INTRODUCTION
A book entitled, "Mobile Phones
and Public Health - Myth and Reality" edited by Ravi V.S. Prasad and
published by Har-Anand Publications, New Delhi, 2014 was launched by Dr.
Michael Repacholi, Ex-head
of the EMF Project of the World Health Organisation (WHO) at Press Club, Mumbai on Dec. 2, 2013.
On
Jan. 9, 2014, there was a full page advertisement of the book in Hindustan
Times and Bombay Times of Times of India. My immediate reaction was, “Full page
advertisement of a book will cost lots of money, who is paying for it?”. I have
never seen a full page advertisement of any book in a national newspaper.
However, after reading the content of the advertisement, I could guess that
cell operators and their associates are behind this, who are trying to create
confusion in the minds of people and giving them false assurance that they are
safe from high cell tower radiation.
I
read the book and found my name has been mentioned several times in the book. I
am not a movie star or a cricketer or politician or business tycoon or Gandhiji
(most sought out people/names), then why my name has appeared at 12 places in a
book of 132 pages? Lots of questions started floating in my mind:
What
prompted the editor to compile this book?,
What
prompted various authors to write chapters of the book and what are their
backgrounds?,
Why
book was launched by Dr. Michael Repacholi
and who paid for his trip to India, why he was introduced by COAI people in the
press club?,
Why spend so much money on a full page
advertisement in major newspapers? and so on.
I
started reading the brief description about the editor and various authors and
also carried out Google search. I noted that some of them are associated with
cell phone/tower industries in one or other way, and some of them have never
worked in the areas of microwaves, antennas, microwave heating, biological
effects, etc., “So what makes them experts to write the chapters in the book?”
One thing which came out loud and
clear about "Why they love/hate me so much" because I have written
report on "Cell Tower Radiation", which was submitted to Secretary,
DOT in Dec. 2010, came out with two newsletters, conducted workshops and given
lectures to create awareness about "Cell phone/tower radiation hazards and
solutions". Obviously, these are not liked by cell phone/tower industry
people due to their business interest. They and their associates and
beneficiaries had been writing/telling at various forums in the past that there
are no evidence of any health hazards due to cell phone/tower radiation. After
WHO reported Cell phone as possibly carcinogen (Class 2B) on May 31, 2011, some
of these people now state that there are no concrete evidence of health
hazards. People should understand that "no concrete evidence" does
not mean "no evidence".
Most of the places, the book has
shown only one side of the coin or even part of one side of the coin, which is
pro cell operators and also tried to defame me and my credibility and completely
ignored several health hazards reported in 1000's of scientific papers. Through
this document, I want to show other side of the coin, so that people will get
complete picture. Let people see both sides of the coin and then decide what is
the truth.
The book entitled "Mobile
Phones and Public Health - Myths and reality", is edited by Ravi V.S.
Prasad, who has also written "Foreword", Chapter 8 and
"Afterword". It is collection of articles written by several people. It
starts with Foreword, followed by eight chapters, and ends with Afterword. It also
includes several Annexures.
BACKGROUND OF EDITOR AND CONTRIBUTORS OF THE BOOK
Let us start with Ravi V.S. Prasad,
editor of the book, who has also written "Foreword". The following
site gives details about him, which quotes, "Since
1995, Ravi Visvesvaraya’s articles in the [Hindustan Times], Telegraph,
Financial Express, and [Indian Express], and his appearances on CNBC and Jain Television, have been instrumental in spurring
the growth of India’s telecommunications sector, and several favorable
government policies can be credited to his lobbying."
http://www.thefullwiki.org/Ravi_Visvesvaraya_Sharada_Prasad
It is clear from the above that Ravi V.S. Prasad is a
lobbyist for telecom sector. Hence, he decided to be editor of this book, which
consists of articles favoring telecom industry.
First chapter
is written by Dr. Vasant Natarajan, Professor, Dept. of Physics, IISc
Bangalore. His research interests and
activities are: High-resolution spectroscopy; Absolute frequency
measurements; Quantum optics; Hyperfine-structure measurements; Laser cooling
and trapping of atoms; Search for electric dipole moment using laser-cooled Yb
atoms as a test of time-reversal symmetry violation; Ion trapping and its use
in quantum computation; Optical tweezers and trapping of single RBCs.
