A cell phone is a cellular device that can receive and make calls through radio link while being in any part of the world, as long as there is cellular network.
• EME is electromagnetic energy also known as electromagnetic radiation (EMR) that we are surrounded by every day, emitted from natural sources like the sun, earth and the ionosphere. It is also emitted from unnatural sources like mobile phone base stations, broadcast towers, radar equipment, remote controls, electrical and electronic equipment. Electromagnetic radiation travels in waves. There are many types of electromagnetic waves which differ in the wavelength. These electromagnetic radiations form the electromagnetic spectrum. Electromagnetic spectrum is the range of all the possible frequencies of electromagnetic radiation. Frequency is the number of waves travelling per second. Electromagnetic waves are produced by the movement of electrically charged particles (ions), which are atoms that gain or lose particles. These waves travel through air, empty space and other substances. This radiation that is given of radioactive materials such as x-ray machines, nuclear reactions and ultraviolet rays are all examples of ionizing radiation. This energy kicks out electrons from molecules with which they interact, thus creating ions. Radiofrequency radiation is at the low end of the electromagnetic spectrum, this energy is a type of non-ionizing radiation. Some of the ultraviolet rays that are emitted from the sun are considered as ionizing radiation, ultraviolet rays can harm humans. Ultraviolet rays are important to humans for gaining vitamin D in the body, but too much of it can cause sun burns and in a lot of cases, skin cancer. So the skin tissue is damaged, so the DNA...

...w that cell phones do not cause cancer. Scientists need to make further investigations if cell phones really are dangerous. In most cancer and health care websites, they prevent too much use of cell phones for example, the Cancer Research UK and the World Health Organisation.
Newspaper and magazine articles can be bias but the newspapers and magazine articles that were researched and were given above were not very biased information because most of them were health care websites.
The internet was used to give information on topics like EMR, RF energy, EMS and more. The websites that I used to find out general information from the internet was from organisations and reliable websites. The internet was also used to give information from studies that were taken place, however, the studies were taken from cancer and research related websites (e.g., Cancer Research UK).
Just whip out your handy dandy cellular device and now you don’t have to talk to anyone! Cell phones are perfect for avoiding those awkward conversations, weird situations, they can even find you a spouse while at the same time help our population decrease, creating more jobs and space in the world! Everyone gets stuck in situations where they feel awkward; whether it’s on a bus, in the mall, walking down the street, or even driving; a cell phone is the only solution to solving these problems. Cell phones make it easy to block out the world surrounding you.
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.
When cell phones were first introduced, all you could do was call others and talk for half an hour. It was like a brick and took ten hours to charge. It also cost $3995. That’s a lot more than most of today’s cell phones. Even, though it was a very basic phone, it began impacting the world. Now, you could call your relatives and actually talk with them without being next to them. Parents gave their kids cell phones to stay in touch. Now you can contact anyone through your mobile phone in multiple ways. You can text, call, facetime or message someone through social media. Cell phones abilities
They give us the freedom to contact people anywhere at any time. If there is a sudden change of plans, people can contact one another by texting a quick short sentence in a matter of seconds. Cell phones act as first responders at a scene when someone is hurt and needs help. New-aged cell phones are programed with a built in tracking device that can be used to locate a kidnapped victim, stolen car, or purse.
Cellular phones are a phenomenon that has engulfed people in the nineties. They have become a common occurrence whether you are waiting in line at the super market or in a movie theatre. One professor at Murray State University said, “Many students are carrying them, I had a student get a call in the middle of a test last semester.” Although many people have accepted the thought of carrying a telephone wherever they go, others have not taken the onslaught of cell phones quite so easily. Cell phones have become part of everyday life, and with the dramatic changes that have been made, there is no sign of their existence diminishing. Today, cellular service is available in all 306 Metropolitan Statistical Areas across the country and all of the 428 Rural Service Areas.
Cell phones use radio frequencies to transmit signals. Radio Frequencies (RF) are a form of electrical waves similar to those used in radios, microwaves, radars or satellite stations. They are emitted from a transmitter, and received using an antenna. This telephony technology is restricted geographically to small zones called “Cells”. Every cell has a base station capable of sending and receiving radio waves. When a call is started a signal leaves the handheld unit headed to the closest base station. This station answers by allocating a specific channel to the unit. When this “channel” is established, modulated radio frequency signals are both received and transmitted. The head of the user is in the near field of use because the distance from the antenna to the head is a few centimeters. (Blettner & Berg 2000) If the antenna is inside the body of the phone, the exposure to Radio Frequencies is greater. The antenna might be requesting a stronger signal to contest with the interference of the battery or the actual shell of the phone’s body.

Brain tumors and eye cancer are two health concerns of cell phones that are currently under investigation. Many people have heard rumors about whether or not cell phones are responsible for these health problems, but answers never seem to be found.
Scientists and engineers have been able to enhance our lifestyles by understanding and using the Laws, Concepts and Principles of Optics and how they are applied in Optical Instruments. The key concepts are:
Research also points to an increased risk of multiple types of cancer (Hardell 40). Epidemiologic evidence in the last few years claims that mobile phone usage and risks of brain tumors and other types, such as salivary gland tumors in the adult head have grown tremendously
First of all, using mobile phone has the negative effect of affecting the health. The scientific data are exploring the relationship between radiation from mobile phones and brain disease. "Research carried out by scientists in Finland suggests radiation from mobile phones causes changes in the brain. It is the first time that scientists have looked at the effects of mobile phone radiation on human cells rather than those of rats"(BBC NEWS, 19 Jun 02 | Health, "Fresh fears over mobile phones"). From above we must understand that research did find a higher incidence of brain tumors on the same side as phone usage.
Twenty-five years ago, a phone was just a way to contact someone. Mobile phones have become one of the most common tools of communication for both young and old. Cellular devices have redefined relationships and social conduct, and transformed the daily lives of many individuals. Cell phones no longer function just as a communication device. Today it has many other uses.
A mobile phone is a telephone that can make and receive calls over a radio
Scientists also say that cell phones don’t cause cancerous diseases well my opinion is that we should reduce the time we spend on our cell phones, don’t be on it all the time and try to slowly avoid cell phones and use handsets.
The volume of the information that you will find on the internet is outstanding. For every topic that pops in your mind, then you will sure be able to find it on the internet, because there is always someone that has written about it. The internet can offer you a series of different perspectives on a single topic. As a matter of fact, you can even connect to an online encyclopedia.
