Abstract—This paper talks about the growing concern in the people about the effect of mobile phone RF radiation on human brainwave signal using various techniques to capture those effects. Linear, Non- linear and statistical methods (t-tests) employed by various researchers to analyze variation in brainwaves.This paper gives comparison between brainwaves like Delta (0.5-4 Hz), Theta (4-8 Hz), Alpha (8-13 Hz), Beta (13-30 Hz) and Gamma (30 Hz-70Hz) in terms of Frequency Progressive map and amplitude progressive tri-maps. Electroencephalography (EEG) gives a noninvasive way of measuring brainwave activity from sensors placed on the scalp of the human head. So, the aim of this paper is to study the effect of RF exposure from mobile phone on Human brainwave as brainwaves Brain wave can provide information of mental state of the individual.

I. INTRODUCTION The use of mobile phone is increasing day by day around the globe, as cell phones have become an integral part of people’s lives. As per the world population clock the total world population is 7,012,000,000 and number of mobile users around the world are 6,800,000,000+ as evaluated in February 2013[1]. Thus, there are 97 phones per 100 citizens. Also India has second largest mobile users around the world with 937,055,980 mobile users from the population of 1,267,402,000. Thus,there are 73.9 mobile phone users per 100 citizens as per TRAI 30 November 2014 Press Release [2].Mobile communication device are used in immediate vicinity of the body, producing high localized RF energy deposition.Frequency band used for mobile are GSM900 or GSM 1800 or WCDMA 2100. Mobile phone emits pulsed high-frequency electromagnetic fields thatmay have some adverse effects on the brain activity and human health. Since mobilephones are used in closedproximity to human temporal region of head as shown in Fig. 1

In spite of using mobile phone below the permissible SAR level set by Health regulatory body (FCC, WHO,ICNIRP).TheFederalCommunications Commission (FCC) has set a SAR limit of 1.6 W/kg, averaged over a volume of 1 gram of tissue, for the head.In Europe, the limit is 2 W/kg, averaged over a volume of 10 grams of tissue. People encounter various symptoms like sleepiness, dizziness, headache, fatigue, loss of mental attention, heart palpitations, disturbance of digestive system, burning and tingling sensations in the skin of the head, memory loss, brain-tumours, decrease in sperm count, decrease in mobility and many more after the use of mobile phone. Still, there is no accepted evidences with which we can prove these effects are due to RF radiation. Thus, researcher are still finding way to prove the presence of such affects as there is also no proof that shows use of mobile phone is safe for use.Thus, it isnecessary to control the adverse effectscaused by mobilephone radiation on people. It is important to know that all humans brain display five different types of electrical patterns or brain waves across the cortex. The brain waves can be measured with an EEG (electroencephalograph) – a tool that allowsresearchers to record brain wave patterns. Each brainwave has a purpose and helps serve us in optimal mental functioning.Brain is considered to be important unit of central controlling system. As, the nervous system ofhuman is divided into three main system i.e. 164
