Q & A
What is electricity and how does it relate to our daily lives?
-Electricity is the movement of an electric charge, which generates electric and magnetic fields that spread out through space and carry energy. It is the foundation of the modern world, making our lives easier, safer, and more enjoyable, yet many people don't think much about it.
What is electromagnetic radiation and why does the word 'radiation' make people nervous?
-Electromagnetic radiation is the phenomenon where electric and magnetic fields spread out through space, carrying energy. The term 'radiation' can be alarming because it is often associated with harmful types of radiation, such as UV light, X-rays, and gamma rays, which can cause damage at the molecular level.
Which types of electromagnetic radiation are considered harmless and why?
-Longer wavelength radiation such as visible light, infrared, microwaves, and radio waves are generally considered harmless because they do not have enough energy to ionize atoms or molecules, and thus do not cause burns or genetic damage.
How does the radiation from mobile phones and Wi-Fi routers differ from harmful radiation?
-The radiation emitted by mobile phones and Wi-Fi routers falls into the category of non-ionizing radiation, which does not have enough energy to remove electrons from atoms, and therefore does not cause the kind of damage associated with harmful radiation like UV light or X-rays.
What is the Nocebo Effect and how might it relate to people feeling unwell from electromagnetic radiation?
-The Nocebo Effect is a phenomenon where negative expectations or beliefs about a treatment or exposure can lead to the experience of adverse effects, even if the exposure itself is not harmful. People who believe that electromagnetic radiation is harmful might experience symptoms like headaches or nausea due to this psychological effect, rather than the radiation itself.
What was the significance of the 1979 study that linked leukemia to living near power lines?
-The 1979 study was significant because it first brought public attention to the potential dangers of electromagnetic radiation. However, the study was discredited as it could not establish a direct causal link, and the connection between leukemia and living near power lines was not substantiated.
What is the current scientific consensus on the health effects of electromagnetic radiation from everyday devices like laptops and cell phones?
-The current scientific consensus is that there is no consistent evidence showing that electromagnetic radiation from everyday devices, when below exposure value limits, causes health problems. While some statistical associations exist, they are generally weak and inconsistent.
Why is it important to critically evaluate studies that claim to find a link between radiation and health issues?
-It is important to critically evaluate such studies because they can be based on unreliable self-reporting, may cherry-pick findings, or have other methodological flaws. Misinterpretation or sensationalization of study results can lead to unnecessary public panic and distract from more pressing health concerns.
What does the WHO's classification of radio frequency fields as 'possibly carcinogenic' actually mean?
-The WHO's classification as 'possibly carcinogenic' means that there are some hints or limited evidence suggesting that radio frequency fields might cause cancer, but there is not enough evidence to establish a definite causal relationship. It indicates a need for further research and monitoring.
What is the Cosmos study and why is it significant?
-The Cosmos study is a long-term research project that aims to investigate the potential health impacts of cell phone use by precisely measuring the frequency and duration of phone calls. It is significant because it seeks to provide more definitive evidence on the safety of cell phone radiation.
Why is it suggested that we focus on more pressing problems while waiting for the conclusion of long-term studies on electromagnetic radiation?
-It is suggested because, based on the current state of science, there is no robust evidence linking everyday exposure to electromagnetic radiation with negative health effects. In the meantime, there are other well-established health risks, such as outdoor air pollution, that have a significant impact and require immediate attention.

Transcripts
Electricity is all around us all the time.
It makes our lives easier, safer, more fun,
and most of us never think about it.
But is there such a thing as too much electricity?
Could the thing that is the foundation of the modern world
slowly be killing us?
Before we dive deeper,
let's try to understand what electricity is,
and how it affects us.
Electricity is the movement of an electric charge.
This movement generates Electric and Magnetic Fields
that spread out through space and carry energy.
We call this phenomenon: Electromagnetic Radiation.
Radiation is a word that makes people very nervous.
But, to radiate just means, "giving off".
Like when the radiator in your house gives off heat
in the form of infrared radiation.
Different parts of the electromagnetic spectrum
correspond to different types of radiation.
And, many of them are perfectly harmless.
Some of them can be dangerous though.
Radiation with very short wavelengths
like UV Light, X-Rays, and Gamma Rays
are strong enough to rip electrons out of their atoms,
which can cause burns and genetic damage.
This is what many people have in mind when they hear the term "radiation".
The rest of the spectrum covers a large range of longer waves
from Visible Light, Infrared,
Microwaves, to Radio Waves.
