In Russia, as in many countries, there have been active discussions over the past few years about a promising proposal for optimizing cellular communications. This has culminated in the worldwide implementation of the new 5G technological standard which will guarantee fast transmission of vast amounts of data. For this purpose, millimeter wave (MMW) electromagnetic radiation will be used. The techno-economic advantages are far-reaching and widely reported by the media around the world. However, the degree of risk this type of electromagnetic radiation poses to public health and the environment remains unclear. Scientists and medical professionals have appealed to the United Nations and the European Union regarding the necessity for preliminary medical and biological research before implementing the 5G standard. Unfortunately, these appeals have not been acted upon. A number of countries who question the need for the 5G implementation are pondering the health consequences of the densification of EMF pollution. This book by Yuri. G. Grigoriev, et.al, The 5G Health Risk– An Integrated Radiobiological Assessment, examines the potential health implications of the implementation of the 5G standard within the cellular communication system. In contrast to the already existing 2G, 3G and 4G wireless technologies, which use electromagnetic fields in the radio frequency range, the 5G standard additionally utilizes millimeter waves to incorporate the network connections of the Internet of Things (IoT). In order to ensure the stable delivery of MMWs to cover the entire territory of our planet, Earth satellites are used. The launch of 4,425 satellites has been planned to implement the provision of universal Internet access. There are already 800 satellites in space under this program. As a result, the entire population of the earth will be trapped for life in an electromagnetic grid of millimeter waves and no one will be able to avoid their impact. It should be noted that there are currently several thousand satellites in orbit. This fact is of great concern to astronomers (in the context of light pollution) and also for space agencies regarding the safe service of personnel on space flights in Russia. Space junk (debris) is a major problem as collisions create an ever-increasing number of high velocity projectiles that could threaten global communications. Debris larger than the ix size of a tennis ball is currently being tracked, however, NASA has reported over 500,000 untracked objects. MMWs, unlike the current microwave frequencies used for 4G communication, are easily blocked by objects. In practice, to cover a certain area with a millimeter cell, you will need to increase the number of base stations (BS). For example, if the cell radius is only 20 meters, you will need about 800 base stations per square kilometer, located three to five meters from the consumer. This is in sharp contrast, for example, with 3G and 4G requirements, which use large cells and have ranges from 2 to 15 km or more. Since millimeter waves are absorbed in body tissue at a depth of up to 2 mm, only the skin and sclera (white section) of the eye will be affected by them. The authors therefore correctly believe that when assessing the risk of MMW exposures, it is necessary to take into account the presence of two new critical organs, the skin and the eyes. The skin is a very complex biostructure. It is the largest organ in the body and has a large number of receptors. Skin acts as a “bio-relay” between the external environment and the functional state of the body. Naturally, the introduction of 5G technology in the communications system raises new questions. Firstly, there are the technical requirements for the successful use of this type of communication: a significantly larger number of micro-antenna base stations (i.e., antennas) per unit area with satellite support is needed. Secondly, there is the lack of a consistent methodology for health and safety. Thirdly, thus far, there are only assumptions about the possible biological effects of a lifetime of exposure to MMWs on human populations and ecosystems. There is no long-term data on possible health effects from constant exposure to MMWs on the skin and sclera of the eyes. Targeted research or pre-market testing has not been performed in Russia or other countries prior to implementation of this new technology. There are different perspectives on the assessment of the potential hazards of this new technology. The International Commission on Non-ionizing Radiation Protection (ICNIRP) and the US Federal Communications Commission (FCC) assess risk by considering only the additional absorbed dose of electromagnetic thermal energy, according to the pre-existing radiofrequency (RF) standards. This additional dose is considered insignificant (in terms of energy transfer) and therefore the existing FCC and ICNIRP standards, approved back in 1996, are not being materially revised to include other non-thermal emerging potential health aspects. International standards, despite the criticism of the scientific community and the European Union, have remained x unchanged for more than 20 years. The authors of this book assert that the ICNIRP approach is in error since the radiation loads on new critical organs (the skin and the eyes) are not taken into account. The authors contend that the significance of radiobiological criteria and the degree of risk from the emergence of the new critical organs must be considered; in particular, the load on existing critical organs and systems, with a view to lifetime exposure of the population to electromagnetic fields (EMFs). From this point of view, this book presents an assessment of the total radiobiological danger of planetary electromagnetic radiation exposure to the population. The book offers the reader new ways to reduce the electromagnetic load, taking into consideration 5G exposures on the human population. It is necessary to explain to the public that radiofrequency electromagnetic radiation can be harmful and that their protection is regulated by certain radiation protection standards. Exposure to EMFs that exceeds these standards may negatively affect the health of the mobile (wireless) communications user. In this regard, the public should strictly follow the existing health and safety recommendations. Most people, however, perceive their wireless devices simply as a convenient part of everyday life, for entertainment, or as a toy for children. They use wireless communications without restriction and do not consider limiting their conversation time. The general public needs to be made aware that they are violating radiation protection recommendations and putting themselves and their children at risk. This danger must be clearly and persistently explained through public health messaging and in the media. It is necessary to introduce the concept of “exposure risk awareness”. Strong consumer protection advice is required but the telecommunications industry, as well as governments, are reluctant to give this advice as it will acknowledge that these devices are not risk-free and could also adversely affect their profits. To our knowledge this is the first book on 5G that outlines the potential dangers of 5G technology, both in Russia and overseas. The publication of this book is timely.
