Does Increasing Use Of Cell-Phone & Wi-Fi Radiation Pose An Increasing Health Risk?
A 2016 talk by an engineer gives a “wake-up call” about-the danger of cell-phone use and Wi-Fi radiation. It is titled: Wireless wake-up call | Jeromy Johnson | TEDxBerkeley
A Silicon-valley engineer turned technology-health advocate, Jeromy Johnson discusses our attachment to technology.
This video is once again making the e-mail rounds. Some of you may have
seen this before, and our discussion then. Such talks are found in the
internet all the time. Of course, it is better to be safe than sorry,
and so one may wish to take some precautions if the risk is substantial.
But is it?
At every stage of human existence, humans had to judge the amount of
risk they have to face, in order to exist and move forward. This was
true for the hunter gatherers as well as the first people who learnt how
to tame fire.
Is the radiation from smart power meters, cell phones, home wif-fi etc.
dangerous, carcinogenic, or capable of causing nausea, sleeplessness
etc, and incapacitate you as stated in these reports?
The main-stream professional and scientific organizations do not support
the view that there is any risk from Wi-Fi radiation. Of course, the
frightened public will immediately point out to examples of collusion
between industry and scientific regulatory bodies. This can be
significant in the USA where Capitalism is King. Nevertheless, when
the professional and academic associations of a majority of countries
say the same thing, I prefer to follow main-stream science instead of
claims made by small, seemingly very concerned groups using anecdotal
accounts.
So let us look at the science from the main-stream point of view.
The American Cancer Association, and other professional associations do
not support the view that radiation from smart meters or cell phones
cause cancer.
Smart Meters transmit the reading to the power company at frequent
intervals (e.g., every hour or in full real time). See, for example, the ACA’s comments on smart meters.
The amount of radiation that we get from the sun at all frequencies is a
usually many times higher than what comes from these devices and from
cell phones. The sun radiates at low frequencies as well as at very high
frequencies, and it is the very high frequencies (short wavelengths)
that are most dangerous, compared to Wi-Fi and radio waves.
1. Johnson’s
argument that the radiation density has substantially increased because
of Wi-Fi is not correct. Typical cell-phone or smart-meter radiation is
at 2.4 GHz which is about 12.5 cm. The sun radiates at wavelengths of
100 nanometers to about 1 mm strongly, and beyond into radio frequencies
as well. So it is radiating in the Wi-Fi range as well. In fact, 52% of
the sun’s radiant energy is in the near infra red and millimeter range.
A Wi-Fi wave of 12.5 cm is more than 10 million times larger than a
micron sized cell in the body or in the brain. Think of a boat in the
ocean, and a wave which takes a very long time to swell up because its
wavelength is a million times longer than the boat. The boat merely
gets gently lifted up, and nothing happens. It is only if the wavelength
is comparable to the boat and turbulent (i.e., many short wavelengths
and eddies mixed up with long ones) that the boat gets into trouble. So
Wi-Fi radiation, which is largely monochromatic (single wavelength) near
12.5 cm cannot latch onto the electric circuits of the cell either due
to size based electrodynamic effects, Q-cavity effects, or due to
resonance effects unlike a cell phone which “picks up” the wave as it is
constructed to have a circuit in resonance with the 12.5 radiation.
One may imagine that if the wave were very strong (i.e.,if it had a
large amplitude), as wold be the case near a Wi-Fi tower, then its
effect would be correspondingly stronger. This is in fact not so, as
Einstein showed in 1905. Unlike with ordinary water waves or sound
waves, it is the quantum theory that controls the interaction of
radiation with matter, and here it is the frequency, and not the amplitude that matters.
2. The total number of cell phones and Wi-Fi sources in the world is
over 5 billion according to some estimates. Such radiation is in my view
a negligible increment over the existing background. But you can make
your own estimates. Also, such cell phones have existed now for several
decades. Scientists haven’t still been able to pin point any cases
(e.g., of brain cancer) exactly linked to the illness and the presence
of cell phone radiation – i.e., there is no evidence. There has been NO INCREASE in brain cancer while the amount of Wi-Fi has increased exponentially. In fact the incidence of brain cancer in the US has slightly decreased, over the years.
2. Of the 3 billion users, let us say we have perhaps a some thousands
of people who complain of nausea, inability to sleep etc., as stated by
this engineer Jeromy Johnson. He refers to a paper by an Australian
Doctor Frederica Lamech published in 2014 in a fringe journal known as “Alternative therapies“.
The report is anecdotal, and does not compare a group of patients with a
control group. There are many such reports, published in “predatory”
journals which have no scientific standing, and reveal poor
“experiments” that are simply not up to scientific standards. We have
the same problem in many environmental studies. A most notorious case is
that of a Sri Lankan Psychic Lady from kelaniya publishing a paper
with academics from the Rajarata University, claiming that kidney
disease in the Rajarata is caused by arsenic acting together with
residues of the herbicide glyphosateclaimed
to present in the hard water of the region. No evidence was presented,
but a “hypothesis” was published in a predatory journal. The journal
had no connection with a learned society or professional body, but it is
maintained by a Chinese businessman who publishes what is sent to the
journal as long as you pay a page charge, although there may even be a
pretense of “peer review”..
Do you know of ANYONE who has faced the conditions described by Engineer
Johnson that you can be ascribed to the use of a cell phone? Most
people don’t.
However, let us we assume that there is actually a problem, and that
5,000 such people have been definitively identified, and that there are 5
billion sources of Wi-Fi radiation in the world. Then we have 5,000/(5
billion) = 5/5000,000,000 gives us one chance in a million that this is
probably going to affect us within the next decade. There is a much
bigger risk from second hand smoke, and an even bigger risk from fumes
from motor vehicles, or falling in your bath tub. The risk for getting
hit in the street by a car and dying is about 30 times higher (for New
York, and much higher in Colombo or Cairo). Ten times more kids are
killed in bath tub accidents in the US alone, compared to the 5000 that
we assumed here. That figure may be contested. If so, any one is free to
use their own figures and make the risk calculation, and do it in a
more sophisticated way using advanced notions of probability
distributions etc.
4. So, even if the fringe science reports are not up to standard, it is
important to check if there is a danger, by carrying out good
experiments with double-blind controls. The WHO has sponsored or carried
out several such studies on the effect of cell phone radiation. In
2015, the European-Commission Scientific Committee on Emerging and Newly
Identified Health Risks concluded that, overall, the epidemiological
studies on cell phone radio-frequency electromagnetic radiation exposure
do not show an increased risk of brain tumors or of other cancers of
the head and neck region.

This is a WHO fact sheet that outlines the available evidence regarding
use of cellular/mobile telephones and cancer risk, but does not indicate
a definite risk. And yet this engineer seems to say that the WHO
arrived at the opposite conclusion. So what he says is, in my view,
incorrect.
