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. ...view middle of the document...
Tissues can get really harmed by radiation at high levels, cell death results and because of the amount of radiation being absorbed, cells cannot be replaced quickly and tissues fail to function. According to Isaac Tunez (University of Cordoba (Spain • Faculty of Medicine), fastest growing tissues are more venerable to radiation because radiation triples its effect during growth phase. Non-ionizing radiation has the energy to move atoms around a molecule or to make them vibrate, but not enough to remove charged particles such as electrons like how ionizing radiation can do. Since the radiation emitted from cell phones can’t break molecular bonds, then it cannot harm the DNA of the cells in the human body. Electromagnetic spectrum varies in size from the low modern use of radio communication the size of buildings to gamma radiation the size smaller than the size of the nucleus of an atom. There are three main types of ionizing radiation, the alpha rays, beta rays and the gamma rays. An alpha ray is very week and has a short range in air and cannot harm the outer layer of the skin. Beta rays are smaller particles but are stronger and more penetrating than the alpha rays. Gamma rays are the strongest and the most dangerous rays, these rays can pass through a body without hitting anything, or it may hit an atom giving its power to it. Cell phones emit radiofrequency energy, non-ionizing radiation. Radiofrequency is created because of the movement of the electrical charges in antennas. This is why phones give out this particular form of energy, radiofrequency energy. Radiofrequency energy has massive wavelengths; they are approximately the size of a football field. Cell phones are a two-way radio, which contains of a radio transmitter and a radio receiver. For example, when a person talks to another person through the use of their cell phones, then the voice of the person speaking on the cell phone will be changed into an electrical signal by his/her cell phone, then the signal is transmitted into via radio waves to the nearest cell phone tower. The network tower then transfers the radio waves to the other person’s cell phone, and that cell phone does the same. Both, cell phones and cell phone towers use radiofrequency to make and receive calls. The amount of radiofrequency energy used by a cell phone depends on:
1. The distance between the cell phone and the cell phone tower; that means the harder your phones works to get reception, the more radiation it emits.
2. The distance between the user and the cell phone’s antenna; the cell phones antenna transmits waves in all directions, therefore the waves can be absorbed and reflected by the surrounding materials before it reaches the cell phone tower. Therefore, when the cell phone put next to the head, the head absorbs the radiation.
3. The technology of the phone.
Radio waves pass through the human bodies all the time, from natural and unnatural sources, for example:
1. Ultraviolet rays
