Modelling of neuronal cells exposed to RF fields from mobile telecommunication equipment

The problem of studying the interaction between electromagnetic fields and biological systems can be approached from both theoretical and experimental points of view. In this work, a theoretical model based on experimental re sults has been introduced in order to study the exposure of neuronal cells to radio frequency (RF) fields. The model proposed is based on linking toge ther two different levels of the biological scale, the level of the single ionic channel of the membrane and the level of the whole cellular membrane. Specific electromagnetic signals have been considered: in particular pulse d signals and continuous wave signals. Results have shown that the effect o f the electromagnetic exposure can be regarded as a variation from the phys iological situation of less than 6%. (C) 1998 Elsevier Science S.A.
