What is radiation in Kid definition?
Radiation is energy that moves from one place to another. Light, sound, heat, and X-rays are examples of radiation. The different kinds of radiation fall into a few general categories: electromagnetic radiation, mechanical radiation, nuclear radiation, and cosmic rays.
What is radiation definition and example?
Radiation is the process of sending off energy in the form of light, heat, x-rays or nuclear particles. An example of radiation are the energy waves off of a nuclear bomb. The transfer of energy via radiation (as opposed to convection or conduction).
What is radiation and why is it harmful?
Radiation damages the cells that make up the human body. Low levels of radiation are not dangerous, but medium levels can lead to sickness, headaches, vomiting and a fever. High levels can kill you by causing damage to your internal organs. It’s difficult to treat high radiation exposure.
What is a sentence for radiation?
Examples of radiation in a Sentence She was exposed to high levels of radiation. He goes in for radiation next week.

What is the definition of radiation for Class 7?
Radiation: The process of the transfer of the heat from one place to another place without heating the intervening medium is called radiation. For example, the heat from the sun reaches the earth through radiation mode.
What are the uses of radiation?
Today, to benefit humankind, radiation is used in medicine, academics, and industry, as well as for generating electricity. In addition, radiation has useful applications in such areas as agriculture, archaeology (carbon dating), space exploration, law enforcement, geology (including mining), and many others.
What is a real life example of radiation?
Radiation Examples ultraviolet light from the sun. heat from a stove burner. visible light from a candle. x-rays from an x-ray machine.
What is radiation in 4th grade physics?
4. Radiation is the transfer of energy through waves (electromagnetic radiation) or fast traveling particles (particulate radiation). Radiation can be in the form of heat, sound and light. Radiation can be felt or seen like light or detected through special instruments like X-ray.

What is the meaning of radradiation?
Radiation : Definition 1 Ionizing radiation has sufficient energy to break atoms to create ions. Eg: electric power. 2 Non ionizing radiation causes atoms to move in the molecule only. Eg: microwave heating the food. More
What grade science is convection conduction and radiation?
5TH GRADE SCIENCE – CONVECTION, CONDUCTION, AND RADIATION. Heat travels through liquids and gases by convection. As the molecules get hotter, they begin to move more rapidly. This movement sets up currents in the liquid or gas. The warmer molecules rise and the cooler molecules sink.
