Desarrollo de un modelo computacional utilizando el simulador Sim4Life para obtener la distribución de la SAR en el cuerpo humano producida por los campos eléctricos de las antenas transmisoras de radio, televisión y estaciones base de celulares en diferentes escenarios cercanos a las antenas transmisoras de celulares.

Abstract

A computer model was developed using a Graphical User Interphace (GUI) of MATLAB that allows calculating the Specific Absorption Rate (SAR) under conditions of spatial exposure to non-ionizing radiation. It has been based on the Computable Assisted Designer (CAD) models of the Virtual Family V3.0: Duke, Ella, Billie and Thelonious. Some measurements of the maximum and average intensity of the electric field were taken from the telecommunications services such as radio, television, and mobile phones in ten different scenarios that are close to antennas in different places of Riobamba. This was done using the models Duke, Ella, Billie and Thelonious in 18 points in the human body considering the spatial exposure of the electric field to do the simulation of the SAR with values of maximum and average electric fields in a generic scenario for each model in this frequency band: from 76 MHz to 2.6 GHz. When doing the comparison of the measured values in the 10 different scenarios to the ones established with the International Commission on Non-Ionizing Radiation Protection (ICNIRP) it could be determined that the radiations are under the maximum allowed by the ICNIRP in these scenarios. When comparing the results of the simulations to the ones calculated by the computer model, a minimum margin of error of the SAR value was determined. This demonstrated that the model is satisfactory for the maximum intensity as well as the average intensity of the electric field. This computer model will be useful for assessing the levels of electromagnetic radiation and/or epidemiologic studies. It is recommended to do intensity measurements of the electric field under other traffic conditions and other characteristics of the scenarios in order to verify which levels of non-ionizing radiations are considered within the norms fixed by the ICNIRP.
