Bourne: Tetra - the case for control
The Conservative
Speech to the National Assembly for
"Tetra, or terrestrial trunked radio, the
digital cell phone system that the Government has chosen for the
police, has been causing anxieties since the masts started to be
erected to support the system in 2001.
Tetra, like mobile phone systems, uses masts or
base stations. The advantages of the system for the police are well
known.
The system offers the user fairly secure
communications that, like all other digital radio technologies, deliver
clear speech. It allows users to talk in a group with radios, and to
talk to other users with similar digital systems elsewhere.
It has a help button that enables the user to
call for assistance very quickly. Other
facilities, such as the ability to look up police computer information,
are said to be possible in the future.
Without doubt, there are many advantages to the
system. However, there are also associated potential health risks
related to the signal strength and associated electromagnetic fields.
Tetra technology has not been tested to
ascertain whether it is safe over the medium or long term. It is a
microwave system, like ordinary mobile phones, but the masts talk to
each other directly, and, unlike mobile phone masts, they transmit 24
hours a day.
Signals are sent in pulses or bursts, which are
transmitted at a frequency that coincides with the electrical frequency
of the human brain in its waking state. Its amplitude is modulated at a
rate of 17.65 Hz, very close to the beta waves of the human brain,
which pulse at 16 Hz. It has the potential to interfere with, and
overwhelm, normal bodily functions.
This may sound terribly Dr Who, but systems
that pulse at a similar frequency to Tetra were investigated for their
potential as non-lethal weapons by the
Tetra has been known to have an effect on
pacemakers, baby alarms, medical equipment—including first aid
heart defibrillators—and vehicle electronics.
I know that Assembly Members from all parties
have some of these concerns.
Although much research has to be done on the
siting of masts, the potential risk cannot be ignored, and must be
factored in to any consideration on the siting of the masts.
It is the issue that is of primary concern to
me in this debate. At the moment, the stringent planning conditions
that apply to other forms of construction do not apply to Tetra phone
masts.
Assembly planning guidance Technical Advice
Note 19 sets out guidance on the siting of the masts and the specific
situations where planning permission is not needed.
One of these exemptions is where the height of
the mast is less than 15m. Importantly, this also applies where such a
mast is placed on top of an existing building.
This loophole, as I see it, has recently been
exposed by a case in Haverfordwest. I have had a great deal of
correspondence on the matter, as have other Assembly Members.
I am sure that some other suitable location
could be found for this Tetra mast. It should not be sited on top of a
police station in the centre of a busy town.
The police station is right in the centre of
Haverfordwest, in probably the most densely populated area in the
county, and is in close proximity to eight schools, seven of which are
primary schools, and one of which is a special needs school.
Parents and concerned residents in the town are
campaigning hard for the removal of the mast, and I strongly support
them, as do others.
Stephen Crabb, the MP for Preseli
Pembrokeshire, with whom I am working closely on the issue, told me
that Tetra has been the biggest single component of his mail bag since
he was elected in early May—such is the concern about the
issue.
We have both written, as I know have others, to
the managing director of O2 Airwaves, which is responsible for the
mast, asking for it to be moved or turned off until such a time as it
can be agreed that the mast be sited elsewhere.
Unfortunately, this request did not get very
far, to say the least.
It is fair to say that there is no illegality
involved. Local authorities and the company have complied with the law.
They are following Assembly Government
guidance, clearly illustrated in a letter that I received in May from
Pembrokeshire County Council, which said that if the telecommunications
equipment complies with International Commission for Non-ionising
Radiation Protection guidelines on power emissions, it should not be
necessary for a local planning authority, in processing an application
for planning permission or prior approval, to consider further health
aspects and concerns about them.
In my opinion, that is totally
wrong—not legally, but in terms of common sense and morality.
Masts under 15m should be subject to the same
planning considerations as those above that height, but, in all cases,
I am keen to see a change in the planning system so that proper account
is taken of health considerations at the planning stage, which does not
happen at the moment.
The lack of public consultation is naturally a
major cause of grievance in people who suffer a loss of amenity when
masts are erected without adequate consultation.
I consider, as do others, the current situation
to be unacceptable. This is, of course, not only a matter of health
risks. There is the problem that the siting of base stations,
particularly masts, can result in a loss of amenity and almost
certainly a reduction in the value of property.
Furthermore, the frustrations and concerns have
a negative effect on people's health and wellbeing.
A mapping exercise should be undertaken in each
local authority area to ascertain the most appropriate sites for masts
away from residential developments, like Usmeston on the outskirsts of
Haverfordwest, which is being considered and has been the subject of
unsuccessful applications in the past.
They should certainly be sited away from
schools, but schools in Haverfordwest are affected by the mast on the
police station. I know that that has been a concern elsewhere in
Stewart conducted a review of the position on
mobile and Tetra masts, and I strongly support many of the findings.
For example, it recommended that a national register of base stations
should be established.
I am pleased that, in the wake of that report,
we now have a site-finder system so that it is easier for the public to
access information about the location of base stations.
Such resources are excellent, but they are only
one part of the issue. It is ludicrous, as I said, that masts shorter
than 15m, particularly when they are on top of existing buildings, do
not require planning consent; that should be a requirement.
Basically, we need a far more robust planning
framework that incorporates an input by health authorities and local
health boards and a clear and open system of documentation that can be
readily inspected by the general public.
Transparency is paramount.
The evidence amassed over time suggests that
children in particular, hence the significance of the schools issue,
might be especially vulnerable to any adverse effects of radio
frequency radiation.
On the frequencies used in mobile-phone
technology and Tetra, there is strong evidence that children absorb
more energy per kilogram of body weight than do adults.
As Stewart points out in the review, a
one-year-old could absorb around double that a mature adult could, and
a five-year-old, around 60 per cent more.
Additionally, since children are being exposed
to radio frequency radiation from base stations from a younger age than
adults, over a longer time they risk accumulating more exposure than us
over the course of their lives because this technology is new.
The case for keeping these masts away from
schools is massive. Stewart argued for a precautionary approach.
Such is the concern that many countries have
prohibited the placement of base stations near schools, and we should
do more to echo that approach.
We need to adopt a precautionary approach to
Tetra masts in
The advantages of Tetra may be great, and I am
sure that they are, but we cannot go on as we have been going. I hope
that this debate will focus attention on those key issues.
However, I will summarise my conclusions and
ask the Minister to address them specifically. All masts should require
planning consent from the local authority.
I know that that is not currently the case, but
they should require consent, whatever their height. The planning
process must consider potential health hazards of masts.
No masts should be situated close to schools. A
mapping exercise should be undertaken in each case to locate the best
possible site for the mast in a given area.
The process must incorporate an element of
public consultation in all cases, and there should be a continuing
review of the medium and long-term health risks of Tetra masts. That is
the case for the control of Tetra."
