Abstract— Mobile phone have become the most commonly used electronic gadget. A world without mobile phone is now almost unimaginable. The radiofrequency signals produced by mobile phones are transferred as electromagnetic radiation (EMR). EMR has the ability to penetrate through semi solid substances especially human body's tissues and caused dielectric heating. This effect can be classified as thermal and non thermal radiation. The skin near ear skull region is very thin compare to other part of human body. When using mobile phone for a longer period of time, this area absorbs EMR easily that can affects human immune systems. This paper is mainly focused on the study about signal absorption rate under various circumstances. Already there are various methods to measure this radiation rate, but International standard is not yet available. Here I measured the radiation power from the mobile phone and study has been done under various situations. Further work is being done on the measurement of SAR when mobile phones are used with headset and without headset. Index Terms— Radiation, Base station, SAR, Antenna, Radiated Power, Conical Log Spiral Antenna I. INTRODUCTION Cell phone technology has revolutionized the telecommunication scenario in India. Due to its several advantages, cell phone technology has grown exponentially in the last decade. Currently, there are more than 50 crore cell phone users and nearly 4.4 lakh cell phone towers to meet the communication demand. The numbers of cell phones and cell towers are increasing without giving due respect to its disadvantages. Because of this, scientists worldwide are concerned about the potential health risks associated with the use of mobile phones. As we all know, the radia... ... middle of paper ... ...d as IEEEC95.1-1991). Copyright1992 by the Institute of Electrical and Electronics Engineers, Inc.(IEEE), NewYork, N.Y.10017.

To start off, radiation from cell phones affect the activity of brain cells when it is held close to the side of the head. According to the article, “Cell Phones May Be Carcinogenic Hazards” by Danielle Dellorto, researchers have found that just after 50
In a world that is rapidly becoming faster paced, finding various means to keep up with the changing environment is a must. Cell phones are one of the most practical inventions of time that make this possible. However, the subtle effect they have on our culture today, their invasion of our privacy, and the possible health risks they may cause are reasons to reassess the value of this intriguing device. While cell phones may be valuable, they are also potentially harmful.

Cell phone technology dates all the way back to 1947. “In that year researchers first developed ideas as to the possibility of creating mobile phones that used "cells" that would identify a user in whatever specific region he or she was initiating the call from” (Cell Phone World). Still the technology was very limited at the time, so much more extensive research was required. In 1968 private companies started getting involved with cell phone development, such as AT&T. The FCC (The Federal Communications Commission) then opened new frequencies and the private companies had the theory of cellular towers. Each tower would be responsible for a particular region. When a customer traveled farther a way from one region it would switch the call to a closer tower with no interruption. In 1977 public cell phone testing had begun. People in Baltimore, Chicago, and Washington were the first to be eligible for cell phone trials. In 1979 a company in Japan began doing cell phone testing with the public. Not until 1983 were cell phones really available. “The year 1988 changed many of the technologies that had become standard in the past. The Cellular Technology Industry Association was created to set realistic goals for cellular phone providers and research new applications for cell phone development” (Cell Phone World). In a way they still were not very accessible to the public, due to their extremely high operating cost to the consumer. Only the very wealthy could afford cell phones. Important heads of cooperation’s, movie stars, and top government officials were able to afford the luxury of a mobile phone.
Cell phones have gradually become a large part of a person’s life. A person’s day usually starts and ends by using a phone. People may argue that this is false, but for many, their alarm is on their phone, and that is the first sound they hear in the morning, followed by the action of turning it off. Even looking at the time of day requires someone to turn on their phone. Even though a cell phone might be the most innovative item on the market that makes everyone’s lives easier, it could end up harming them from many different aspects. This paper will focus on scientific, economic, and environmental point of views.
It is undeniable that cellular technology has become main stream. “It was estimated that there were 92 million cell phone users in the US, a number growing by one million every month.” (Frumkin, Jacobson, Gansler & Thun 2001). The arrival and widespread use of cell phones has peaked interest of the health effects of radiofrequencies in the human body.

Cell phones have become a part of mainstream culture. Recently they have become more affordable and accomplish much more than making and receiving calls. Along with the growing popularity there is also growing concerns about safety and health. In this paper we will address cell phone history and how they have evolved. We will discuss health concerns such as tumors and talking while driving. Finally, we will talk about all of the technology that cell phones can accomplish such as receiving Email and buying stocks.

Cell phones are devices that emit radio frequency electromagnetic waves commonly referred to as RF-EMW (Brossner, Davoudi, and Kuber 19). Signals are transmitted through these waves from cellular devices to large antennas and centralized base stations (19). Studies show that excessive cell usage of four or more hours daily can affect male fertility greatly (19). The reproductive system of men is super sensitive and compartmentalized (19). Exposure to electromagnetic waves and currents may have some effect on count of sperm and motility (19). This is due to sperms electrically active cellular nature (19).
Every day of our lives, we watch as technology advances in leaps and bounds, so it was only logical when the cell phone came into existence, it would also be necessary to develop ways for a phone to be more than just a phone. With the explosion of the internet age people needed a way to bring their computers on the go, one that could fit in the palm of their hand. Whether it be checking emails, updating social networks or even playing games, smartphones seem to do it all. There is, however, a dark side to every technological advance that is made, to everything that makes our lives more convenient. Smartphones are not only an enormous distraction in our lives but are also known to cause health problems in those
The waves can be absorbed and reflected by surrounding objects before they reach the nearest cell tower. For example when you put your phone next to your head, during a...
