This article determines the whole-body Specific Absorption Rate (SAR) in the GSM 1900 frequency band, using the Duke virtual family model and Sim4Life software, in order to evaluate the electromagnetic exposure in the ESPOCH premises. Initially, 128 measurement nodes were delimited using Google Earth software and, at each node, spatial measurements of the electric field were taken at 14 points distributed on the Duke model, using Narda SRM-3006 equipment at a frequency of 1967.5 MHz, with an exposure time of 6 min for each point, complying with ICNIRP regulations. Subsequently, the quadratic mean of the 14 points in each of the 128 nodes was obtained. The root mean square values were stored and processed in a database for the calculation of whole-body SAR. The results obtained show minimum and maximum SAR values of \(9.76 \times 10^{-10}\) W/kg and \(3.9 \times 10^{-7}\) W/kg, respectively, which are well below the permissible exposure limit of national and international regulations of 0.08 W/kg. Finally, with the SAR values, we proceeded to perform electromagnetic mapping in the ESPOCH premises, which allows a clearer visualization of the whole-body SAR values, highlighting the areas with the highest concentration of radiation by means of a color map.

摘要

This article determines the whole-body Specific Absorption Rate (SAR) in the GSM 1900 frequency band, using the Duke virtual family model and Sim4Life software, in order to evaluate the electromagnetic exposure in the ESPOCH premises. Initially, 128 measurement nodes were delimited using Google Earth software and, at each node, spatial measurements of the electric field were taken at 14 points distributed on the Duke model, using Narda SRM-3006 equipment at a frequency of 1967.5 MHz, with an exposure time of 6 min for each point, complying with ICNIRP regulations. Subsequently, the quadratic mean of the 14 points in each of the 128 nodes was obtained. The root mean square values were stored and processed in a database for the calculation of whole-body SAR. The results obtained show minimum and maximum SAR values of \(9.76 \times 10^{-10}\) W/kg and \(3.9 \times 10^{-7}\) W/kg, respectively, which are well below the permissible exposure limit of national and international regulations of 0.08 W/kg. Finally, with the SAR values, we proceeded to perform electromagnetic mapping in the ESPOCH premises, which allows a clearer visualization of the whole-body SAR values, highlighting the areas with the highest concentration of radiation by means of a color map.
