Electromagnetic exposure assessment for telecommunication equipements using RF dosimeter

The correct evaluation of human exposure to electromagnetic fields is necessary in daily life because of the increase in RF devices and their proximity to the user. This assessment can be performed by using a personal dosimeter which measures the level of the electromagnetic field with the presence of the human body. The aim of this work is to present a correction law to reduce the measurements errors of a RF dosimeter due to the presence of the human body. To evaluate the performance of this law we used two errors: the Body Reflection Errors and Body Shadowing Errors. Two approaches combining electric and magnetic fields are studied in near and far field situations. Simulation results show that the application of the proposed correction law, which uses two diametrically opposite measuring point around the body, significantly reduces measurement error. Assessing the human exposure in near and far fields situations reassures users and especially the workers they are in an environment that respect the laws and standards of exposure to electromagnetic waves.