Second chapter
is written by Prof. Susanta Sen, Univ. of Calcutta. His research areas are:
Quantum and Optoelectronic Devices, OEIC, Instrumentation, VLSI Design. Third chapter is written by Dr. K.S. Parthasarathy, Former Secretary, Atomic Energy Regulatory Board.
Quantum and Optoelectronic Devices, OEIC, Instrumentation, VLSI Design. Third chapter is written by Dr. K.S. Parthasarathy, Former Secretary, Atomic Energy Regulatory Board.
It is obvious that all the above three contributors do not
have experience in the areas of microwaves, antennas, microwave heating,
biological effects, etc., so what makes them an expert to write a chapter in
this book.
Chapter 4
is written by Michael Repacholi, Ex-WHO, EMF project, 1995 till June 2006. He
was also Founding Member and Chairman of ICNIRP. A Google search reveals his role
and industry support, which are summarized as follows:
"Just
months after leaving his post as the head of the EMF project at the World
Health Organization (WHO), Mike Repacholi is now in business as an industry
consultant. He admits Interference from
the Industry at the World Health Organisation EMF Project. Not only did
Repacholi control the WHO EMF project from its inception, but its main source
of funding was Industry. Repacholi
arranged for the industry money to be sent to the Royal Adelaide Hospital in
Australia, where he used to work. The funds were then transferred to the WHO.
Norm Sandler, a Motorola spokesman, told that, “This is the process for all the
supporters of the WHO program.” At the time, Motorola was sending Repacholi $50,000 each year. That money is
now bundled with other industry contributions and sent to Australia by the
Mobile Manufacturers Forum (MMF), which gives the project $150,000 a year.
Funding
summary for the International EMF Project (July 2006 – June 2007) states that the INCOME
of $249,682 came from various
Governments and $529,820 from Others. The “Others”
is almost entirely sourced from the Royal Adelaide Hospital, and hence from
Industry. The indirect funding arrangement was terminated after Repacholi's
departure from the WHO.
With the source of WHO EMF Project
funding exposed, Repacholi's role in the WHO EMF Project explained and his continuing role of roving ambassador for
Industry, isn't it about time that people ignore Repacholi and the WHO
EMF Project reports (earlier than 2007) that industry representatives often
quote?"
Chapter 5
is written by
A J Swerdlow, and others. Google
search reveals "Prof. A J Swerdlow holds shares in the telecom companies
Cable and Wireless Worldwide and Cable and Wireless Communications and his wife
holds shares in the BT group, a global telecommunications services company".
Chapter 6
is written by Dr.
Jack Rowley, Senior Director, GSM Association. He represents GSM industry and
will try to influence and present the views, which are suited to the industry
than to the people.
Chapter 7
is written by Dr.
Bhavin Jankharia, Radiologist. It appears
that he does not have experience in the areas of microwaves, antennas,
microwave heating, biological effects, etc., so what makes him an expert to
write a chapter in this book.
Thus, some of the contributors are
associated with cell phone/tower industries in one or other way and some of
them have never worked in the areas of microwaves, antennas, microwave heating,
biological effects, etc., so they are not the right experts to write about
hazards of cell phone/tower radiation. Let us see what they have written, how
they are misleading the people by giving partial truth and conveying the
message that all is well, whereas in reality, extreme precautions and safety
measures are required to use cell phone technology safely.
COMMENTS ON RADIATION ISSUES
COVERED IN THE BOOK
Since many things are repeated by
authors in various chapters, I have summarized my comments under various
sub-headings to avoid repetition.
Comparison of Sun radiation versus cell tower
radiation
They compare sun
radiation with cell tower radiation and say sun radiation density is 1000 W/m2,
which is thousands of times larger than cell
tower radiation density of 0.1 W/m2.
Hence cell tower radiation is not harmful. They have also written that if you
place a container of water outdoors, it will not boil no matter how long it is
exposed to sunlight.
