Expert urges to stop 5G networks until people’s safety is confirmed

Emily Henderson, News-Medical.net, Jan 19, 2021
We should err on the side of caution and stop the global roll out of 5G (fifth generation) telecoms networks until we are certain this technology is completely safe, urges an expert in an opinion piece published online in the Journal of Epidemiology & Community Health.

There are no health concerns about 5G and COVID-19, despite what conspiracy theorists have suggested.

But the transmitter density required for 5G means that more people will be exposed to radio frequency electromagnetic fields (RF-EMFs), and at levels that emerging evidence suggests, are potentially harmful to health, argues Professor John William Frank, Usher Institute, University of Edinburgh.

The advent of 5G technology has been hailed by governments and certain vested interests as transformative, promising clear economic and lifestyle benefits, through massively boosting wireless and mobile connectivity at home, work, school and in the community, he says.

But it has become the subject of fierce controversy, fueled by four key areas of scientific uncertainty and concern.

The lack of clarity about precisely what technology is included in 5G; and a growing but far from comprehensive body of laboratory research indicating the biologically disruptive potential of RF-EMFs

An almost total lack (as yet) of high quality epidemiological studies of the impact on human health from 5G EMF exposure

Mounting epidemiological evidence of such effects from previous generations of RF-EMF exposure at lower levels

Persistent allegations that some national telecoms regulatory authorities haven’t based their RF-EMF safety policies on the latest science, amid potential conflicts of interest

5G uses much higher frequency (3 to 300GHz) radio waves than in the past and it makes use of very new—and relatively unevaluated, in terms of safety—supportive technology to enable this higher data transmission capacity, points out Professor Frank.

Its inherent fragility means that transmission boosting ’cell’ antennae are generally required every 100-300 m—which is far more spatially dense than the transmission masts required for older 2G, 3G and 4G technology, using lower frequency waves, he says.

A dense transmission network is also required to achieve the ’everywhere/anytime’ connectivity promised by 5G developers.

Existing 4G systems can service up to 4000 radio frequency-using devices per square kilometer; 5G systems will connect up to one million devices per square kilometer—greatly increasing the speed of data transfer (by a factor of 10) and the volume of data transmitted (by a factor of 1000), he explains.

While several major reviews of the existing evidence on the potential health harms of 5G have been published over the past decade, these have been of "varying scientific quality," suggests Professor Frank.

And they have not stopped the clamor from "a growing number of engineers, scientists, and doctors internationally...calling on governments to raise their safety standards for RF-EMFs, commission more and better research, and hold off on further increases in public exposure, pending clearer evidence of safety," he writes.

Permitted maximum safety limits for RF-EMF exposure vary considerably around the world, he points out.

What’s more, ’5G systems’ is not a consistently defined term, comprising quite different specific technologies and components.

It is highly likely that each of these many forms of transmission causes somewhat different biological effects—making sound, comprehensive and up-to-date research on those effects virtually impossible."

John William Frank, Professor, Usher Institute, University of Edinburgh

Recent reviews of lab data on RF-EMFs indicate that exposures can produce wide-ranging effects, including reproductive, fetal, oncological, neuropsychiatric, skin, eye and immunological. But there is absolutely no evidence whatsoever to suggest that it is implicated in the spread of COVID-19, as some conspiracy theorists have suggested, he emphasizes.

"There are knowledgeable commentators’ reports on the web debunking this theory, and no respectable scientist or publication has backed it," he says, adding: "the theory that 5G and related EMFs have contributed to the pandemic is baseless."

But for the current 5G roll-out, there’s a sound basis for invoking ’the precautionary principle’ because of significant doubts about the safety of a new and potentially widespread human exposure, which should be reason enough "to call a moratorium on that exposure, pending adequate scientific investigation of its suspected adverse health effects," he says.

There is no compelling public health or safety rationale for the rapid deployment of 5G, he insists. The main gains being promised are either economic, and then possibly for some more than for others, or related to increased consumer convenience, he suggests.

"Until we know more about what we are getting into, from a health and ecological point of view, those putative gains need to wait," he concludes.

