What is a simple definition of radiation?
What is a simple definition of radiation?
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 a good definition of radiation?
The emission and propagation of energy in the form of rays or waves. The energy radiated or transmitted in the form of rays, waves, or particles. A stream of particles or electromagnetic waves that is emitted by the atoms and molecules of a radioactive substance as a result of nuclear decay.
What is radiation in science simple words?
Radiation is energy that comes from a source and travels through space and may be able to penetrate various materials. The kinds of radiation are electromagnetic (like light) and particulate (i.e., mass given off with the energy of motion). Gamma radiation and x rays are examples of electromagnetic radiation.
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 radioactive means?
As its name implies, radioactivity is the act of emitting radiation spontaneously. This is done by an atomic nucleus that, for some reason, is unstable; it “wants” to give up some energy in order to shift to a more stable configuration.
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 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 explain for kids?
What is radioactivity short answer?
Radioactivity is the process where an atom loses subatomic particles that can emit large amounts of energy. The largest particles produced by radioactivity are called alpha particles, which can be used in smoke detectors. Gamma rays don’t emit particles, but rather immense amounts of energy.
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 are three examples of radiation?
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 and different kinds?
The radiation one typically encounters is one of four types: alpha radiation, beta radiation, gamma radiation, and x radiation. Neutron radiation is also encountered in nuclear power plants and high-altitude flight and emitted from some industrial radioactive sources.
What’s the meaning of radiation?
Medical Definition of radiation. 1 : energy radiated in the form of waves or particles. 2a : the action or process of radiating with radiation of the pain there may be tenderness over the sciatic nerve— J. A. Key. b(1) : the process of emitting radiant energy in the form of waves or particles.
What is a radiation are called?
Light, radio, and microwaves are types of radiation that are called nonionizing. The kind of radiation discussed in this document is called ionizing radiation because it can produce charged particles (ions) in matter. Ionizing radiation is produced by unstable atoms.
