Description

The investigations examined the impact of the human body on the radiofrequency (RF) electromagnetic field (EMF) measurement results when using wearable, distributed (multi location), personal data loggers, compared with the unperturbed EMF values. The investigations covered numerical simulations mimicking various environmental exposure scenarios (frequency of 1.0-3.6 GHz, horizontal and vertical propagation of the EMF and E-field vector polarisation) corresponding to typical exposure conditions caused by wireless telecommunication systems. The preliminary results of these ongoing studies showed that the uncertainty of assessing EMF exposure (normalised to the parameters of unperturbed EMF) when using wearable RF EMF data loggers (delivering parameters of EMF disturbed by the body of the user wearing the data loggers) may be significantly reduced by using a distributed (multi-location) measurement system. The use of averaged results from at least three simultaneous measurements from wearable data loggers in various locations at the body may reduce the uncertainty approx. three-fold.