Electromagnetic fields, 5G and health: what about the precautionary principle?

John William Frank. Electromagnetic fields, 5G and health: what about the precautionary principle? J Epidemiol Community Health. Published Online First: 19 January 2021. doi: 10.1136/jech-2019-213595.

Abstract
New fifth generation (5G) telecommunications systems, now being rolled out globally, have become the subject of a fierce controversy. Some health protection agencies and their scientific advisory committees have concluded that there is no conclusive scientific evidence of harm. Several recent reviews by independent scientists, however, suggest that there is significant uncertainty on this question, with rapidly emerging evidence of potentially harmful biological effects from radio frequency electromagnetic field (RF-EMF) exposures, at the levels 5G roll-out will entail. This essay identifies four relevant sources of scientific uncertainty and concern: (1) lack of clarity about precisely what technology is included in 5G; (2) a rapidly accumulating body of laboratory studies documenting disruptive in vitro and in vivo effects of RF-EMFs—but one with many gaps in it; (3) an almost total lack (as yet) of high-quality epidemiological studies of adverse human health effects from 5G EMF exposure specifically, but rapidly emerging epidemiological evidence of such effects from past generations of RF-EMF exposure; (4) persistent allegations that some national telecommunications regulatory authorities do not base their RF-EMF safety policies on the latest science, related to unmanaged conflicts of interest. The author, an experienced epidemiologist, concludes that one cannot dismiss the growing health concerns about RF-EMFs, especially in an era when higher population levels of exposure are occurring widely, due to the spatially dense transmitters which 5G systems require. Based on the precautionary principle, the author echoes the calls of others for a moratorium on the further roll-out of 5G systems globally, pending more conclusive research on their safety.

Background
Fifth generation (5G) technology is being widely promoted by politicians, government officials, and private sector interests. 1–3 They contend that its advent will bring clear economic and lifestyle benefits, through massive increases in wireless and mobile connectivity at home, work, school and in the community. Examples of these 5G benefits include driverless vehicles and ‘The Internet of Things’—automated and continuous communication between the machines in our daily lives. 4 5 On the other hand, the public health response to this wave of communications innovation has become a sense of deep concern, related to widespread scientific uncertainties, as well as a lack of use of existing evidence, in the current international safety guidelines for 5G and related radio frequency electromagnetic field (RF-EMF) exposures.5–8 This commentary sets out the reasons for such concern.

What is 5G and why is it different from past EMF exposures?

Developed over just the last decade, radio frequency (wireless) transmission systems in the 5G category are being rolled out throughout the world. These systems will massively increase the volume, speed and spatial reach of digital data transfer. 4–6 The four successive previous generations (1G, 2G, 3G and 4G) of wireless transmission systems were deployed initially for wireless and mobile phones (1980s and 1990s), followed by WiFi (2000s), and then smart metres and the Internet of Things (2010s). Each successive generation of transmission systems has used higher frequencies of electromagnetic waves to carry ever-larger volumes of data, faster, in more ubiquitous locations. 5G is widely acknowledged to be a step change in this sequence, since it additionally uses much higher frequency (3 to 300 GHz) radio waves than in the past. 5G will also make use of very new—and thus relatively unevaluated, in terms of safety—supportive technology (including pulsing, beaming, phased arrays and massive input/massive output (MIMO)—see below) to enable this higher data transmission capacity. 4–6

However—unlike prior generations of wireless transmission systems—5G ultrahigh-frequency waves are easily interrupted by vegetation foliage (and building walls, often requiring additional signal boosting within each building). This inherent fragility of 5G high-frequency waves means that transmission boosting ‘cell’ antennae are generally required every 100–300 m or less—far more spatially dense than the miles-apart transmission masts required for older 2G, 3G and 4G technology using lower frequency waves. 4–6

