Numerical simulation studies regarding the workers’ radiofrequency exposure monitoring using wearable multi-location measurement system

The simulation study was to examine the effectiveness of reducing a discrepancy between parameters of unperturbed radiofrequency electromagnetic field (EMF) exposure in the work environment and results of workers exposure measurements using body-worn measurement systems, through performing simultaneous multi sensor (multilocation) measurements by sensors worn at various body locations and subsequent averaging of the results of such measurements.The obtained results revealed that the discrepancy in the outcome of EMF exposure assessments (the value of E-field strength normalized to the parameters of unperturbed E-field) coming from body-worn measurement system (delivering the parameters of EMF disturbed by the body of user wearing this system) may be significantly reduced by using a distributed (multilocation) measurement system.When using the three-point system with one of sensors on the helmet, the lowest discrepancy in the results of exposure evaluation using body-worn system is in case of location of other sensors on the chest and waist.
