What is radiation in 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 the meaning of radiation 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. The radiation of heat and light from a fire.
What is radiation called?
Related Pages. 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 are two forms of radiation?
There are two kinds of radiation: non-ionizing radiation and ionizing radiation. Non-ionizing radiation has enough energy to move atoms in a molecule around or cause them to vibrate, but not enough to remove electrons from atoms. Examples of this kind of radiation are radio waves, visible light and microwaves.
What are sources of radiation?
The majority of background radiation occurs naturally from minerals and a small fraction comes from man-made elements. Naturally occurring radioactive minerals in the ground, soil, and water produce background radiation.
What is the biggest source of radiation?
radon
What is the greatest source of radiation?
By far the largest source of natural radiation exposure comes from varying amounts of uranium and thorium in the soil around the world. The radiation exposure due to cosmic rays is very dependent on altitude, and slightly on latitude: people who travel by air, thereby, increase their exposure to radiation.
What are the main sources of ionizing radiation?
Ionizing Radiation from Natural Sources
- Radiation from space (cosmic and solar radiation)
- Radiation from the earth (terrestrial radiation) Radon.
- Radiation from building materials.
What are the sources of non-ionizing radiation?
What is non-ionizing radiation?
- Radiofrequency (RF) radiation used in many broadcast and communications applications.
- Microwaves used in the home kitchen.
- Infrared radiation used in heat lamps.
- Ultraviolet (UV) radiation from the sun and tanning beds.