This dense transmission network is also required in order to achieve the ‘everywhere/anytime’ connectivity promised by 5G developers, and necessitated by new technology such as driverless cars, which must never be out of internet contact, for safety reasons. Critics of 5G agree 6–8—but its supporters do note 9 10—that the overall population levels of exposure to RF-EMFs will be greatly increased by the 5G roll-out. One compelling argument for that view is the ‘inverse square law’ of EMF exposure: intensity varies as the inverse of the square of the distance from the emitting source. 11 With plans afoot internationally to put a 5G booster antenna on ‘every second or third lamp-post’, it is difficult to believe that overall population exposures will not increase substantially. Existing 4G systems can service up to 4000 radio frequency using devices per square kilometre; 5G systems will connect up to one million devices per square kilometre—greatly increasing the speed of data transfer (by a factor of 10) and the volume of data transmitted (by a factor of 1000). 6
The current controversy

International health protection agencies and their scientific advisory bodies have published several reviews over the last decade, of varying scientific quality, of the research evidence regarding potential adverse biological and health effects of RF-EMFs. 5 12–15 These reviews—by Health Protection England, 12 the International Agency for Research on Cancer (IARC),13 an Expert European Union (EU) Committee 14 and the International Commission on Non-Ionising Radiation Protection (ICNIRP) 15—have, with one exception, not converged around a strong warning about such effects. IARC is the outlier in this respect, having determined in 2011 that EMFs are ‘possibly carcinogenic to humans’. 13 Meanwhile, independent radiation and health scientists have published serious concerns about the current roll-out of 5G transmission systems. 6–8 16–18 Their reasoning is twofold: (1) these systems have an unprecedented potential to create human and non-human RF-EMF exposures orders of magnitude more intense (eg, in terms of ‘power flux density’) than was the case only a few decades ago (16); (2) there is a remarkable dearth of evidence on the safety of 5G-specific EMF emissions, but a growing body of research suggestive of harms from other RF-EMF exposures, which have been studied for much longer. 6–8 17 18

Moreover, a growing number of engineers, scientists, and doctors internationally have been calling on governments to raise their safety standards for RF-EMFs, commission more and better research, and hold off on further increases in public exposure, pending clearer evidence of safety.18–21 Some politicians have listened: France, Israel, Cyprus and Russia have banned WiFi in preschool and restricted its use in primary schools. Belgium has banned the sale of mobile phones to children under seven. In response to such concerns, several jurisdictions have recently blocked the installation of 5G antennae systems in their communities: Brussels, Florence, Rome, as well as Glastonbury, Frome and Totnes in the UK; and widespread anti-5G campaigns are now emerging in Australia, North America and elsewhere. 21

Some countries have lowered allowable RF-EMF exposure levels far below those permitted in the UK and USA. Powerwatch, a non-profit, independent organisation in the UK, has published comparisons of international recommendations on permitted maximum exposure levels to EMFs.22 Those comparisons show that the highest permitted RF-EMF exposures which are used globally, as the basis for national safety guidelines, are those used in the USA, the UK and most of the EU. These exposure limits are derived from the recommendations to WHO in 1998 (recently updated, but essentially not changed, in March 2020) by the ICNIRP.15 These international comparisons show that the safety limit for RF-EMF exposure set by ICNIRP is 10-fold higher than that set by the next most liberal guidelines, found in Israel and India, and 100-or-more-fold higher than the limits set by other guidelines, spanning 14 EU jurisdictions as well as China. As discussed in detail below, one reason that ICNIRP’s permitted exposures are so high is that they are based solely on the acute thermogenic (heat-producing) effects of RF-EMF in animal tissues; this is unlike more conservative jurisdictions’ guidelines, which are based on a wider variety of biological and health effects documented in recent decades, including effects resulting from chronic rather than acute exposures, and effects not mediated by thermogenesis Key contentious issues and scientific uncertainties

