Why minimising ‘mobile’ conversations is a ‘no-brainer’
Did you know a cell phone in a moving car emits significantly greater
radiation, half of which could be absorbed by the brain while talking? A
renowned epidemiologist from the US warns users of this and other cell-phone
related hazards in the course of her recent talks in India. Darryl D’Monte
reports.

October 2014 -
Dr Devra Davis, a
well-known American epidemiologist, author and health activist, President
of Environmental Health Trust, a non-profit
organisation devoted to researching and controlling avoidable environmental
health threats, addressed a group consisting largely of Mumbai doctors
on 19 October, at the end of a gruelling three-week tour that included visits
to Delhi and Jaipur. This was in addition to three other talks in Mumbai
alone.
Davis is the author
of Disconnect: The Truth about Cell Phone Radiation, which has
also been published by Jaico this year with a foreword by Juhi Chawla Mehta,
the Bollywood star and philanthropist, who is one of Mumbai’s leading
campaigners for safe use of such ubiquitous devices.
The author mentioned
how proud she was as a first-time grandmother a decade ago to see her
10-month-old grandson crawl over to his father’s cell phone and switch it on.
She marvelled at the toddler’s ingenuity. Only after much research some years
later did she realise that the child was exposing himself to dangerously high
levels of radiation. In her book, she refers to Korean kids, addicted to
their phones, suffering from a form of brain damage known as “digital
dementia”.
Indeed, as a pamphlet
she distributed in Mumbai regarding precautions to take while using cell
phones stated, “children absorb more radiation than adults”. Models of
scans, courtesy of Prof Om P. Gandhi of the University of Utah and Green
America, contrast the brains of a five-year old, a 10-year-old and adult. The
potential absorption of radiation is very much higher the younger one is. As
Dr Davis punned, this is a “no-brainer”.
Parallels with the
microwave oven
The amount of
radiation depends on the frequency and amplitude of the waves. The
device that is most harmful is that which draws the maximum power. By that
token, microwave ovens, which use 1,000 watts, are the most dangerous, except
that the exposure is limited to a few minutes a day.
The invention of
microwave ovens came about accidentally, when scientists were working on how
to use radar technology for peaceful use after the Second World War. During
an experiment, a researcher found that the chocolate kept in his pocket had
melted, making him aware that such exposure generated heat. This led to the
domestic use of this appliance to heat or cook food.
The technology also
had to be adapted to rotate, so that all sides of anything to be cooked could
be covered. What might otherwise have been referred to as “radar
ranges” were renamed “microwave ovens”, which sounds more benign and
customer-friendly.
Davis makes the
frightening assertion that “cell phones are two-way microwave radios that
were never properly tested for safety”. Antennas for these phones are
continually searching for signals to send and receive information. “The body
or brain absorbs about half the radiation emitted from a phone at any time,”
she points out.
She particularly
cautioned against talking in a car due to the fact that the device constantly
searches for signals from the nearest cell tower and draws more power to
compensate for distance and mobility. Conversations in cars must account for
one of the longest uses of the phone by the well-to-do in this country,
considering the traffic snarls that grip every big city.
Radiation from cell
towers, inefficiently monitored in this country – thanks in part to the
effective lobbying of the phone industry and warnings that restrictions on
towers can lead to poor connectivity – is very dangerous, especially because
it is emitting 24x7 into homes that are too close for comfort.
Cell phones use less
than 2 watts, but there can be prolonged exposure, particularly given the
abysmal lack of knowledge among consumers here. We have been characterised as
a “cell phone nation”, with some 900 million users. In fact, there are more
phones than toilets or electricity connections. Davis hoped that the PM’s
“Make In India” exhortation would also lead to the development of safe phone
usage, which the rest of the world could learn from.

The hazards involved
A recent advertisement
for a mobile phone mentions that “every 7 seconds, someone upgrades to a
Gionee mobile…And right here in India. In a little over a year, we have 3
million happy users. And with each passing day, we are touching more hearts,
more rapidly.” The advertiser was supremely unaware about the literal
connotation of the possibly inadvertent last sentence.
