In recent years non ionizing radiation has won particular importance in the academic, governmental, business world and also for the population in general. These radiations, in abbreviated form NIR, are radiation with frequency below UV and which do not have enough power to ionize materials. In this way, energy from radiation, absorbed by atoms and molecules is not enough sufficient to provoke the detachment of electrons from atoms, but may result in an increase in temperature of the tissue (thermal effect). Considering the complexity of this theme, the answer to the matter of the thermal effect, of interest to this work, comes from research and coordination of the most diverse areas, such as biology, medicine, and engineering, among others. Thus, the telecommunications engineering has a key role in clarifying population as regards radiation reference levels. This study aims to propose a model for evaluation of the transmitting stations of cellular mobile system and presents a theoretical modeling and the development of a computer simulation tool, for analysis of thermal effects caused by CEMRF generated by Radio Base Stations in multiplayer environments. Field measurements, with the purpose of analysis and verification of the functionality of the model are also presented and discussed in this work.
