This letter
claims
the occurrence of brain cancer and certain types of tumors among cellular
phone users is twice that of non-users. Dr. Carlo is requesting AT&T's
assistance to distribute this information to consumers so that they can make
an "informed judgment about how much of this unknown risk they wish to
assume in their use of wireless phones."
A signed copy of this
letter was also sent to a panel of experts convened by the British
Parliament to evaluate the science and health concerns regarding wireless
communications.
7 October 1999
Mr. C. Michael Armstrong
Chairman and Chief Executive Officer
AT & T Corporation
32 Avenue of the Americas
New York, New York 100313-2412
Dear Mr. Armstrong:
After much thought, I am writing this letter to you, personally, to ask your
assistance in solving what I believe is an emerging and serious problem
concerning wireless phones. I write this letter in the interest of the more
than 80 million wireless phone users in the United States and the more than
200 million worldwide. But I also write this letter in the interest of your
industry, a critical part of our social and economic infrastructure.
Since 1993, I have headed the WTR surveillance and research program funded
by the wireless industry. The goal of WTR has always been to identify and
solve any problems concerning consumers' health that could arise from the
use of these phones. This past February, at the annual convention of the
CTIA, I met with the full board of that organization to brief them on some
surprising findings from our work. I do not recall if you were there
personally, but my understanding is that all segments of the industry were
represented.
At that briefing, I explained that the well-conducted scientific studies
that WTR was overseeing indicated that the question of wireless phone safety
had become confused.
Specifically, I reported to you that:
The rate of death from brain cancer among handheld phone users was higher
than the rate of brain cancer death among those who used non-handheld phones
that were away from their head;
The risk of acoustic neuroma, a benign tumour of the auditory nerve that is
well in range of the radiation coming from a phone's antenna system, was
fifty percent higher in people who reported using cell phones for six years
or more, moreover, that relationship between the amount of cell phone use
and this tumour appeared to follow a dose-response curve;
The risk of rare neuro epithelial tumours on the outside of the brain was
more than doubled, a statistically
significant risk increase, in cell phone users as compared to people who did
not use cell phones;
There appeared to be some correlation between brain tumours occurring on the
right side of the head and the use of the phone on the right side of the
head;
Laboratory studies looking at the ability of radiation from a phone's
antenna system to cause functional genetic damage were definitively
positive, and were following a dose-responsive relationship.
I also indicated that while our overall study of brain cancer occurrence did
not show a correlation with cell phone use, the vast majority of the tumours
that were studied were well out of range of the radiation that one would
expect from a cell phone's antenna. Because of that distance, the finding of
no effect was questionable. (Aegis Note: The entire phone is an antenna).
Such misclassification of radiation exposure would tend to dilute any real
effect that may have been present. In addition, I reported to you that the
genetic damage studies we conducted to look at the ability of radiation from
the phones to break DNA were negative, but that the positive finding of
functional DNA damage could be more important, perhaps indicating a problem
that is not dependent on DNA breakage, and that these inconsistencies needed
to be clarified. I reported that while none of these findings alone were
evidence of a definitive health hazard from wireless phones, the pattern of
potential health effects evidenced by different types of studies, from
different laboratories and by different investigators, raised serious
questions.
Following my presentation, I heard by voice vote of those present, a pledge
to "do the right thing in following up these findings" and a commitment of
the necessary funds.
When I took on the responsibility of doing this work for you, I pledged five
years. I was asked to continue on through the end of a sixth year, and
agreed. My tenure is now completed. My presentation to you and the CTIA
board in February was not an effort to lengthen my tenure at WTR, nor to
lengthen the tenure of WTR itself. I was simply doing my job of letting you
know what we found and what needed to be done following from our findings. I
made this expressly clear during my presentation to you and in many
subsequent conversations with members of your industry and the media.
Today, I sit here extremely frustrated and concerned that appropriate steps
have not been taken by the wireless industry to protect consumers during
this time of uncertainty about safety. The steps I am referring to were
specifically followed from the WTR program and have been recommended
repeatedly in public and private for and by me and other experts from around
the world. As I prepare to move away from the wireless phone issue and into
a different public health direction, I am concerned that the wireless
industry is missing a valuable opportunity by dealing with these public
health concerns through politics, creating illusions that more research over
the next several years helps consumers today, and false claims that
regulatory compliance means safety. The better choice by the wireless
industry would be to implement measured steps aimed at true consumer
protection.
Alarmingly, indications are that some segments of the industry have ignored
the scientific findings suggesting potential health effects, have repeatedly
and falsely claimed that wireless phones are safe for all consumers
including children, and have created an illusion of responsible follow up by
calling for and supporting more research. The most important measures of
consumer protection are missing: complete and honest factual information to
allow informed judgment by consumers about assumption of risk; the direct
tracking and monitoring of what happens to consumers who use wireless
phones; and, the monitoring of changes in the technology that could impact
health.
I am especially concerned about what appear to be actions by a segment of
the industry to conscript the FCC, the FDA and The World Health Organization
with them in following a non-effectual course that will likely result in a
regulatory and consumer backlash.
As an industry, you will have to deal with the fallout from all of your
choices, good and bad, in the long term. But short term, I would like your
help in effectuating an important public health intervention today.
The question of wireless phone safety is unclear. Therefore, from a public
health perspective, it is critical for consumers to have the information
they need to make an informed judgment about how much of this unknown risk
they wish to assume in their use of wireless phones.
Informing consumers openly
and honestly about what is known and not-known about health risks is not
liability laden - it is evidence that your industry is being responsible,
and doing all it can to assure safe use of its products. The current popular
backlash we are witnessing in the United States today against the tobacco
industry is derived in large part from perceived dishonesty on the part of
that industry in not being forthright about health effects. I urge you to
help your industry not repeat that mistake.
As we close out the business of the WTR, I would like to openly ask for your
help in distributing the summary findings we have complied of our work. This
last action is what always has been anticipated and forecast in the WTR's
research agenda. I have asked another organization with which I am
affiliated, The Health Risk Management Group (HRMG), to help us with this
public health intervention step, and to put together a consumer information
package for widespread distribution. Because neither WTR nor HRMG have the
means to effectuate this intervention, I am asking you to help us do the
right thing.
I would be happy to talk to you personally about this.
Sincerely yours
George L. Carlo Ph.D, M.S., J.D
Chairman
