dates back to the 1990\'s and was based on studies of the propagation of very short (nanosecond) ultrawide-bandwidth RF pulses through water. This assumption is not correct for cellular telephone signals due to their narrow bandwidth. The commented-on paper provides no alternative rationale as to why Brillouin effects should cause tissue damage from RF-EMF radiation from cellular and other communications systems. Other inaccuracies in this paper concerning thermal responses of tissue to RF-EMF are also noted.
摘要:
本文讨论了评论论文中的争论,即5G新无线电(5GNR)和其他蜂窝系统生成的布里渊前体可能是比载波频率的功率穿透深度更深层组织损伤的原因。来自脉冲射频信号(RF-EMF)的布里渊前体的原始理论以及对其可能的健康影响的推测可以追溯到1990年代,并且基于对非常短(纳秒)超宽带宽RF脉冲传播的研究通过水。由于蜂窝电话信号的窄带宽,这种假设对于蜂窝电话信号是不正确的。评论过的论文没有提供替代的基本原理,说明为什么布里渊效应会导致蜂窝和其他通信系统的RF-EMF辐射造成组织损伤。本文还指出了有关组织对RF-EMF的热响应的其他不准确性。
