A cell phone, also called a cellular phone, transmits electromagnetic radiation into the air. This happens when your cell phone needs to connect to a phone you want to have a conversation with, checking networks. Electromagnetic radiation, often abbreviated to EMR, is a form of energy that, when traveling through space, displays a wave like behavior. Electromagnetic radiation has electric and also magnetic field components. Electric fields are generated by electrically charged particles. The magnetic field is an area of ​​this force produced by moving electrical chargers. There are two types of electromagnetic radiation, ionizing radiation and non-ionizing radiation. Ionizing radiation is a type of radiation that has enough electromagnetic energy to remove electrons from tissue atoms and change the arrangement of the molecular structure. The two types of ionizing radiation are gamma rays, which are smaller than the nucleus of an atom, and x-rays, which are somewhat larger than gamma rays. Two types of frequencies are considered non-ionizing: radio frequency energy and microwave radiation. Then there is the electromagnetic spectrum which corresponds to the different frequencies of electromagnetic radiation, which ranges from extremely low frequency radiation to gamma rays. Frequencies are the number of times a wave moves up and down per second. At the bottom is an electromagnetic spectrum that explains the different types of radiation. Information on the dangers of using cell phones. How does it work? - (http://electronics.howstuffworks.com/cell-phone-radiation1.htm)Safe forms of energy shown in electromagnetic radiation are extremely low frequencies, very low frequencies...... middle of paper ... ...the new points are also explained in more detail by describing the images. The report contains information about the spectrum of electromagnetic radiation and whether waves are transmitted in any direction, the effects of absorption of electromagnetic radiation, why frequencies, wavelengths and particular output powers are used, etc. The report contains most of the performance criteria information and some merit criteria. My point of view is to be against the danger of using cell phones, because cell phones give off heat, which increases body temperature. Heat from cell phone screens can cause blindness and strain the eyes because the eyes do not have the function of dissipating excess heat. Mobile phone radiation heats the body, which can cause a kind of effect such as dehydration, because heating causes sweating, and excessive water loss causes dehydration..
