Right now, you are reading these lines on the screen of a mobile phone, tablet, or computer. For decades now, our access to huge amounts of information and instant communication has depended on antennas and transmitters that bathe our surroundings in radiation – specifically, in non-ionising electromagnetic radiation.
However, many people are concerned that this poses a health risk – you have doubtless heard that it is better to turn off your mobile phone or wifi while you sleep, that living near a cell tower can cause cancer, or that some people are especially sensitive to the radiation they emit.
Such feelings of fear or trepidation are a normal response to things we know are there but cannot see or feel in any way. For this reason, Spain’s Scientific Advisory Committee on Radio Frequencies and Health (CCARS, by its Spanish acronym) regularly publishes comprehensive reviews of all available scientific evidence on these types of radiation. By doing so, we aim to guarantee that this technology is safe for all of us.
CCARS has published seven reports since 2008. Here, we are going to look at the findings from our most recent report, published last year.
25 years reviewing the evidence
Since 1999, CCARS, a committee made up of independent scientists, has been responsible for reviewing the available evidence on cell tower radiation. Every 2 to 3 years, they have published reports to address questions of how we can exist safely and securely alongside our mobile and wireless devices.
Each generation of new phone technology has led to fresh doubts, meaning this debate is being continually reopened and reassessed, and the most recent development, 5G, has been no exception. Since its roll-out coincided with the Covid-19 pandemic, it was accompanied by all manner of conspiracies and falsehoods, notably that it was causing or spreading the pandemic, and that vaccines contained computer chips that would allow us to be controlled from a distance via 5G technology.
The committee reviewed all the evidence published in scientific journals between 2020 and 2022. This is normal and positive in science, where changes in knowledge can modify previously established understandings. This is why we must systematically and periodically review all new information, and remain vigilant of any changes.
