A cell phone is a mobile device that can receive and make calls through radio link while being in any part of the Earth, so long as there is cellular network. • EME is energy also known as electromagnetic radiation (EMR) that we are surrounded by every day, emitted from organic sources such as sunlight, earth and the ionosphere. It is also emitted from unnatural sources such as cell 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 vary in the wavelength. These electromagnetic radiations form the electromagnetic spectrum. Electromagnetic spectrum is the range of all the probable frequencies of electromagnetic radiation. Frequency is the number of waves travelling per second. Electromagnetic waves are created by the movement of electrically charged particles (ions), which are atoms that benefit or shed particles. These waves traveling through air, empty space and other substances. This radiation that's given of radioactive materials like x-ray machines, nuclear reactions and ultraviolet rays are examples of ionizing radiation. This energy kicks electrons out of molecules with which they interact, thereby creating ions. Radiofrequency radiation is at the very low end of the electromagnetic spectrum, so this energy is a kind of non-ionizing radiation. Some of these ultraviolet rays which are emitted from the sun are regarded as ionizing radiation, ultraviolet rays can damage people. Ultraviolet rays are important to humans for gaining vitamin D within the body, but too much of it may cause sun burns off and in a lot of instances, cancer. So the skin tissue is damaged, so the DNA...
