Two interlaboratory comparison programs on EMF measurements performed in Greece

This paper presents two interlaboratory comparison schemes on electromagnetic field measurements. The first scheme involves measurements of the electric field produced by a scale transmission line and of the magnetic field produced by a medium voltage cable, whereas the second scheme involves measurements of the high frequency electromagnetic fields level and calculation of the total exposure ratio in the vicinity of mobile phone base stations and antennas transmitting in the radio and TV frequency bands. The measurements procedure and the calculation of the performance statistics z scores are analyzed for both schemes. Emphasis is given to the evaluation of the results, in order to investigate possible improvements on the overall implementation of the schemes and error factors related to the equipment and the measurement procedures of the participants.
