A major review on the health effects of electromagnetic fields on workers
and residents has been produced by the California State Public Health
Department and represents nine years of research. It was made public in
2002. This report cost about US$7M. The research team was headed by three
epidemiologists from the California Health Department.
A draft review report was sent around the world to independent
epidemiologists and industry-connected epidemiologists asking them to
assess the level of evidence for each of the health effects they were
looking at.
Meetings with staff at the University of Berne
Dr Cherry learnt about the research when in Switzerland last October during
interviews with Professor Theo Abelin, one of the world's leading
epidemiologists and an independent academic. He has recently retired from
the University of Berne where he taught and researched preventative and
social medicine. Professor Abelin mentioned to Dr Cherry that he was one
of the epidemiologists from around the world working through the report and
giving a professional opinion on it.
At the University of Berne Dr Cherry found that researchers there were
unaware of the extent of his own research. They asked him, in the context
of other discussions, about the number of studies that showed chromosome
damage, melatonin reduction or DNA damage, and were amazed at how many
studies he had showing those effects that were shown in their own research
on sleep around the short wave radio tower in Schwarzenburg.
They had also done a study of brain cancer and leukaemia in electric train
drivers and found a significant relationship between the electromagnetic
fields in the trains and the drivers with leukaemia or brain cancer. They
asked about the biological mechanisms and were very surprised that Dr
Cherry had available information about so many studies supporting their
results. This is just one example of the way in which he has integrated
the knowledge reported by researchers and been able to share it with
colleagues around the world.
Some important interconnections omitted from the review from California
This is a major review of the published evidence on the dangers of
electromagnetic radiation. Dr Cherry considers that it is very good that
on the one hand they have said that there is very strong evidence of an
increase in the rates of child leukaemia, adult brain cancer, Lou Gehrig's
disease which is motor neurone disease, and miscarriage. On the other hand
they do not appreciate and understand that these fields are genotoxic and
reduce melatonin and damage DNA, which are the mechanisms behind these
accepted effects and dozens of other effects which they dismiss. They do
not appreciate the interconnections.
For example the evidence is very strong about cardiac illness and death,
because if the heart cells are damaged heart disease results - but this is
not accepted in the report. Nor does the review accept the strong evidence
for the connection between electromagnetic fields and depression and
suicide which are both caused by reduced melatonin. Both have been shown
to have increased significantly in electricity workers or people living
near power lines in a dose response manner. These two mechanisms also
affect the immune system and this has an effect on asthma which was shown
to be affected by power lines in Auckland, New Zealand Anxiety, depression
and other neurological illnesses were similarly affected. The published
paper recording this research is by Ivan Beale et al. 1997. Ivan Beale was
Associate Professor Psychology at the University of Auckland and until
recently the independent member of the Standards Committee. When he
resigned Dr Cherry took his place as an independent academic.
In all the studies the severity of the illness is dose related. In the
context of all the other evidence the illnesses are causally related to the
exposure to electromagnetic fields.
The American Electric Utility Workers Studies have shown dose-response
increases in cardiac death, suicide, leukaemia, and brain cancer.
Having collected so many studies Dr Cherry is more aware than many of the
researchers of the integration of the discoveries - how the scientific
pattern is explained if the connecting mechanisms are understood. The data
is assessed in a more open manner making clear cause and effect to anyone
who understands how factors interact.
Dr Cherry believes that his approach is nearer to that of people who study
chemicals and will say that some chemicals are carcinogenic and study those
needing classification by looking at the known data. If there is evidence
that exposed workers get more cancer then they would say "Yes, what they
are exposed to is carcinogenic."
Dr Cherry says, "People will say that chemicals are different because you
can see and smell and taste them, but I can see in my mind these
electromagnetic fields because I am very aware of them as a scientist. I
can measure them and I can see the wires that produce them. I can see the
DNA damage and the melatonin reduction occurring, and therefore I can see
how the heart, the brain, the lungs and the immune system are affected, how
the bone marrow is affected producing lymphoma and leukaemia. Thus I have
the same approach as the people looking at chemicals because I know the
biological mechanisms that produce all these health effects.
"People don't realise that just because there is strong evidence of
childhood leukaemia, brain cancer, miscarriage and motor neurone disease
which the review from California accepts, these are not separate effects,
but linked effects, along with many others."
