Integrated models for the analysis of biological effects of EM fields usedfor mobile communications

The understanding of the modalities of interaction of electromagnetic (Ehl) fields with biological material is a key point in the identification of po ssible induced effects. Since the beginnings of bioelectromagnetic research studies, most of the attention has been focused on the effects on nervous systems and neuronal cells. The importance of this target has recently incr eased due to the wide diffusion of mobile terminals, used close to the head . In this paper, an integrated interaction model is proposed, The model, va lidated in each part of its components with experimental data, allows to ob tain a quantitative link from the external applied field to the effects on neurons (isolated or linked to similar others), The models is firstly based on the evaluation of the EM field at cellular membrane level, then on the evaluation of the effects induced on each component of the model growing fr om the low biophysical level (membrane channels) to the biological one (neu ron time behavior). The use of well-assessed models for the simulations of each part allows both the evaluation of the effect at different levels of c omplexity, and the employment of this effect acting as an input on the uppe r level, This approach allows, for the first time, a complete quantitative evaluation of the effects on neurons due to the fields from the existing mo bile systems, and can be a useful instrument for the evaluation of the poss ible health impact of new technologies.
