Complete guide to 5G
Thousands of people protested in the Swiss capital Bern over 5G dangers in September 2019, the Belgian government halted a 5G test in Brussels earlier this year, and members of parliament in the Netherlands have asked the government to examine 5G more closely. In short, concerns about the health implications of 5G are gaining traction.
5G technology - promising high speeds, lower latency, and the activation of the Internet of Things (IoT) - is still hugely controversial. Citizen groups and some scientists argue that radio frequency (RF) energy exposure - particularly the high frequency part of the spectrum used by 5G – is dangerous to people and the environment.
However, many credible scientific bodies, journalists, and technology experts are exasperated by the claims arguing that the science just doesn’t stand up. Can these scientists be right when so many parties are worried, and, if so, how did fears about 5G become so prevalent?
The dangers of 5G
5G networks employ low (0.6 GHz – 3.7 GHz), mid (3.7 – 24 GHz), and high-band frequencies (24 GHz and higher) to deliver their services. Speaking generally, it is the high band frequencies that have caused most concern, although ongoing worries about 2G, 3G and 4G, which use the low and mid part of the range, have not subsided.
Concerns around 5G fall into two categories: first, that millimetre waves (MMW) used by 5G and transmitted via the 30-300 Ghz part of the spectrum, are more likely to cause cellular damage than lower frequency waves. Second, these short waves do not travel far meaning more small cell transmitters are required to provide full coverage - the number of transmitters needed is worrying some groups.
Impact of MMW on cells
One concern about MMWs is that because they lie between microwaves and infrared waves on the RF spectrum, they pose heating dangers. Some argue that this will cause cell breakdown.
And some studies seem to show that MMW exposure may affect cell structure. A blog by Joel Moskowitz, director of the centre for family and community health, University of Berkeley, argues that MMWs can affect the cell’s plasma membrane, either by modifying ion channel activity or by modifying the phospholipid bilayer. He says: “Skin nerve endings are a likely target of MMWs and the possible starting point of numerous biological effects”.
However, many scientists argue that 5G radiation (the RF sort emitted by a 5G infrastructure) simply can’t harm human cells this way. On the American Council for Science and Health site, Alex Berezow quotes astrophysicist Dr. Ethan Siegel when attempting to explain how to determine whether a source of radiation is dangerous. Siegel argues that there are three considerations: the energy per photon, the total amount of energy, and the ability of the exposed object to absorb the radiation. He argues that the photons associated with the radio spectrum are too weak to cause cancer; the total amount of energy to which our bodies are exposed by RF radiation is low; and that our bodies don’t absorb it well anyway.
More broadly, many scientists are sceptical of the quality of research into the harmful impact of 5G. Kenneth R Foster, professor of bioengineering at the University of Pennsylvania is one. In a recent Scientific American blog he said: “many of the studies [around the harmful effects of RF and 5G] are exploratory in nature, and lack elementary precautions to ensure reliable results.”
A more balanced approach towards whether 5G will cause harm is given by bodies such as the US-based National Institute of Environmental Health Sciences (NIEHS). A spokesperson for the group said that they don’t yet know what the impact of exposure to RF will be on biological tissues, and that the range of frequencies utilised by 5G complicates issues further. She added: “We do know that absorption of RF at higher frequencies differs significantly from absorption at lower frequencies in that shorter wavelengths cannot penetrate nearly as deep into the body. This means that much of the higher frequency absorption occurs in the skin and would not penetrate deep enough to reach the heart, brain, or adrenal glands.”
She continued: “At this point, it is unclear exactly whether, or to what degree, human exposure to RF will change with 5G. What is known, however, is that while continuing to be exposed to the current frequencies, wireless consumers will be exposed to the higher frequencies as well.”
In a 2018 review, the Swedish Radiation Safety Authority was similarly circumspect. It argued that although there is no established mechanism for affecting health with weak radio wave exposure there is need for more research covering the novel frequency domains used for 5G.