It is agreed that if one places a
container of water outdoors, it will not boil no matter how long it is exposed
to sunlight. However, if the same container of water is kept inside a microwave
oven, it will boil in a few minutes. Thus, even though sun intensity of 1000W/m2
cannot boil the water, yet 500W of microwave power can boil the water in a few
minutes. Even 1/10th of this power will boil the water in less than an hour, and
even 1/100th of this power (i.e. 5W) will boil the water in less than a day. There
is a different mechanism of heating. In case of microwave oven operating at a frequency of
2450 MHz, water molecules vibrate at a speed
of 2.45 billion times per second, which creates friction and leads to heating.
In many countries, frequency of 915MHz is also used for
industrial microwave heating.
Sun
exposure is not continuous whereas microwave radiation due to cell tower
radiation is 24x7. People do not stand in the sun for hours and clothes act as
protective shielding from sun. People who do sun bathing for long hours have
reported sun tanning, skin burning and even skin cancer. Sun radiation causes heating
from outside to inside. The skin of human body acts as an insulator from sun
and as the temperature increases, skin will either feel the burning sensation
or starts sweating. In addition, air breeze takes away the heat. Whereas, microwave radiation from cell phone
and cell tower penetrates the skin and at a frequency of 900 MHz, water
(including blood, fluid, etc.) molecule vibrate
at a speed of 900 million times per
second, which creates friction, damages DNA and also leads to heating. This heating is from
inside to outside and the heat is trapped inside the human body with no escape
through the skin. Also, affect of microwave radiation is cumulative in nature
and the harmful effects are noticed after a few months to a few years depending
upon the intensity of the radiation.
Human body consists of 70% liquid and brain contains 90%
liquid. When cell phone and cell tower radiation of GSM900 impinges on human
body, the water (including blood, fluids, etc.) inside the body vibrate at a
speed of 900 million times per second, which creates friction. This friction
damages the DNA and if damage to DNA is greater than DNA repair, it initiates
mutation and cancer.
Comparison of Ionizing radiation versus Non-Ionizing
radiation of cell phone/tower
The
authors, cell operators and their associates have been repeatedly
saying/writing/speaking at various forums that Ionizing radiation (UV Rays, X-Rays, Nuclear) can break the bond due to its higher frequency
and hence higher energy, whereas cell phone/tower radiation has much lesser
frequency and hence lower energy, which cannot break the bond and hence cannot
damage DNA or cause cancer.
It is agreed that ionizing radiation
(UV Rays, X-Rays, Nuclear) has higher frequency and hence higher energy,
which can break the bond and cause
significant damage to the human body, including cancer. However, the claim is
not correct that one cannot get any mutation (or damage) in the DNA (biological
reaction) due to cell phone frequencies, which is non-ionizing radiation. Even
though microwave frequency is less, which implies less energy due to the
equation Energy E = hxf, where h is Planck's constant and f is frequency.
However, all the world's phenomenon cannot be explained by a single equation of
physics. Energy is also defined as E = power x time, which is easily understood
and experienced by people. For example, standing for longer time in the sun,
one will feel more heated, so time is important. Also, standing in the sun
during noon and evening for the same time, one will feel more heated during
noon because sun intensity is more (in other words, power is more). In both the
above cases, only E = hxf will give same
value, and hence cannot explain the phenomenon, so one has to use E = power x time. It is unfortunate that only
first equation is used to explain and emphasize the view-points by totally
ignoring the second equation. Is it lack of knowledge or they trying to confuse
people by making statements, which are favorable to telecom industry.
I will like to quote Dr. Martin
Blank of Columbia University, past president of the Bio-electromagnetics
Society, "These physicists are thinking about what they know well—heating
effects on matter - but it's clear they need to start spending time with the
biologists! And they should certainly not be opining on this subject until they
have read the science on the biological effects of EMF at non-thermal exposures."

There are several references given in my report submitted to
Secretary, DOT in Dec. 2010. Also, large number of references are given in
Bio-Initiative Report 2012 (www.bioinitiative.org). On Page 47 of this 1479
pages report, it is mentioned, "In twenty-four technical chapters, the
contributing authors discuss the content and implications of about 1800 new
studies. Overall, these new studies report abnormal gene transcription (Section
5); genotoxicity and single-and double-strand DNA damage (Section 6); stress
proteins because of the fractal RF-antenna like nature of DNA (Section 7); chromatin
condensation and loss of DNA repair capacity in human stem cells (Sections 6
and 15)".
