NN3 8PT
The Radiocommunications Agency (RA) is responsible for the management of the civil
radio spectrum in the UK.
The Government has asked the RA to implement a national
measurement programme to ensure that emissions from cellular base stations do not
exceed recommended guidelines.
RA engineers measure the power density of transmissions in the various radio bands to
be surveyed. The results, derived from electric field voltage measurements, are
referenced to and presented alongside the relevant International Commission on Non-
Ionizing Radiation Protection (ICNIRP) recommended non-occupational maximum
exposure levels.
On the left hand side of the results page(s) is a graphical
representation of the radio spectrum surveyed at each location on the site.
At the top
of each graph a red line indicates the ICNIRP recommended exposure level for that
frequency band. To the right hand side of each graph is a table showing the ten
highest level emissions recorded within a band. In addition to this report, results taken
from each audit site will be posted on the RA website at
www.radio.gov.uk
where
further information on the audit can be found.
Further explanation of the results and their context within ICNIRP guidelines can be
provided by the RA engineers at the time of the audit or by contacting the RA on 020
7211 0211 or by e-mail at rfaudit@ra.gsi.gov.uk.
The DfEE have issued advice and information about base stations to local education
authorities and schools in the DfEE's 'Spectrum' publication.
Further information and
contact points can also be found on the DfEE website at
http://www.dfee.gov.uk/a-

Report Summary
The Radiocommunications Agency performed this survey of the RF emission
environment prevailing in the vicinity of Blackthorn Middle School on 14 February
2001.
As the radio spectrum is continually changing, these measurements can only
provide information on the RF conditions for the specific location(s) at the time of
the survey.
It can be seen from this report that the highest value Total Band Exposure Quotient
was 1.458E-04 measured at location "Far corner of playing field". This value is
approximately 1/6859 of the ICNIRP maximum guideline reference level for public
exposure.
