Percy Spencer was one of the scientists working on microwave
signals during the Second World War. These signals were used
by radar machines to detect enemy planes and submarines.
Whilst running these experiments, he once noticed that a
chocolate bar that he had in his pocket had melted. He
suspected that it may have something to do with the signals.
These were, after all, power waves that travelled huge
distances. Like a true scientist, he tested his theory with
other food items: egg and popcorn kernels. This was a good
choice of specimen as both food items undergo dramatic
changes when cooked. The eggs burst and the kernels popped.
And the microwave was born.
So powerful are these waves that they are bounced back from
the moon to measure its distance and study its topography.
Microwaves are finding increasing number of uses in today’s
wireless world. But no application of microwaves is as
pervasive as that for cell phones. Roughly four out of seven
billion people that populate the earth own a cell phone. In
most cities, the tele-density is over 100%, i.e. there are
more cell phone connections than there are people! With
calling rates in constant free-fall, the amount of time we
spend on the phone is only going to the increase. Worrying
about the effects of mobile phone radiation on the human
body is, therefore, justified.
The word radiation has a very negative connotation. From
nuclear meltdowns to comic book superpowers, radiation has
become synonymous with mutation and effects on health. Heat
emitted from electrical devices, visible sunlight and X-rays
used for medical imaging are all forms of radiation. They
differ in power and frequency. While X-rays, that are
definitely harmful, fall in the range of 1020 to 1022 GHz
(Giga Hertz), wireless devices like cell phones have a
maximum frequency of 300 GHz. A typical GSM cell phone
radiates power up to 2 watts. For comparison, consider the
humble light bulb. It radiates power to the tune of 25-100
watts. So, we are talking about very small amounts of energy
that is being absorbed by the human body. The concern is not
the amount of energy but the amount of exposure.
What studies say?
There have been numerous studies over the years but most
remain fashionably inconclusive. Those that lean one way or
the other are criticized for being partial. Mobile phone
radiation has been suspected to cause everything from lower
bone density to infertility and even fasten existing cancers
if not cause new ones. With mobile phone usage going through
the roof, one would think that if any of these suspicions
proved to be correct, we would have an epidemic of such
conditions. WHO’s official stance is to observe precautions
to guard against radiation as the studies carried out so far
leave enough room for reasonable doubt.
What observation should tell you?
What we cannot see does not scare us. Like a dentist
appointment next month or arctic melting. But you do feel
hot around the ear during long mobile phone conversations.
Temperature on the face can rise by a couple of degrees over
a 15 minute phone conversation. You can very much see the
disturbance on a computer screen or other devices when a
call is coming in. Some people are more sensitive to
electromagnetic fields and get headaches and insomnia
without even knowing what is causing them.
The most recent study published two months ago in The
Journal of the American Medical Association indicates that
being on a call for less than an hour can increase glucose
metabolism in the brain. What effects such a change might
have is a different issue. But the fact that mobile phone
usage causes changes in the body is pretty much certain.
This should be reason enough to be cautious.