ICNIRP - Funding Questioned by People
India
had adopted ICNIRP (the International Commission on Non-Ionising Radiation
Protection) Guidelines in 2008. ICNIRP is an NGO, whose funding has been
questioned by large number of people.
Google search words as "ICNIRP funding" leads to several
websites:
The following paragraph is taken from
the site:
http://wiredchild.org/component/content/article/46-hidden/99-icnirp.html
"It
should be noted that ICNIRP is not a transparent organization. It has never
disclosed the sources of its funding nor the procedures for the selection of
its members. ICNIRP was established by Mike Repacholi, who has long had
financial ties to both the telecom and electric utility industries."
One
can see website of Dr. Magda Havas, Associate Professor, Environmental &
Resource Studies, Trent University, Peterborough, ON, Canada, at: http://www.magdahavas.com. She has uploaded
several reports, videos, etc. showing adverse effect of cell phone, cell tower
and wireless radiation. One can see "Conflict of Interest: the Wireless Industry and
ICNIRP" at:
http://www.magdahavas.com/conflict-of-interest-the-wireless-industry-and-icnirp/
Most
of the ICNIRP Guidelines are suited to the industry and hence widely publicized
by them. India adopted 1/10th of ICNIRP Guidelines from Sep. 1, 2012, which
implies safe radiation density of 450 milliWatts/m2 for GSM900, however,
these are still very high. For 24x7 exposure, safe radiation density should be
less than 1milliWatts/m2.
WHO reported Cell phones as “Possible
Human Carcinogen” (Class 2B) in May 2011
The authors,
cell operators and their associates make fun of WHO (World Health Organization)
Class 2B classification of cell phones and made statements that cell phone is
as dangerous as eating pickles and drinking coffee.
Let me ask, how
many times people eat pickles in a day, may be, maximum 2 to 3 times; how many
times people drink coffee, may be maximum 2 to 5 cups of coffee per day.
Similarly, using cell phones for up to 10 to 30 minutes may be safe depending
upon SAR value of the cell phone. Interphone study released in May 2010
reported 5,117 brain tumor cases and stated that people who use cell phones for
30 minutes per day over a duration of 8 to 10 years, have doubled to quadrupled
chances of getting brain tumor, and that's why it was classified as Class 2B.
WHO did not classify it as Class 3 or Class 4, which implies no evidence. Use
of cell phones is a personal choice but what about people who live in the
vicinity of cell towers, they are exposed to the radiation 24x7.
According to Dr.
Anthony Miller, who was on the IARC committee, the accumulated evidence is now
strong enough to suggest RF fields really should be classified as a 2A or
“probable carcinogen.”
A
study published in September 2013, “Case-control study of the association
between malignant brain tumors diagnosed between 2007 and 2009 and mobile and
cordless phone use” by Hardell et al also confirmed previously reported results
showing an association between cell phones and malignant brain tumors,
suggesting RFs from cell phones may play a role in both the initiation and
promotion of cancer.
And
another study by Hardell et al, published in December 2013 showed that the
evidence available suggests that RF-EMF exposure from mobile (and cordless)
phones should be regarded as an IARC class 1 human carcinogen. Alasdair Philips
of Powerwatch (U.K.) says, “The
criteria on strength, consistency, specificity, temporality, and biologic
gradient for evidence of increased risk for glioma and acoustic neuroma were
fulfilled.”
Thus, stronger
evidences are emerging and scientists are urging WHO that RF fields really
should be classified as Class 2A or “probable carcinogen” or even Class 1 or
"human carcinogen".
Non-Conclusive versus Conclusive
evidences of health hazards
The
authors, cell operators and their associates say there are no conclusive
evidences of health hazards due to cell phone and cell tower radiations.
Earlier,
they used to say "there is no evidence" but after large number of
scientific papers reported adverse health hazards, now they have started
saying, "there is no conclusive evidence". Do they want millions of
people to get affected before they accept, "it is conclusive" just
like cigarette industry?
Various
contributors have quoted studies and reports, which mention there are no health
hazards but why they have ignored thousands of papers stating there are health
hazards to the people, birds, animals, plants, trees, etc. Please see the
following link:
http://www.powerwatch.org.uk/science/studies.asp
The following text is taken from the front page of the link:
The following text is taken from the front page of the link:
When it comes to EMF issues, one of the most
frequently heard phrases is "There is no evidence to support EMFs having
health effects" or simply "There is no conclusive evidence".
