X-radiation (which is composed of X-rays‚ hence the name) falls under electromagnetic radiation. X-rays and gamma rays are sometimes confused‚ but they are different‚ as X-rays are emitted by electrons outside the nucleus whilst gamma rays are produced inside the nucleus. X-rays have extremely small

millions of metric tons of coal in a year and polluting the air with harmful carbons‚ nuclear plants use fuel rods as their energy. These rods heat water‚ create steam‚ and generate electricity‚ while not giving off any harmful gases. Atoms and radiation have many applications in agriculture‚ medicine‚ industry and research. They greatly improve the day to day quality of our lives. One interesting use of a radio-active isotope is in reducing insect population. The Sterile Insect Technique (SIT) consists

the hospitals waiting for a doctor to see them and others were dying in the streets by the cause of them being burnt from the fires or from falling debris. The people that received the least visible damage were the people that received radiation sickness. Radiation sickness causes nausea and vomiting‚ hair loss‚ and severe fatigue‚ which is why the six people that Hersey interviewed saw or personally experienced vomiting in Ason Park and little to low levels of energy by the cause of the fatigue‚

Radio waves and Microwaves Radio communications Radio waves are used to broadcast radio or television signals from transmitters‚ which are then converted into electrical signals with an aerial (which is made out of metal to absorb the radio waves) so you can hear and see them. When done so the aerial converts this wave into an electrical signal (because of the electromagnetic waves energy exciting particles in the aerial and causing them to oscillate/vibrate and thus create an electrical current)

Food irradiation: A food safety technology designed to eliminate disease-causing germs from foods. Treating food with ionizing radiation can kill bacteria and parasites that would otherwise cause foodborne disease. Similar technology is used to sterilize medical devices so they can be used in surgery or implanted without risk of infection. The effects of irradiation on the food and on animals and people eating irradiated food have been studied extensively. These studies show clearly that when irradiation