According to
Davis, those who use phones more than 30 minutes a day on average for a
decade have a doubled or higher risk of contracting brain cancer.
Teenagers who start to use these phones – often inseparable companions, even
kept under their pillows at night – have a 4-5 times greater risk of
contracting such cancer.
Several studies have
shown that prolonged exposure to cell phone changes the brain. If someone
holds a phone to one’s ear for 50 minutes, there is a change in glucose
metabolism, which Davis terms “the brain’s fuel”, in exactly those areas
reached by cell phone radiation.
One reason why there
is so little data on the ill effects of cell phone radiation is that it can
take 40 years after such exposure to develop. This was conclusively shown in
Hiroshima and Nagasaki, when cancers in victims of the two atom bombs dropped
by the US over Japan took this long to manifest.
Experiments on
starving rats, which were trained to find their way through a maze by being
fed at the end of it, showed that they were too disoriented after exposure to
radiation to negotiate their way any longer.
A worrying development
is the rise in breast cancers among women who stuff their phones in their
bras. A Chinese-American 34-year-old in the US developed such cancer because
she stored it there for four hours a day. Racially, she had genes which are
not as a rule cancer-prone, and she was a regular runner to boot. In Turkey,
women who store their phones under their chadors have also been found to be
affected.
Men are by no means
immune to the risk. Six years ago, Dr Ashok Agarwal, Director of Research at
the Centre for Reproductive Medicine at the Cleveland Clinic, found that men
who use phones two to four hours every day have a 30 per cent lower sperm
count than non-users. Those who spoke for more than four hours had a 40 per
cent lower sperm count.
Prior to concerns
about cell phones, and even subsequently, men used to wear them
provocatively, in “gun-slinger” fashion – suspended from the belts around
their waists, which was far too close to their reproductive organs. If
nothing else, such findings, which impact males literally “below the belt”
and can give rise to testicular dysfunction and impotency, should arouse
awareness of the dangers of reckless use of phones.
Davis notes how the
user manuals of cell phones – always couched in the tiniest of print – do
specify warnings, which no one reads. The companies are merely meeting the
letter of the law in doing this. Thus, for instance, Blackberry warns
customers to keep phones an inch away from any part of the body whenever it
is turned on, “including the abdomen of pregnant women and the lower abdomen
of teen agers”. Apple cautions customers to keep its IPhone at least 15mm
(5/8 of an inch) away from the body.
A Global Campaign for
Safer Cell Phones lists several don’ts while using cell phones, which every
person ought to be aware of. These include:
·
Do
not hold the phone directly against your head or body; use the speaker phone
or other hands-free device
·
Beware
of a weak signal; your phone works harder and emits more radiation
·
Protect
children, pregnant women and prospective fathers
·
Never
sleep with your phone; keep it at more than an arm’s length
·
Only
corded – not cordless – phones do not emit microwave radiation
Davis cites how
tobacco companies obfuscated the dangers of smoking even though these were
known half a century before restrictions came into effect. In her 2009 book,The
Secret History of the War on Cancer, she reproduces an advertisement
showing a medic in a white coat with the text: “More doctors smoke Camel than
any other cigarette”. Another shows a baby urging its mother to smoke.
She is invariably
questioned what the alternative is, since people are loath to give up using
phones. The answer clearly lies in observing all the necessary precautions
and cutting the use to the minimum necessary. Prof Girish Kumar from the
Electrical Engineering Department of IIT Mumbai, who was present for two of
Davis’ talks, always mentions how he uses his phone for only 5 minutes a day
to receive messages. He shuts it off for the rest of the time.
Cell phone companies
should erect higher towers, well above the height of any buildings in the
vicinity, and there should be more towers, each less powerful, which would
obviously work out to be more expensive. However, Davis calculates that a
minuscule charge to customers of Rs 2 per month on the use of phones would
raise sufficient funds to provide all protective mechanisms necessary.
Is anybody listening?