This is the kind of radiation that's emitted by all sorts of human technology.
Mobile phones, Wi-Fi routers,
electric power lines, and household appliances.
This radiation doesn't disrupt molecules in our body.
However, some kinds of radiation can stimulate muscles and nerves
and can also make the hair on your body vibrate,
which can sometimes cause a tingly feeling above certain threshold values.
Other kinds are useful for making dinner.
Microwaves push the water molecules in your food around
which warms it up.
This happens to us all the time.
For example, the pleasant warmth you feel at the beach
is your skin heating up from exposure to
electromagnetic infrared radiation from the sun.
We are surrounded by natural, and generally harmless,
sources of electromagnetic radiation all the time
and always have been.
But, since the Industrial Revolution,
we have added a lot of it to our immediate environment.
The question of whether this is actually dangerous
first got public attention when a 1979 study
linked leukemia to living near power lines.
This particular study was quickly discredited though.
The connection could not be explained
and no direct causal link was confirmed.
But once this had been proposed, the idea persisted.
And the thousands of studies about possible dangers
illustrate that it's still seen as a very real threat.
A lot of people claim to be sensitive to the radiation
coming from our appliances and cell phones.
They report symptoms like headaches,
nausea, skin reactions,
burning eyes, or exhaustion.
But those are just effects reported on a day-to-day basis.
A few studies have found much more unsettling results.
Like, possible connections between the side of the brain,
which people use when they are on their phones,
and the appearance of brain tumors.
The question that science is trying to answer,
is not so much about the acute effects of irradiation.
We know, for example,
that x-rays cause immediate damage to the DNA in your cells
but that the same doesn't happen with radio waves.
The question is rather:
Is the sort of weak electromagnetic radiation we are constantly surrounded by
harmful in the long run as a result of some as-yet-unknown mechanism?
Answering this question was much harder than we first thought.
There are thousands of primary sources,
reports, and statements by an onslaught of different organizations.
So, we read a lot for this video.
You can take a look at our research in the video description.
What we found is that this debate is a good example
of how science should be communicated and how it shouldn't.
Many of the much-cited studies that spread panic about electromagnetic radiation
are highly controversial.
For example,
a series of population studies based on surveys and self-reporting.
What this means is, for example,
asking brain tumor patients how much they think they used their phone in the last few years.
The problem is that people are unreliable.
We tend to misremember things or can be influenced easily.
On top of this,
studies or media reports may be cherry picking the findings that best suit their opinion
or make for the most exciting headline.
For example,
a study looking for cancer in rats and mice from cell phone radiation.
The results seemed to show a connection.
But, for some reason, only in male rats.
And, none at all in mice.
But it was reported as if this study did prove
that mobile phone radiation causes cancer.
Unfortunately, this is the case for studies with both positive and negative findings on the issue.
Another aspect, is that the WHO did officially classify radio frequency fields
as possibly carcinogenic.
But what this actually means
is that there are some hints that they might cause cancer,
but we can't prove it, and that we will keep an eye out.
So, if we zoom out a bit, what's the big picture?
On the whole,
there was no consistent evidence in human studies
that electromagnetic radiation below exposure value limits causes health problems.
There are some statistical associations
but they're mostly weak and inconsistent.
If there were any definite cause-effect relations
we would know by now because of all the data we have.
So, based on the current state of science,
should you worry about the radiation from your laptop, or cell phone, or TV?
The answer is no.
You shouldn't.
But what about the people who say it is harming them?
Research show they could be experiencing what's known as the Nocebo Effect.
If you have a headache and happen to start feeling better right when you switch off your laptop,
you might see a connection between those two things.
Once you get this suspicion, the idea alone that weak radiation might harm you
could be the very thing harming you.
It's easy to belittle these people;
most of them feel they're not being taken seriously,
which makes the situation even worse for them.
They should get support.
But, it's important to be aware that, so far,
we have no robust evidence that electricity below safety limits has any negative effect on humans.
In the attention economy we live in,
talking about unproven dangers can make us neglect things that we know for sure are bad for us.
Just one example:
Outdoor air pollution is linked to 4.2 million premature deaths each year,
and is definitely something we could have a real impact on today.
Still, to make people feel safe, and just to make sure,
there are several long-term studies ongoing already.
For example, the Cosmos study that will look at the possible health impacts of cell phone use
by exactly measuring frequency and duration of phone calls.
But while we wait for the conclusion of these long-term studies,
there are a lot more pressing problems to focus on.
