This report describes laboratory testing and volunteer trials to evaluate a personal exposure meter (PEM) developed to measure exposure of the general public to radiofrequency radiation, as from telecommunications base stations, broadcast transmitters, and personal use of mobile phones. The PEM is designed to measure the electric field strengths of radio signals in several different frequency bands where there are known to be transmitters that contribute significantly to public exposure.
The laboratory tests showed the PEM had performance broadly in line with its intended purpose, however there were several issues requiring further attention. For example, it could not measure signals from TETRA base stations, wireless computer networks and digital cordless phones but these capabilities could be added.
Recommendations have been made that should improve the usefulness of the PEM for validating exposure modelling techniques and as a monitor to assess radiofrequency exposure.
