Radiation is energy that comes from a source and travels through space and may be able to penetrate various materials. Light, radio, and microwaves are types of radiation that are called nonionizing. Gamma radiation and x rays are examples of electromagnetic radiation.
What is the best definition of radiation?
Radiation is the emission and propagation of energy in the form of waves, rays or particles. Sources of non-ionizing radiation include light, radio, microwaves, infrared (heat), and ultraviolet light.
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 examples?
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.
What is radiation in a sentence?
Definition of Radiation. energy spread or radiated through waves, particles, or rays. Examples of Radiation in a sentence. 1. Although the explosion was contained inside of the plant, the chemical radiation can still spread within a thirty-mile radius.
What is radiation explain?
Radiation is energy that comes from a source and travels through space at the speed of light. This energy has an electric field and a magnetic field associated with it, and has wave-like properties. You could also call radiation “electromagnetic waves”.
What is meant by radiation 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.
How do you explain radiation to a child?
Radioactivity is simply when very small particles in objects emit energy or smaller particles. The energy that is produced can result in cancer, serious environmental damage, or helpful technologies. There are different degrees of radioactivity, and different exposures increase the harm it can cause.
What is radiation study?
Radiation can be defined as the transition of energy from one body in the form of waves or particles. Radiation can be split into the two main categories of non-ionizing and ionizing radiation. Ionization is the process in which an atom loses or gains an electron to become positively or negatively charged.
What does radiation mean in chemistry?
Radiation is the emission of energy through space in the form of particles and/or waves. Nuclear reactions are very different from chemical reactions. In chemical reactions, atoms become more stable by participating in a transfer of electrons or by sharing electrons with other atoms.
Why is it called radiation?
The word radiation arises from the phenomenon of waves radiating (i.e., traveling outward in all directions) from a source.
What is the process of radiation?
Radiation is the process by which energy is emitted as either particles or waves. Broadly, it can take the form of sound, heat, or light. However, most people generally use it to refer to radiation from electromagnetic waves, ranging from radio waves, though the visible light spectrum, and up through to gamma waves.
What is radiation and its causes?
Radiation is the energy released from atoms as either a wave or a tiny particle of matter. Radiation sickness is caused by exposure to a high dose of radiation, such as a high dose of radiation received during an industrial accident.
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 a radiation picture?
A procedure that uses a computer to create a picture of a tumor to help guide the radiation beam during radiation therapy. The pictures are made using CT, ultrasound, X-ray, or other imaging techniques. Image-guided radiation therapy makes radiation therapy more accurate and causes less damage to healthy tissue.
