A microdosimetric study at the cellular and intracellular level using a 3D realistic cell model

Radio frequency electromagnetic fields (RF EMFs) are increasingly used in emerging telecommunication technologies such as wireless power transfer (WPT), 5G millimetre-wave (mmWave) technologies, with a public concern regarding their environmental safety. Microdosimetric investigations provide an insight into the local distribution of the electric field induced at the level of cellular and sub-cellular structures exposed to RF EMFs. The aim of this work is to provide a quantitative evaluation of the EMFs in cells, using a 3D microdosimetric model with a realistic shape of the cells and intracellular organelles (i.e. endoplasmic reticulum and nucleus). Results are presented in terms of local electric field distribution, local volumetric power loss density distribution and transmembrane potential induced on the cellular and sub-cellular membranes, with a focus on the comparison between EMFs exposure at 700 MHz, 3.7 GHz and 60 GHz.
