Abstract

Health Safety Guidelines and 5G Wireless Radiation [Health Matters] James C. Lin. Health Safety Guidelines and 5G Wireless Radiation [Health Matters]. IEEE Microwave Magazine. 23(1):10-17. Jan. 2022, doi: 10.1109/MMM.2021.3117307. Abstract The rollout of 5G cellular communication technology is well underway worldwide. The advocates of 5G mobile technology hail it as a faster and more secure technology than its predecessor, 3G and 4G systems. The major enabling infrastructure uses millimeter-wave (mm-wave) and phased-array technology to achieve line-of-sight directivity, high data rates, and low latency. A central vulnerability or security threat is that it may allow spying on users. Nevertheless, this is a system architecture and technology or regulatory issue but not a biological effect or health safety matter. ieeexplore.ieee.org My note: Like several past articles written by James C. Lin in IEEE Microwave Magazine, the abstract is biased so read the paper or the following excerpts. Excerpts Low-band 5G starts at roughly 400 MHz and uses existing or previous 3G or 4G frequencies or newly opened frequencies to operate; the latter, for example, may overlap with the existing 4G band. The 5G rollout began with midband, which includes popular frequencies between 3 and 4 GHz. However, primary 5G technological advances are associated with high-band 5G, which promises performance bandwidth as high as 20 GHz, and multiple-input, multiple-output strategies using 64–256 antennas at short distances and offering performances up to 10 times better than the current 4G networks." "For health safety matters, it is not apparent whether the biological responses to high-band 5G radiations would be akin to earlier generations or low-band 5G radiations, given the distinctive characteristics of mm-wave and its interaction with the complex structure and composition of pertinent, superficial biological cells and tissues such as the cornea of the eye and nerve-rich human skin, the large, protective organ of the body." "The two most widely promulgated RF health safety guidelines or standards have recently published revisions of their respective 1998 and 2005 versions [1], [2]. The updated International Commission on Nonionizing Radiation Protection guidelines and IEEE standards appear to cater to industry wishes; they are strongly linked to thermal effects associated with measurable temperature elevations. Also, the updates seem to have been synchronized to accommodate the 5G rollout." "To date, there has not been a single reported epidemiological study that investigated mm-waves and their potential health effects. Thus, although there are roughly 100 published laboratory investigations of all types, and the reported biological responses are inconsistent in their association between biological effects and mm-wave exposure. Indeed, the types of reported laboratory investigations are small, limited, and diverse, considering the wide, 5G, mm-wave frequency domain. The jury on biological effects or health impacts is still out on 5G mm-waves. Moreover, there is a lack of ongoing, controlled laboratory investigations " "If the entities responsible for safety recommendations believe what appears to be their position concerning experimental results from rats from the NIEHS/NTP that a whole-body temperature rise of 1 °C is carcinogenic, then the safety factors of 50 adopted for the public or 10 for workers would be marginal for their stated purpose and practically meaningless from the perspective of “safety” protection (more so above 6 GHz)." "As shown in Table 1, for mm-waves, the referenced local-tissue-temperature rise in the head, torso, and limbs of humans is 5 °C. This level of temperature rise would bring the tissue temperature from a normal value of 37 °C to a hyperthermic 42 °C. A 42 °C tissue temperature is known to be cytotoxic, with exponential cell-killing capacities. It is used as the basis for clinical cancer therapy in hyperthermia treatment for cancer protocols [14]– [16]. The recently updated safety recommendations provide a reduction factor of 10 for the public’s safety and a reduction factor of two in the case of workers. In this situation, the efficacy of these updated safety recommendations is borderline, and the updated recommendations are meaningless from the perspective of safety protection. In summary, the safety recommendation updates were based primarily on limiting the tissue-heating potentials of RF radiation to elevate body temperatures. There are significant anomalies in the recently updated safety recommendations. Moreover, aside from the aforementioned anomalies, the existing scientific data are too limited—especially at mm-wavelengths—to make a reliable assessment or conclusion with any certainty. Some of the updated safety recommendations are marginal, questionable, and lack scientific justification from the perspective of safety protection."

Main findings

This article discusses 5G (including mm-wave) technology and argues that current RF exposure guideline updates (ICNIRP and IEEE) are strongly linked to thermal effects and may be synchronized to accommodate 5G rollout. It states that there have been no reported epidemiological studies on mm-waves and their potential health effects, and that available laboratory studies are limited and report inconsistent biological responses. The author concludes that scientific data are too limited, especially at mm-wavelengths, to make reliable assessments with certainty and characterizes some updated safety recommendations as marginal or questionable from a safety-protection perspective.
