Hi

Can anyone help. I am trying to contact anyone who can advise about
proximity of buildings to power lines.

Does anyone know who I could speak to?

Kind regards,

Nel

| So, "there is no evidence that electromagnetic fields do not cause

It wouldn't bust your ass if you did some research yourself Jeff.
Maybe this will help you along.

DOES ELECTRICITY CAUSE CANCER?
Advice by the CEO of the Australian Radiation Protection and Nuclear
Safety Agency –

March 2001
1. Introduction
The Advisory Group on Non-Ionising Radiation (AGNIR) to the UK
National Radiological Protection Board has published a report on
power frequency electromagnetic fields and the risk of cancer (1).

Prior to the publication of this report, there was substantial media
interest in Australia as to what had been suggested (misleadingly) to
be its conclusions: that there was a link between high voltage power
lines and cancer, especially childhood leukaemia. I undertook to
provide early advice on the report as soon as it was released.

The report reviews scientific research published since an earlier
review by AGNIR of this topic in 1992-1994. It contains detailed
reviews of:
· sources and measurements of electromagnetic fields
· biological studies on cells relevant to cancer induction
· animal and volunteer studies relevant to cancer induction
· epidemiological studies on domestic exposure to electromagnetic
fields; and
· occupational exposures.

The overall main conclusion of the report deserves to be quoted in
full:

“Laboratory experiments have provided no good evidence that
extremely low frequency electromagnetic fields are capable of
producing cancer, nor do human epidemiological studies suggest that
they cause cancer in general. There is, however, some epidemiological
evidence that prolonged exposure to higher levels of power frequency
magnetic fields is associated with a small risk of leukaemia in
children. In practice, such levels of exposure are seldom encountered
by the general public in the UK. In the absence of clear evidence of
a carcinogenic effect in adults, or of a plausible explanation from
experiments on animals or isolated cells, the epidemiological
evidence is currently not strong enough to justify a firm conclusion
that such fields cause leukaemia in children. Unless, however,
further research indicates that the findingis due to chance or some
currently unrecognised artefact, the possibility remains that intense
and prolonged exposure to magnetic fields can increase the risk of
leukaemia in children.”

The elements that make up this complex conclusion are worth drawing
out:

· laboratory experiments have provided no good evidence that ELF EM
fields are capable of producing cancer;
· human epidemiological studies do not suggest that such fields cause
cancer in general;
· there is, however, some epidemiological evidence that prolonged
exposure to higher levels of ELF magnetic fields is associated with a
small risk of leukaemia in children;
· the evidence is not strong enough to justify a firm conclusion that
such fields cause leukaemia in children;
· but that possibility remains.

Importantly, the report indicates that, in adults who are
occupationally exposed, a causal relationship between EM field
exposure and tumour incidence at any site is not established.

The Advisory Group notes that considerable advances have been made in
methods for assessing exposure to electromagnetic fields, both in the
case of experimental studies and in epidemiological investigations.
It notes that this has provided a substantially improved basis for
many of the epidemiological studies reviewed by the Group.

With respect to studies at the cellular level, the report states that
there is no clear evidence that such exposure, at levels that are
likely to be encountered, can affect biological processes. There is
no convincing evidence that exposure to these fields is directly
genotoxic or can bring about the transformation of cells in culture
and thus the fields are unlikely to initiate carcinogenesis. Many of
the effects reported occurred with exposure to fields at high levels
that are unlikely to be sustained in a residential situation.

Turning to animal and volunteer studies, the report concludes again
that there is no convincing evidence from its review of a large
number of animal studies to support the hypothesis that exposure to
ELF EM fields increases the risk of cancer. Volunteer studies have
focused on impacts on the hormone melatonin and its role as a
possible natural tumour suppressor and on any possible inhibitory
effect of power frequency magnetic field exposure on those aspects of
immune system function relevant to tumour suppression.

The report then turns to evaluation of epidemiological studies2 of
residential exposure to ELF magnetic fields. The suggestion that
there may be a link between exposure to such magnetic field and
childhood cancer has been made for over 20 years and the subject has
been extensively studied. The most recent evidence on which the AGNIR
relies to a substantial extent for its conclusions is a pooled
analysis of nine studies in a number of countries

(2). Taken together, they suggest that prolonged exposure above 0.4
microtesla3 is associated with a doubling of the riskof leukemia in
children under 15 years of age.

The nine studies that were pooled included 3247 children with
leukaemia and 10,400 control children. The positive result of a
relative risk of two, with a confidence interval from 1.27 to 3.13,
occurred in the group with exposure level above 0.4 microtesla. This
group included just 44 children with leukaemia and 62 controls. The
study adjusted for a number of potential confounding variables:
socio-economic class, urbanization, type of dwelling, mobility, and
level of traffic exhaust. These adjustments did not appreciably
change the results.

It is illustrative of the complexity of the field to note that the
single largest study included in the pooled analysis was the UK
Childhood Cancer Study – at the time of its publication it was stated
that it found no link between overhead power cables and childhood
cancer.

The AGNIR report points out the limitations of the pooled analysis
that make the evidence not conclusive. In the majority of the
projects grouped together in the analysis, direct measurements were
made of the magnetic field exposures but there is some doubt about
whether the control groups in these studies were representative of
children from low socio-economic backgrounds. A number of projects
were carried out in the Nordic countries using population registers
that avoided this issue of representativeness, but in these cases the
fields were estimated, rather than measured.

3. What Do Other Authorities Say?

In May 1999, the Director of the US National Institute of
Environmental Health Sciences (NIEHS) brought forward a report on
“Health Effects from Exposure to Power-line Frequency Electric and
Magnetic Fields” (3). The preparation of this report had been
required by an Act passed by the US Congress in 1992 and it drew upon
a research and evaluation program (EMFRAPID) conducted by NIEHS with
the support of other US agencies.

A conclusion of the NIEHS report was:

“that ELF-EMF exposure cannot be recognised at this time as entirely
safe because of weak scientific evidence that exposure may pose a
leukemia hazard. In my opinion, the conclusion of this report is
insufficient to warrant aggressive regulatory concerns. However,
because everyone in the United States uses electricity and therefore
is routinely exposed to ELF-EMF, passive regulatory action is
warranted, such as a continued emphasis on educating both the public
and the regulated community on means aimed at reducing exposure.”

As did AGNIR, the NIEHS reached this conclusion on the basis of
epidemiological studies:

“While the support from individual studies is weak, the
epidemiological studies demonstrate, for some methods of measuring
exposure, a fairly consistent pattern of a small, increased risk with
increasing exposure that is somewhat weaker for chronic lymphocytic
leukemia than for childhood leukemia”.