We believe that
this is completely wrong; there is an enormous body of evidence out there, but
public and even academic awareness seems to be very poor. Therefore, we will be
presenting a list of papers and ORs which either show serious effects or are
considered important papers on the subject which we have collected over the
years. This page will be regularly added to.
P This study has
found effects from the exposure or radiation category
N This study has
found no effects from the exposure or radiation category
- This study has
offered important insights or findings but is neither a positive or null
finding
The
Bio-Initiative Report 2012 is prepared by 29 scientists and health experts from
10 countries and was uploaded in Jan. 2013 to create awareness. It is an update
of Bio-Initiative Report 2007, which was published by Bio-Initiative Working Group that looked at more than 2,000 peer
reviewed studies documenting bio-effects and adverse health effects from EMF
exposures. They recommended safe radiation density of 1 milliwatts/m2
for outdoor and 0.1 milliwatts/m2 for indoor continuous exposure.
Bio-Initiative 2012 assessed 1800 new research
papers (from 2006 to 2011) and mentioned that Bio-effects
are clearly established and occur at very low levels of exposure to
electromagnetic fields and radiofrequency radiation. Even at 0.03 milliwatts/m2,
researchers have reported headaches,
concentration difficulties and behavioral problems in children and adolescents;
and sleep disturbances, headaches and concentration problems in adults.
Cell phone/tower
industry criticized the report citing other reports and references. However, according to me, Bio-Initiative Reports of 2007 and
2012 are the most authentic reports on this subject, giving references of 3800
research papers, written by more than 1000 scientists, reviewed by equally
large number of experts and published in the prestigious journals.
Scaremongering Reports versus Awareness about Health Hazards
On Page 13 of the book, it is
written, "Most of the scaremongering reports in the media have been
spearheaded by Professor Girish Kumar of the Indian Institute of Technology,
Bombay."
Creating
awareness to the people about possible health hazards is important. I
had submitted my report on "Cell Tower Radiation", to Secretary, DOT
in Dec. 2010. It contained 30 pages of report and nearly 200
scientific/technical references. Also, gave presentation to Inter-Ministerial
Committee (IMC) at Delhi in Oct. 2010. IMC committee members interacted with
various stake holders (scientists, doctors, concerned citizen group, cell operators
and their associates, etc.), went through several
scientific/technical references and noted several health hazards, and finally
came out with a report in Jan. 2011. They recommended reduction of norms to
1/10th of ICNIRP Guidelines, but even this is very high for 24x7 exposure. I
conducted two workshops on "Cell Phone/Tower Radiation Hazards and
Solutions" at IIT Bombay on Nov. 20, 2011 and July 9, 2012. It was
attended by various scientists, doctors, concerned citizens, telecom industries
and their associates. I have also given lectures to create awareness about
"Cell phone/tower radiation hazards and solutions". Later on, I came out with two newsletters on "Cell
Phone/Tower Radiation Hazards and Solutions" in 2013, where I have given
several reported cancer cluster cases of people living in the vicinity of cell
towers, DOT Guidelines not sufficient to protect people, Global Studies, etc.
Obviously, these are not liked by cell phone/tower industry people due to their
business interest.
COMMENTS ON SOME OF THE
ANNEXURES IN THE BOOK
In Annexure I,
WHO Questions & Answers dated Sep. 20, 2013 states:
Q: What are the health risks
associated with mobile phones and their base stations?
A:
This is a question which WHO takes very seriously. Given the immense number of
people who use mobile phones, even a small increase in the incidence of adverse
effects on health could have major public health implications. Because exposure
to the radiofrequency (RF) fields emitted by mobile phones is generally more
than a 1000 times higher than from base stations, and the greater likelihood of
any adverse effect being due to handsets, research has almost exclusively been
conducted on possible effects of mobile phone exposure.
It is very important to note that
according to WHO, "RF fields emitted by mobile phones is generally more
than a 1000 times higher than from base stations", which implies base
station radiation is 1/1000th of mobile phones. I have measured radiation
density of cell phones in the Antenna Lab at IIT Bombay, the max. average value
is less than100 milliwatts/square meter, when cell phone is in the talk mode.
