Mobile communication has played a vital role in being a progressive tool of Information Technology. In the race to adopt new technologies, we often ignore the side effects of technology and do not realize the repercussions. The scientific evidences do not clearly support the risk of electromagnetic radiations (EMRs) from communication devices to a significant level. However some innovators are urging parents to reconsider the effects of mobile phones before giving it to the young generation. Mobile phones radiate EMRs an average power of 0.2 to 0.6 watts when hand-held and operated close to the head and approx. 40-50% of radiated energy is being absorbed into the brain. Although several countries have initiated R&D to investigate the possible side effects of mobile phones but hardly handful of them make a significant impact. This Book contains discussion on risk of electromagnetic hypersensitivity (EHS) and research analysis regarding self reported symptoms and sensations. The book can be beneficial for research students to understand Green Communication approaches about suggestive safety measures and using patterns.
