MOBILES, MASTS AND HEALTH

No. We are always looking to make the most efficient use of masts and infrastructure, so wherever possible we look to upgrade existing sites with new antennas first.

With the addition of 5G transmitters, the total exposure to radio waves will remain very low relative to the international exposure limits. There may be a small localised increase when 5G is added to an existing site or when coverage is provided in a new area, however, all mobile technologies, including 5G, are designed to minimise power and with it exposure to radio waves.

New 5G masts are subject to the same planning requirements and permissions as current masts.

No, they are approximately the same size as existing antennas, although some of them look slightly different. Where possible, we will add 5G antennas to existing 3G /4G sites or in some case may replace existing 3G or 4G antennas. In a small number of cases, the mast itself may need to be upgraded.

Millimeter wave (mmWave) frequencies are typically in the 24-86 GHz range, and today are used for satellite and point-to-point radio links. They can also be used for providing very fast links as part of the network deployments in specific locations such as busy urban areas, stadiums and airports.

At these frequencies, radiofrequency energy is absorbed superficially by the body, mostly by the skin. The biological effects of these frequencies have been the subject of several studies and more are underway using millimetre wave exposures.

The international guidelines extend to 300 GHz and in a recent statement the European Commission said ‘The strict and safe exposure limits for electromagnetic fields recommended at EU level apply for all frequency bands currently envisaged for 5G’.

The word radiation is sometimes associated with illness and cancer, but the emissions from mobile phone technology, including 5G frequencies, are not strong enough to do any damage to humans.

Mobile phones transmit signals using a frequency range that is ‘non-ionising’ – at the low end of the electromagnetic spectrum and carrying less energy. At its worst, non-ionising radiation can cause cells to vibrate - which can be experienced as heat. It doesn’t change the structure of cells or cause lasting damage, unlike exposure to ‘ionising’ radiation including ultraviolet light, X-rays and gamma rays.

In any event, mobile operators fully comply with the ICNIRP guidelines or national equivalents to ensure there is no adverse impact on the health of those using mobile phones or living in communities where base stations or masts are located. Measurements have shown that the total exposure from mobile phones or antennas is significantly below the limits set by ICNIRP and accordingly represents no harm to human health.

Some articles have been written about 5G needing much higher radio frequencies and requiring many more masts than current 4G technology.

These articles are referring to millimetre wave (mmWave) technology, which uses frequencies between 24 - 60 GHz. None of Vodafone’s current 5G services use mmWave and we are unlikely to ever use it widely. When we or other operators deploy it, we would still have to ensure that we complied with the international guidelines set by the ICNIRP.

Because the frequencies used for 5G are close to current 4G frequencies, in almost every case mobile operators can upgrade or replace the antennas and use existing masts for both services.

Many national governments have produced regulations in line with the ICNIRP guidelines and introduced regular monitoring. In some countries, such as India, stricter regulations than the ICNIRP guidelines have been implemented, in response to public pressure. We comply with all national regulations, and where there are no regulations we comply with international science-based guidelines from ICNIRP.

European Commission (2019)

“The strict and safe exposure limits for electromagnetic fields recommended at EU level apply for all frequency bands currently envisaged for 5G” (European Commission, 2019)

United Kingdom: Public Health England (October 2019)

“It is possible that there may be a small increase in overall exposure to radio waves when 5G is added to an existing network or in a new area. However, the overall exposure is expected to remain low relative to guidelines and, as such, there should be no consequences for public health.

PHE is committed to monitoring the evidence applicable to this and other radio technologies, and to revising its advice, should that be necessary.”

Germany: Federal Office for Radiation Protection (August 2018)

“If the limit values are adhered to, no health-relevant effects are to be expected according to the current scientific knowledge. However, with regard to the 5G planned use of additional frequency bands in the centi- and millimeter wavelength range, only a few results of the investigation are available. Here the BfS sees still need for research.”
BfS also repeats its existing recommendations for ‘prudent’ use of wireless devices including choosing a low SAR phone.

Finland: Radiation and Nuclear Safety Authority (January 2019)

“In the light of current information, exposure to radiofrequency radiation from base stations will not rise to a significant level with the introduction of the 5G network. From the point of view of exposure to radiofrequency radiation, the new base stations do not differ significantly from the base stations of existing mobile communication technologies (2G, 3G, 4G).”

USA: Federal Communication Commission (FCC) December 2019

“Despite requests from some to increase and others to decrease the existing limits, we believe they reflect the best available information concerning safe levels of RF exposure for workers and members of the general public, including inputs from our sister federal agencies charged with regulating safety and health and from well-established international standards”

Australia: Australian Radiation Protection and Nuclear Safety Agency (March 2019)

“At exposure levels below the limits set within the ARPANSA safety standard, it is the assessment of ARPANSA and international organisations such as the World Health Organisation (WHO) and the International Commission on Non-Ionising Radiation (ICNIRP) that there is no established scientific evidence to support any adverse health effects from very low RF EME [radiofrequency electromagnetic energy) exposures to populations or individuals.”

“Although the 5G mobile phone network is new, limits set in safety standards, our understanding of the evidence of health effects and the need for more research have not changed.”

Small cells are fully compliant with exposure guidelines at all distances so there is no requirement to label them.
