Summary

With a growing network of smart devices and phones, the 4G network is getting very crowded. The speeds that it supports are not keeping up with technology demands and with AI controlling more and more, 4G is becoming inadequate. So 5G is being rolled out apace.

The sources of EMF (electromagnetic field) radiation will be: Cell Masts, Satellites and peripheral equipment such as mobile phones, routers and the like. From what we have seen, it is emissions from Cell Masts which cause the greatest concern. But the total EMF exposure, including emissions from new satellites and handsets, cannot be ignored.

Such concerns focus mainly on the risk of heating in human tissue, which depend on:

i)   the power of the electromagnetic field (EMF) in Watts (W) and

ii)  the time for which the tissue is exposed to the EMF.

The heating profile depends on EMF frequency and potential gradients, while power intensity of exposure depends on distance from the cell mast, according to the inverse square law.

As seen in the Appendix, the NHS concludes that there is “no evidence that radio frequency radiation from mobile phones or masts causes unpleasant symptoms.”

Also in Feb 2020 Ofcom conducted measurements around 16 different UK mobile phone base stations – concluding that emission levels were at very small fractions of the safety levels for exposure published by Public Health England. The values measured at 3.4 GHz (5G) were all well below 0.01% ICNIRP levels.

But those who expressed concerns at exposure to EMF (Electromagnetic Fields) from 4G are no less concerned about the potential health impact from 5G.

Indeed, one link reports that “seven clusters of cancer …. have been discovered around mobile phone masts” in the UK – with high incidences of cancer, brain haemorrhages and high blood pressure within a radius of 400 yards of mobile phone masts and that other European countries have seen a “rise in cancers close to masts”.

Yet an ICNIRP link says that “there is a dearth of radio frequency exposure research” and ”that although exposures have occasionally been shown to cause severe harm, the literature lacks concomitant evidence of the lowest exposures required to cause harm.”

Legal limits on emissions must clearly take account of such information, linking the statistics to frequency, power level exposure and its duration. As seen below, 332 “scientists and medical doctors” appealed for a moratorium on the G5 rollout, in absence of such information.

While NHS and Ofcom reports suggest that there should be no cause for concern, more time is needed to allow time to address the above concerns and to reassure the public. At present there is a perception that the 5G rollout is uncontrolled.

So pending the validation of safe limits, it would make sense to regulate the roll out of 5G technology, until the long term health effects have been fully researched and legal limits on emissions have been validated. 

Affect on Human Tissue.

The ICNRP document referred to in the Appendix describes how EMF could raise the temperature of human tissue. As the EMF propagates away from a source (eg from a cell mast) its power impacts upon material, such as human tissue.

Some of the power is reflected away from the body, and some is absorbed by it. This results in complex patterns of electromagnetic fields inside the body that are heavily dependent on the EMF characteristics as well as the physical properties and dimensions of the body.

Electric fields inside the body are referred to as induced electric fields (Eind, measured in volt per meter; V m−1), and they can affect the body in different ways that are potentially relevant to health.

If the induced electric field is below about 10 MHz and strong enough, it can stimulate nerves and can cause dielectric breakdown of biological membranes. The link below provides more information.

New Masts

A report by the EM Radiation Research Trust (EMRT) dated 11th October raises a number of concerns. It cites a report that, starting in October 2019, BT is launching 5G in 9 major cities, including London and Manchester.

EMRT says that this will “dramatically increase the number of radio frequency transmitters, leading to an increase in microwave radio frequency exposures for the public, pollinating insects and other wildlife.”

It does not suggest that intensity of emissions from hand held phones will increase directly as a result of the 5G roll out, but that should be verified. However, it does say that the roll out will “greatly increase radio frequency exposures for the UK public”.

New Satellites

In addition to new masts, there will apparently be 42,000 5G satellites in low and very low orbit in the Earth’s ionosphere. Those are in addition to the existing 12,000 Iridium satellites, which it has been claimed, caused health problems for many people.

It seems that the EMR from each SpaceX satellite will be about one thousand times as powerful as the beams from each existing Iridium satellite. It is claimed that this will interfere with the ionosphere, with a direct effect on public health.

Conclusions

The pace of G5 rollout is driven by commercial considerations, but there are still too many unanswered questions on its impact on health, to allow the programme to accelerate – until the long term impact of health has been fully evaluated.  

Appendix – Weblinks:

i)  New Satellites

As seen in this link, on October 7, 2019, the International Telecommunication Union posted new applications by SpaceX for 30,000 more satellites, in addition to the 12,000 that have already been approved, for a planned total of 42,000 5G satellites in low and very low orbit in the Earth’s ionosphere.

ii) The Appeal for a Moratorium

In 2017 an Appeal by a group of “Scientists” recommended a moratorium on the roll out of 5G until potential hazards for human health …  have been fully investigated.

iii) More New Masts

5G will utilize millimetre waves in the 30-300 gigahertz frequency, which hasn’t been used in the past. These higher frequencies have short wavelengths and are categorically more dangerous. The shorter wavelengths also do not travel as far, or as well through objects. This means that 5G will require hundreds of thousands of small cell towers to compensate: link.

iv) EU Policy

But as seen here Europe seems to have agreed to harmonise frequencies in the 26GHz band as the 5G enabler. But many 5G networks will operate at frequencies close to those currently used.

v)  Rapid Rollout

This link says that the rapid rollout of this technology “without any testing on the long-term health effects is immensely troubling. So it’s natural to be concerned.”

vi)   NHS Advice

Here the NHS concludes from The Mobile Telecommunications and Health Research Programme (MTHR) reports, one in September 2007 and one in February 2014, that there is “no evidence that radiofrequency radiation from mobile phones or masts causes unpleasant symptoms.”

vi) ICNIRP Advice

But this link says that “there is a dearth of radiofrequency exposure research using sufficient power to cause heat-induced health effects. Of particular note is that although exposures (and resultant temperature rises) have occasionally been shown to cause severe harm, the literature lacks concomitant evidence of the lowest exposures required to cause harm.”

vii) Accumulative RF EMF Impact

This link says that 5G will substantially increase exposure to radiofrequency electromagnetic fields (RF-EMF) on top of the 2G, 3G, 4G, Wi-Fi, etc. for telecommunications already in place. RF-EMF has been proven to be harmful for humans and the environment.

vii) Cancer Clusters

This link implies that seven clusters of cancer have been discovered around mobile phone masts. It reports high incidences of cancer, brain haemorrhages and high blood pressure within a radius of 400 yards of mobile phone masts.

viii) Ofcom Measurements

In Feb 2020 Ofcom conducted measurements around 16 different UK mobile phone base stations (link) – concluding that emission levels were at very small fractions of the safety levels for exposure published by Public Health England. They did not measure RMS (Root Mean Square) power density, but average field strength as a % of ICNIRP reference levels for public exposure. They summated the various % measured values without any kind of weighting. Values measured at 3.4 GHz (5G) were all well below 0.01% ICNIRP levels.