Lack of clarity about precisely what sorts of EMFs will result from 5G roll-out
A striking feature of this public controversy is that various commentators—even those with advanced training in telecommunications physics and engineering—inconsistently refer to quite different specific technologies when they discuss the pros and cons of ‘5G’. American authors tend to state that the 5G system roll outs already underway in that part of the world are using very high-frequency (24–100 GHz)/short-wavelength RF transmission—so-called ‘millimetre range’ waves. 6 However, some UK/EU industry websites9 state that ‘no new frequencies are required’ (at present) beyond those already in use in existing 4G mobile networks, WiFi, smart metres. However, independent authors commenting on current private sector plans in the EU, to extend 5G networks more widely in the future, tell a different story. 23 24 These commentaries imply that the use of millimetre wave frequencies—about which we have very few conclusive studies of human health effects—is already planned and inevitable in the EU, and eventually globally, in order to accommodate anticipated consumer requirements—especially the ‘Internet of Things’ and driverless vehicles. Tellingly, the Guardian (one of the UK’s most respected newspapers) reported last year 25 that UK lamp posts were becoming the subject of expensive legal battles, over ‘who can charge what’ for mounting 5G booster cell antennae on them. Cash-strapped Local Councils had hoped to profit from such charges to telecom companies. These companies have taken local governments to court to block those charges. The USA provides a cautionary tale in this respect: nearly 25 years ago national legislation there took local authorities completely out of the telecommunications regulatory system, leaving local 5G installation and similar decisions entirely in the hands of central authorities—that is, the Federal Communications Commission .6
Equally inconsistently described in writings about 5G is the complex set of special signal modulations, pulses, polarisation, phased arrays and novel equipment designs—for example, ‘massive MIMO antennas’—which represent the cutting edge technologies that accompany 5G system installation—many of them proprietary. As some commentators on potential health effects from such exposures have pointed out, it is highly likely that each of these many forms of transmission causes somewhat different biological effects—making sound, comprehensive and up-to-date research on those effects virtually impossible. 5–7 26 27

In short, ‘5G systems’ is not a consistently defined term. This confusion has not helped clarify the health and safety issues surrounding 5G roll outs internationally.

An emerging preponderance of laboratory studies indicating RF-EMFs’ disruptive biological effects: with many knowledge gaps
The lack of a consistent definition of ‘5G’ matters enormously. This is clearly demonstrated in a sophisticated recent review of the laboratory science evidence of RF-EMF effects in diverse biological systems.26 That review shows that the existing scientific literature on the biological effects of more recently developed technology is quite limited, in that there is hardly any study replication—the hallmark of reliable research. We often have only one extant study of any given biological effect of a specified combination of radio frequencies, modulation and pulse patterns. The literature that does exist identifies remarkably heterogeneous biological effects, across hundreds of such specific RF-EMF exposure patterns. Furthermore, a comprehensive Canadian review of the same evidence states that some of the new RF-EMF technologies—such as innovations in radio frequency ‘pulsing,’ ‘polarisation’ and ‘modulation’—are so new that biological scientists have not been able to keep up—that is, no studies yet exist of these new technologies’ biological effects.27

These recent reviews of laboratory (ie, non-epidemiological) studies of the biological effects of RF-EMFs do identify diverse, multibody system effects, operating by a range of physicochemical pathways which are not mediated by thermogenesis. 6 8 26 27The reviewers document a growing body of evidence that RF-EMF exposures produce effects spanning reproductive/teratogenic, oncological, neuropsychiatric, skin, eye and immunological body systems. In addition, there are many fundamental effects at the subcellular level, in terms of oxidation, DNA alteration, gene expression and bacterial antibiotic resistance. Particularly striking is a 2018 study from Israel documenting the capacity of the sweat ducts in human skin to act as ‘helical antennae’ receptive to 5G frequencies of RF-EMF. When sweat ducts are exposed to these RF-EMFs, there are remote systemic effects, through the skin’s established capacity to secrete and send hormones and other signals to the entire body. 28 This report alters one’s sense of the potential risks from such high frequency waves, since they have long been thought to be ‘inherently less dangerous’, because they are largely absorbed in the top few millimetres of exposed tissue (thus limiting any adverse effects, in theory, to the skin or eye).