Critics of 5G often cite a 2011 study by the World Health Organization's International Agency for Research on Cancer which classified RF radiation as "possibly carcinogenic to humans". However, to put this into perspective, the agency also categorised 5G alongside using talcum powder and eating pickled vegetables.
And in a later report in 2014, the World Health Organization explicitly stated that "no adverse health effects" occurred from the use of mobile phones.
5G cancer risk
One way that many scientists attempt to understand the harmful consequences of 5G radiation is by considering its properties. High-energy radiation (including x-rays and gamma rays) has an ionizing impact. This means it has enough energy to remove an electron from an atom or molecule and can damage cell DNA, potentially leading to cancer. However, according to Professor Rodney Croft, adviser to the International Commission on Non-Ionizing Radiation Protection (ICNIRP) there is no 5G cancer risk, as the levels of MMW used for 5G (and earlier mobile technologies) are so low that the heating effects are not harmful.
David Robert Grimes, physicist and cancer researcher argues similarly: “The radio wave band used for mobile phone networks is non-ionising, meaning it lacks sufficient energy to break apart DNA and cause cellular damage."
Small cell transmitters
The second major 5G concern is the density of the small cell infrastructure. Increased proximity to these cells versus 4G transmitters is inevitable since they will be mounted on street signs and in buildings. However, a spokesperson for the US-based National Institute of Environmental Health Sciences explained that RF exposure might actually be lower with 5G. She said: “the proximity of humans to cells may increase, potentially leading to higher exposure but the antennas will be widely dispersed meaning the RF given off by 5G may be lower than that currently transmitted by 2G, 3G, and 4G.”
5G conspiracy theories abound
Conspiracy theories around 5G range from the half plausible to the utterly bizarre and they have grown in popularity in recent years.
One fairly widespread theory, propagated by writers such as Mark Steele in his book, 5G Apocalypse: The Extinction Event, is that the 5G rollout will be used as a weapon to reduce the population. Some members of the alt right argue that there is evidence that Google is involved in the plans to build a nationalised 5G network in a bid to monitor and control the population.
Martin Pall, retired professor of biochemistry and basic medical sciences at Washington State University is one of the most widely quoted critics of 5G and although he is not a conspiracy theorist exactly, his claims are extreme. He argues that 5G will cause an “almost instantaneous crash in human reproduction” as well as insomnia, fatigue, depression, anxiety, major changes in brain structure in animals, cellular DNA damage, oxidative stress, hormonal disruption and cancer. That MMWs transmit at a non-ionising radiation frequency helps counter these claims.
Another vocal critic of 5G is a Dutch UFO researcher John Kuhles, founder of the ‘Stop5G’ Facebook group. Last year the group propagated the idea that the mysterious death of 300 birds in the Netherlands was the result of 5G testing. The claim collapsed when journalists reported that the test had actually taken place months earlier.
Is 5G dangerous?
The volume of research on 5G make it difficult to sort good research from bad and understand whether the technology is harmful or not. It is particularly difficult when social media encourages people to share the most ‘interesting’ and potentially alarming stories.
Although there is little in the science that gives real cause for concern, the frequency domains used by 5G are novel and, as the Swedish Radiation Safety Authority says, require additional research. Either way it is important that the more balanced reports reach ordinary people and help to ease their concerns.
5G dangers: latest news
Petition targets 5G rollout in Devon
Local campaigners in the small Devon town of Totnes have launched a petition claiming that the 5G masts pose a serious health hazard.
Almost 400 Totnes residents have signed the petition for more safety research on 5G, and it’ll be interesting to see what decision the town comes to.
There has never been any solid evidence to either confirm or allay health concerns around 5G, which is exactly why residents are campaigning; they want further research to be carried out before the masts are installed.
And all this, despite the fact that Telecom companies, Public Health England, and the WHO have all said that 5G has no adverse effects on human health.
