What Is Radiation?
In general, radiation is a process where energetic waves or energetic particles emitted by a source in form of rays or waves travels through some materials or space. For example, sound waves move from a speaker’s mouth to a listener’s ears, or heat waves goes from the Sun to the Earth. Natural radiation resources are present in cosmetic rays from outer space, in soil, water, and vegetation; human body also contains radioactive elements in carbon, lead, and potassium. Man-made radiation resources are X-rays, radiation therapy, fuel cycle, nuclear power plants, etc….
Radiation is commonly classified in two types: ionizing and non-ionizing radiation. In article .. “ionizing radiation has enough energy to detach electrons from atoms or molecules – the process of ionizing.” This report refers to non-ionizing radiation, any type of electromagnetic radiation and relatively low-energy radiation. Non-ionizing only has enough energy to cause chemical change, heating change, and other molecular changes.

Non-ionizing Radiation:
Non-ionizing radiation does not produce charged ions when passing through matter, is “a series of energy waves composed of oscillating electric and magnetic fields traveling at the speed of light (Non-Ionizing Radiation). Non-ionizing radiation is divided   to:
• Extremely Low Frequency Radiation:   is produced by power lines, electrical wiring, and electrical equipment.
• Radiofrequency and Microwave Radiation: while Radiofrequency radiation may be absorbed throughout the body, Microwave Radiation is absorbed near the skin. At high enough intensities both will damage tissue through heating. Radio emitters and cell phones are sources of microwave radiation and radiofrequency radiation.

• Infrared radiation: also called Thermal Radiation. The skin and eyes absorb infrared radiation (IR) as heat. Sources of IR radiation include furnaces, heat lamps, and IR lasers.
• Visible Light Radiation: the different visible frequencies...
