The Stewart Report

The Radiocommunications Agency (RA) is responsible for the management of the civil radio spectrum. As part of that function the RA helps prevent interference to radio services and also measures radio emissions.

The Stewart group was set up to examine public health concerns about mobile phone emissions. The Stewart Report (Independent Expert Group on Mobile Phones) said that there was no evidence to conclude that there was any risk to public health from mobile phone base station emissions as exposures are expected to be a small fraction of the guidelines. Nevertheless, the Report said that as part of it’s recommended precautionary approach there should be an independent audit of base stations.

In response to the report’s recommendation the Government asked the RA to implement a national measurement programme to ensure that emissions from base stations do not exceed guidelines.

The Audit

Through 2002 the RA continued with a programme of audits. The 2002 programme concentrated on schools near to masts and hospitals. The aim of the audit programme was to ensure that emissions from mobile phone base stations were below the International Commission on Non-Ionizing Radiation Protection (ICNIRP) guidelines.

A total of 109 audits of schools and hospitals were recorded for the year 2002. There are however 110 audits listed below. This is due to the final audit being carried out, and dated, at the end of 2002 but not being processed until January 2003.

A summary of the highest measurement at each school and hospital site is shown below. Detailed results of each survey can be found by clicking on the name of each individual site. The audit recorded levels typically many thousands of times below the ICNIRP guidelines, with the lowest recorded level 1/19907515 and the highest level 1/731 of the guidelines.

It should be noted that 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.

Glossary

Antenna Antenna - The antenna device connected to the receiver. This is known by its serial number, type and manufacturer, and has an associated calibration.
Band Exposure Quotient The sum of the frequency exposure quotients of a band at a location.
Calibration A set of frequency (Hz) and K-factor (dB) pairs that define the gain characteristics of the antenna. Linear interpolation is used to obtain K-factor values for intermediate frequencies.
ETACS Extended Total Access Communications System
Exposure This is the name given to the measured results. The maximum electric field strength values in dB microvolts per meter are converted to power density in watts per square metre.
Frequency Exposure Quotient This is the ratio of the measured maximum electromagnetic power density to the ICNIRP limit at a given frequency. A value close to 1 signifies that exposure levels could be near to the maximum permitted at that frequency.

ICNIRP Limit This is a guideline for the maximum permitted power density of non-ionizing radiation for public exposure. The reference level is frequency dependent and is currently defined as:
Frequency ICNIRP Limit
Less than 400MHz 2 W/m2
400MHz to 2GHz (f/200 W/m2), where f is frequency in MHz
2GHz to 300GHz 10 W/m2
Location The point at which the readings are taken. Each location is uniquely identified by its NGR co-ordinate and its timestamp. A description of the location should be sufficient to allow the position to be identified at a later date.
NGR The co-ordinates of the location. In this survey they must be specified using a 100km tile identifier followed by a 4-digit easting and northing as defined in the Ordnance Survey National Grid Reference (NGR) system. N.B. This gives the position of a location to 10 meter precision e.g. TQ 3056 2184
Power Density The energy flowing from an antenna through a unit area normal to the direction of propagation in a unit time. This is measured in watts per square meter (W/m2 ).
Start Time The date and time at which the receiver started taking its measurements at a location.
Sweep Band The measurements are taken at regular frequency intervals within a band of frequencies. A sweep band is defined by the band title (which appears on each graph), start frequency, end frequency, frequency step, bandwidth, & dwell time.
Table Data The "Maximum Exposure" column consists of the ten highest exposure values in a band. Accompanying them are the frequency at which the maxima occurred, the ICNIRP Limit at that frequency, and the frequency exposure quotient.
TETRA Terrestrial Trunked Radio
Total Band Exposure Quotient The sum of the frequency exposure quotients of all the bands at a single location.