Finally, it is instructive to look at the two widely cited NIH toxicological studies of specific EMFs’ effects on thousands of rodents, 29 30 conducted by experienced and highly respected laboratory scientists at a world-leading institution. Since their publication in 2018, epidemiologists and other scientists have pointed out several methodological weaknesses in the conduct and analysis of these studies that make their unequivocal interpretation almost impossible, particularly in terms of their relevance to human health: excessive statistical inference testing of multiple (over 1000) hypotheses, without appropriate adjustment of p values considered ‘statistically significant’; reporting of results ‘often ignoring statistical tests’; failure to explain major internal inconsistencies of findings across EMF doses, tumour types and rodent sexes; use of experimental EMF exposures far in excess of any known human ones; uncontrolled confounding by direct thermogenesis effects—the list goes on. 31 32

In short, laboratory studies of EMF exposure are fraught with both internal and external validity issues, and cannot replace high-quality human epidemiological studies—though, as we will now discuss, these are also hard to come by.

Lack of conclusive human epidemiological studies of 5G-specific health effects (but increasing epidemiological evidence of serious health effects from previous generations of RF-EMF exposures)
Canada’s most senior cancer epidemiologist, Miller et al have last year summarised the human epidemiological evidence 33 linking human breast and brain tumours, male reproductive outcomes and child neurodevelopmental conditions to RF-EMF exposures resulting from the use of past generations of transmission systems. Critically, this evidence is not about exposure to the high radio frequency/short wavelength 5G systems. These systems are too newly deployed to have been extensively studied, especially by the highest-quality epidemiological study designs for establishing evidence of causation: prospective cohort studies. Such studies typically require decades of follow-up to detect delayed health effects, such as most cancers.

Miller et al find compelling evidence of carcinogenesis, especially in the brain and acoustic nerve, as well as the breast, from strong RF-EMF exposures to previous generations of mobile phone transmissions. Perhaps the most convincing evidence they cite comes from the oldest and most-often-maligned study design—case reports. While admittedly old-fashioned, case reports can, when they involve pathognomonic effects (ie, pathological features absolutely specific to a particular exposure) provide useful evidence of exposure/outcome specificity—a valuable but often unobtainable epidemiological criterion for inferring causation, according to the standard epidemiological criteria first enunciated by Sir Austin Bradford Hill over 50 years ago. 34 35 Strikingly localised breast tumours, of unusual morphology, have been diagnosed in several women with particularly strong exposures to previous generations of mobile phones: they habitually placed their phones in their bras, on the same side of the body where the tumour has developed. Miller et al call for an urgent update of the last (2011) review of EMFs and cancer by the International Agency for Research on Cancer. 13 They predict that such an update would now rate RF-EMFs as, at minimum, ‘probable’ (not merely ‘possible’ as in 2011) carcinogens, based on current evidence.

Persistent allegations of unscientific bases for existing health protection guidelines on RF-EMFs and unmanaged conflicts of interest on expert advisory panels
A senior epidemiologist from Sweden, Hardell, has repeatedly published in peer-reviewed journals detailed allegations regarding the main WHO scientific advisory body on EMF health effects and safety—the previously mentioned ICNIRP. Hardell contends that ICNIRP’s membership includes over-representation of vested interests, especially the giant multinational telecommunications firms who are heavily invested in the roll out of 5G systems internationally.36 37 ICNIRP has long been influential in EMF regulation: its scientific recommendations to WHO were first issued in 1998, updated in 2009, and revised and updated again in March 2020.15 Hardell points out that ICNIRP’s pro-industry bias may explain its continued reliance only on studies of the thermogenic (heat-producing) effect of RF-EMFs in biological tissues: these studies would be expected to paint an overly benign picture of RF-EMF safety. This narrow ICNIRP focus flies in the face of published reviews by independent scientists (6, 8, 13, 26, 27) citing compelling research evidence, accumulating steadily over the last few decades, of non-thermogenic adverse effects of RF-EMFs, affecting diverse human and animal subcellular function, tissues and organ systems (see above). In detailed, almost lawyer-like publications,36 37 Hardell fastidiously documents the ICNIRP’s 20 years of dogged defiance, in the face of widespread criticism by other scientists, that the scientific base for their recommendations remains dated and narrow, rendering their guidelines on ‘safe’ RF-EMF exposure unsafe.