So, base station radiation should be 100/1000 = 0.1 milliwatts/square meter.
So, WHO answer implies that any adverse effect are less likely for cell tower
radiation less than 0.1 milliwatts/square meter. According to me and
Bio-Initiative report, less than 0.1 milliwatts/square meter is safe. However,
in India, we have adopted 450 milliwatts/square meter for 24x7 exposure.
Annexure VI
includes statement of President, Delhi Medical Association that "Radiation
from the mobile towers poses no threat to health.....WHO, which comes out fact
sheets from time to time". It is unfortunate that he has ignored Bio-Initiative
report 2012 and 1000's
of scientific papers reporting health hazards due to cell phone/ tower
radiation. Due to high radiation, people living in the vicinity are experiencing several health problems,
such as, sleep disorder, headache, lack of concentration, memory loss, eyes and
ears problems, joint problems, cardiovascular problems, miscarriage,
infertility, cancer, etc.
Guideline of the Austrian Medical Association for
the diagnosis and treatment of EMF related health problems and illnesses adopted on 3rd March 2012 in Vienna are:
Irrespective of the ICNIRP recommendations for acute effects, the
following benchmarks apply to regular exposure of more than four hours per day.
High-frequency electromagnetic
radiation (as power flow density)
·
≥1 mW/m2 -
very far above normal
·
0.01-1 mW/m2 - far above normal
·
0.001-0.01 mW/m2 - slightly above normal
·
≤0.001 mW/m2 - within normal limits
The benchmarks listed are intended to be applied to individual
types of radiation, e.g. GSM,
UMTS, WiMAX, TETRA, radio, TV, DECT or
WLAN, and refer to peak levels.
Annexure VII
includes statement of 24 IIT/IISc Professors on Indian Standards on EMF. They
have themselves mentioned, "some of our work has been funded by various
government agencies and by telecom operators.... have also been independent board
members of these companies."
There
are 8 Telecom Centers of Excellence (TCOE), which are
primarily funded by:
- Aircel at IISc Bengaluru
- Bharat Sanchar Nigam Ltd. (BSNL) at IIT, Kanpur
- Bharti Airtel at IIT Delhi
- Idea Cellular at IIM Ahmedabad
- Reliance Communications at IIT Madras
- Tata Teleservices at IIT Bombay
- Vodafone Essar at IIT Kharagpur
- RailTel at IIT Roorkee
The
telecom companies provide a major share, 90%, of the funding to TCOEs. At IIT Bombay,
Bharti Telecom has given US$ 1Million and Tata Teleservices has agreed to pay
Rs. 12 crores and approximately half of that amount has been received and
balance amount will come in a few years. Similarly, other TCOEs
receive crores of rupees of funding from the industry. Many of these professors
have been working in Industry sponsored Telecom Centers of Excellence. and some
of them have been board members of telecom companies, so their view-points support
DOT norms, which are beneficial to telecom industry. Also, majority of them
have worked on baseband, signal processing, network protocol, etc. and have not
worked on microwaves, antennas, microwave heating principle, biological
effects, etc. So, people
have to ask these professors, what makes them an expert to write such statement,
what studies they have carried out, how much funding they have received from
the telecom operators, why they ignored 1000's
of papers stating there are health hazards due to overuse of cell phones and
higher cell tower radiation, and so on.
(NOTE: I know many of these IIT Professors
and some of them are my friends. They have done great academic and research
work and have contributed immensely in imparting knowledge to the students and
contributing towards the growth of the country. However, it is unfortunate that
they issued the statement, which is favorable to the telecom industry and
ignored health hazards associated with high cell tower radiation, which is
affecting people, birds, animals, plants, trees, etc. I had no choice but to
issue this document as overuse of cell phones and high cell tower radiation concerns
health of the people and environment, which is more important from humanity
point of view).
Disclosure
My
daughter, Neha Kumar, has a company named, "NESA Radiation Solutions Pvt.
Ltd", which gives radiation shielding solutions to protect people from the
harmful effects of cell tower radiation. If Govt. adopts better radiation norms,
which will compel cell operators to reduce the transmitted power, then who will
need the shielding solutions?
