Evaluation of non-ionizing radiations from the Wi-Fi network at the University of San Marcos

Abstract

This study was to evaluate the non-ionizing radiations (NIR) from Wi-Fi systems at the new building of the Faculty of Electronic and Electrical Engineering (FIEE) – University of San Marcos (UNMSM). To perform the scientific literature review on health effects from Wi-Fi networks they were considered the most important releases from 2009 to 2013. It was then performed a revision of technical standards for Wi-Fi networks. It was designed and implemented a trial network to generate Wi-Fi signals used to carried out the measurements of NIR in a semi –controlled environment. In order to assess non-ionizing radiations from access points of Wi-fi networks it was used un electromagnetic field analizer Narda NBM 550 and there were carried out two types of measurements, one with an isotropic probe EF 0691 from 100 kHz to 6 GHz and the other with an isotropic probe ED 5091 to provide the exposure quotient from 300 kHz to 50 GHz, ICNIRP Ocupacional Standard 1998. In the review on health effects, the studies confirmed that the only effects at these frequencies are related to tissue heating and in case of Wi-Fi systems the temperatura increase produced by NIR is very small so they could only produce biological effects but not health effects.
