Assessment of personal exposure to wireless communication technologies in different microenvironments

The use of mobile communication applications, services, and technologies has become an indispensable part of everyday life, a fact which has promoted research on the assessment of human exposure to radio-frequency electromagnetic fields and related health issues. To evaluate personal exposure to wireless technologies and broadcast transmitters in this study the personal exposure meters with tri-axial E-field probe are used, enabling frequency selective measurements of electric field strength in 14 predefined frequency bands (80 MHz-6 GHz). The measurements were conducted in five microenvironments: home, office, coffee shops, transport vehicles and outdoor, resulting in 122 944 measurement samples. For each microenvironment the mean value of power density from different wireless technologies is presented, including the contribution of specific wireless technology to the total personal exposure. The obtained results are compared with the exposure limits given by the International Commission on Non-Ionizing Radiation Protection.