The most damning evidence adduced by Hardell is a table of the cross-appointments held by six members of the WHO Monograph Group, across five major international advisory panels on the health effects of non-ionising radiation [36 – page 408]. Hardell also describes these scientists’ strong personal links to the telecommunications industry, a situation likely arising from the fact that the ICNIRP itself is a ‘private organisation (non-governmental organisation; NGO) based in Germany. New expert members can only be elected by members of ICNIRP.’ Hardell contrasts the ICNIRP’s reports to the publications of the ‘BioInitiative 2012’38 group, of nearly 30 international experts in this field, whose operations are not only wholly independent of any such ‘vested interests,’ but also entirely transparent. The current version (March 2020) of the BioInitiative 2012 website38 provides detailed descriptions of 988 peer-reviewed scientific studies of adverse potential health and biological effects of EMFs arising from RF and similar non-ionising sources. The vast majority (84.6%) of these 988 studies document disruptive biological effects from such EMFs, almost all of them operating via non-thermogenic pathways. (This writer would have preferred to see more ‘critical appraisal’ of the quality of the studies than the BioInitiative 2012 website provides. However, the major effort entailed in assembling this massive body of scientific evidence, and updating it regularly since 2012, is impressive).

Finally, Carpenter has recently published a well-researched analysis of how source of funding correlates with study findings, across many peer-reviewed publications over the last few decades, of the relationship between various kinds of EMF exposure and several cancers. 39 He shows convincingly that studies funded by private sector entities, with strong vested interests in maintaining their current use of the sources of EMFs under study, tend to find no association—whereas studies funded by public sector or independent sources find the opposite. As Carpenter points out, this suggests that many systematic reviews and meta-analyses in this field, having failed to correct for this ‘source of funding bias,’ likely underestimated the evidence for causation.

Conclusions and recommendation

In assessing causal evidence in environmental epidemiology, Bradford Hill himself pointed out that ‘the whole picture matters;’ he argued against prioritising any subset of his famous nine criteria for causation. One’s overall assessment of the likelihood that an exposure causes a health condition should take into account a wide variety of evidence, including ‘biological plausibility’.34 35 After reviewing the evidence cited above, the writer, an experienced physician-epidemiologist, is convinced that RF-EMFs may well have serious human health effects. While there is also increasing scientific evidence for RF-EMF effects of ecological concern in other species, 6–8 16–18 23 both plant and animal, these have not been reviewed here, for reasons of space and the author’s disciplinary limitations. In addition, there is convincing evidence, cited above, that several nations’ regulatory apparatus, for telecommunications innovations such as the 5G roll-out, is not fit for purpose. Indeed, significant elements in that apparatus appear to have been captured by vested interests. Every society’s public health—and especially the health of those most likely to be susceptible to the hazard in question (in the case of EMFs, children and pregnant women)—needs to be protected by evidence-based regulations, free from significant bias.

Finally, this commentary would be remiss if it did not mention a widely circulating conspiracy theory, suggesting that 5G and related EMF exposures somehow contributed to the creation or spread of the current COVID-19 pandemic. There are knowledgeable commentators’ reports on the web debunking this theory, and no respectable scientist or publication has backed it.40 41 Indeed, combatting it is widely viewed by the scientific community as critical to dealing with the pandemic, as conspiracy theorists holding this view have already carried out violent attacks on mobile phone transmission facilities and other symbolic targets, distracting the public and authorities at a time when pandemic control actions are paramount.42 This writer completely supports that view of the broader scientific community: the theory that 5G and related EMFs have contributed to the pandemic is baseless.

It follows that, for the current 5G roll-out, there is a sound basis for invoking ‘the precautionary principle’.43 This is the environmental and occupation health principle by which significant doubt about the safety of a new and potentially widespread human exposure should be a reason to call a moratorium on that exposure, pending adequate scientific investigation of its suspected adverse health effects. In short, one should ‘err on the side of caution’. In the case of 5G transmission systems, there is no compelling public health or safety rationale for their rapid deployment. The main gains being promised are either economic (for some parties only, not necessarily with widely distributed financial benefits across the population) or related to increased consumer convenience. Until we know more about what we are getting into, from a health and ecological point of view, those putative gains need to wait.
