“…The exposure due to radiations from towers or other gadgets is on whole body whereas that from the mobile phone handset is a kind of local exposure [1] and is very near to our brain, thus, is a matter of concern. Thermal radiations from the mobile phone is quantified by the specific absorption rate (SAR) value which causes heating of the tissues that increases with the duration of the mobile usage [2]. In view of public and governmental concern, World Health Organization established the International Electromagnetic Fields (EMF) in 1996 to assess the adverse effects of these fields.…”

The experimental study of electromagnetic interference of mobile phone radiations on brain waves is a contemporary research area and the ever-increasing use of mobile phones make it more imperative to explore the problem area in detail. Electromagnetic signal from mobile phones operating in Global System for Mobile (GSM) and wide band code division multiple access (WCDMA), has been considered in this paper and their interference impacts have been analyzed on the human electroencephalogram (EEG). The impact on brain waves i.e., delta, theta, alpha, beta and gamma waves are analyzed in five modes namely ideal mode i.e., when mobile phone is not in use, transmission mode and the receiving modes of second generation (2G) and third generation (3G) networks. The data has been acquired from 75 young and healthy students of a post graduate institute while the students were making their routine calls. The acquired EEG signal is analyzed using various parameters viz.; Approximate Entropy(ApEn), Largest Lyapunov Exponent (LLE), Hurst Exponent (HE), Correlation dimension (CD) and the power of the brain waves have also been analyzed. It has been found that due to mobile phone usage, there is variation in the nonlinear parameters and increase in the power of the alpha brain waves at T5O1 during 3GRx and decrease in alpha power at the P4O2 channel in all modes. It has been observed that the change at the right temporal region is more, the side to which mobile phone was held. The Statistical analysis has also been done using SPSS software which shows significant variations at some of the channels in different modes.

“…(Maeso, 2001) durante las últimas décadas, el número de antenas de estaciones base de telefonía móvil que emiten radiación electromagnética (REM) de radiofrecuencia (RF) han aumentado significativamente (Buckus et al, 2017). El uso de esta tecnología aumenta la preocupación sobre los posibles efectos de la REM generada y sus posibles efectos sobre la salud del público en general (Lahham, Alkbash, & ALMasri, 2016) ya que las RF utilizadas en la comunicación móvil tienen la capacidad de penetrar a través de sustancias semisólidas como la carne y tejido vivo (Mat, D. A. A., 2010) Las actividades realizadas en ubicaciones cercanas a estaciones base implican la exposición del público a las ondas de radio.…”

Esta investigación permite dar a conocer los riesgos físicos en las tareas de mantenimiento de una estación de radio base de telefonía celular. A pesar de que hasta la fecha las investigaciones realizadas anteriormente no presentan evidencia científica importante para indicar que estas radiaciones afectan al ser humano, estos análisis han determinado la existencia de límites de exposición a radiaciones no ionizantes, los cuales deben ser respetados por los trabajadores que realizan este tipo de trabajos. Las mediciones de densidad de potencia (s), densidad de campo eléctrico (e), densidad de campo magnético (H) realizadas para alturas (h) de 2 hasta 5 m en el lóbulo principal del emisor o antena donde existe la máxima ganancia determinaron un 32 % de los puntos medidos sobrepasan el límite permisible. Con estos valores se establecieron las distancias de seguridad y, por lo tanto, se determinó que: la altitud es inversamente proporcional a la densidad de campo magnético, eléctrico y de potencia.

“…Non-communication sources of RF energy include microwave ovens, radar, and industrial uses. The complete electromagnetic spectrum consists of both ionizing and non-ionizing radiation [1]. Non-ionizing radiation does not carry enough energy to remove an electron from an atom or a molecule.Sources of non-ionizing radiation include microwaves, radio waves, cordless phones, wireless networks (wi-fi), power lines and MRIs [3].…”

Delinquency of 4G communication on Human Health

4G communication is the visionary communication technology. It promises up to 1 Gbps of speed and will be a packet based network. Because of high speed our most of the applications will go wireless and average contact hours of an individual will be significantly increased. 4G works on higher band of frequency. The concern has been raised about the possibility that exposure to the radiofrequency (RF) fields from 4G user terminals or their base stations could affect people's health. Higher functionality handsets deliver more SAR and higher bracket of frequency add up possibly more risk. The WHO has classified mobile phone radiation on the IARC scale into Group 2B -possibly carcinogenic. This work demonstrates findings on this aspect and a detailed survey has been done and possible ways to reduce health risk are proposed.
