29th November 2004
A synopsis of the day’s events
The new Electromagnetics and Health Laboratory at the University of Essex in
Colchester was launched on the 29th November 2004. The lab was officially opened
by Sir William Stewart, who is the Chairman of the National Radiological
Protection Board (NRPB) which recently released a new report on Mobile Phones
and Health. This review updates an earlier report published in 2000 by the UK
Independent Expert Group on Mobile Phones and Health, which was also chaired by
Sir William.
The launch of the laboratory was very successful with an opening address by
the Vice Chancellor of the University, Professor Ivor Crewe. Professor Crewe
introduced the work of the new lab as a truly multi-disciplinary project with
world-class experts in engineering, computer and biomedical science, behavioural
science and medicine working collaboratively to establish whether or not the
electromagnetic fields produced by mobile phone masts have an impact on the
health and well being in members of the general public.
The Director of the new lab, Professor Elaine Fox went on to describe how we
would go about studying this issue in more detail:
The study will test 132 people who report sensitivity to electromagnetic
fields (a condition often called "electromagnetic hypersensitivity" (EHS) as
well as 132 people who do not report any particular problems with
electromagnetic fields. Everyone taking part in the study will participate in 4
different sessions. The first session will allow the researchers to gather as
much information as possible from each person about the history of their illness
and what factors appear to make it worse. People will then be exposed to brief
periods of a GSM and a UMTS (3G) mobile phone mast signal and asked to report
any symptoms they experience. A wide variety of physiological and cognitive
measures will also be taken (e.g., blood pressure, heart-rate, memory,
concentration, etc…) during this session. The next 3 sessions will take place
around 1 week apart and will involve people being tested for approximately an
hour and a half in each session. During this period physiological functions will
be continuously monitored from small sensors place on the fingers of one hand;
cognitive functions will be assessed by simple tests of memory and
concentration, and people will also be asked to report any symptoms they
experience (e.g., headaches, fatigue, etc…) at any time during the session.
Each session will consist of just a single exposure which will either be sham
(i.e., the base station is not turned on), a GSM signal and a UMTS (3G) signal.
The order of the particular exposures will vary for each individual and neither
the participant nor the experimenter will know which exposure is being presented
in each session. This "double-blind" control is critical for scientific
validity. In order to ensure that any potential carry-over effects are minimised
and in consideration of the strain of testing on our participants, people will
be tested on four separate occasions at least one week apart.
The new Electromagnetics and Health Laboratory is a purpose-built suite of
fully electrically screened rooms provided by the National Physics Laboratory
that is designed to enable us to test what effects base station signals might
have on health and well-being in a well-controlled environment.

Professor Simon Saunders of Cellular Design Services Ltd (CDS) who designed
the exposure system then went on to talk about the technical aspects of the base
station signals:
He said that the role of CDS was to develop a system that closely resembled
the type of exposure likely to occur in the environs of a normal base station
(mast). The base station is to be housed in a specially designed room which will
allow participants in the research project to be tested under minutely
controlled conditions, to second and third generation (GSM and UMTS)
electromagnetic fields as might be experienced in the environs of a base
station.
The software supplied by CDS is critical to our study, because it is
responsible for not only guaranteeing that the signal emitted by the mobile
phone base station mimics those in the natural environment, but also guarantees
that the study is fully double blind (i.e. neither the experimenter nor the
participant know when the base station is ‘on’ or ‘off’) and the exact order of
the exposure conditions (GSM, UMTS, and Sham) are completely counter-balanced
across all of the participants. The reason why this is so important is so that
neither the experimenter nor the participant can influence the results of the
study. Furthermore, this design eliminates any potential order effects which
have been problematic in previous research in this area.
Sir William then declared the new lab officially open. In his speech he
congratulated the University of Essex on establishing a "unique
multidisciplinary laboratory". He said that this research will help
determine whether or not the electromagnetic fields produced by mobile phone
masts impact on the health and well-being of some members of the population. Put
simply---- can exposure to non-ionising radiation from mobile phone masts make
some people feel ill?
He also had this to say about the research into the potential health effects
of mobile phone masts:
"I have always been convinced that the way to find out the answers about
masts is to involve people directly… invite volunteers to participate in the
tests, carry out careful, well designed, scientifically robust studies
using reliable and proven techniques… and get straight to the point: are people
directly affected or not?"
The EMH lab is the only one of its kind in the UK and our hope is that the
results of this study will help to fill the gaps in current knowledge about the
possible negative health effects of mobile phone base stations under short-term
exposure conditions. Throughout our study we have consulted with various Action
and Support Groups and have had in-depth discussions with many individuals who
experience negative health effects from mobile phone technology. Alasdair
Phillips of PowerWatch felt that this was the "best facility of it’s kind that
he had seen" and was "excited about the results of the study". Now, with the
help of members from the general public we hope to gain a better understanding
of the effects of this mobile phone technology on measures of health and well
being.
