Atmospheric radiation can also be said to be infrared radiation which is released by or also produced by the atmosphere.
2. Research including the detection of microwave thermal radiation and similar weak wide-band signals that resemble noise and are obscured by receiver noise: The primary atmospheric radiation measurement application using an atmospheric radiometer has been on board spacecraft measuring atmospheric and terrestrial radiation, and they are mostly used for meteorological or oceanographic remote-sensing.
Their secondary application is also meteorological, as zenith-pointing surface instruments that view the Earth's atmosphere in a region above the stationary instrument.
By understanding the physical processes associated with energy emission at these wavelengths, scientists can calculate a variety of surface and atmospheric parameters from these measurements, including air temperature, sea surface temperature, salinity, soil moisture, sea ice, precipitation, the total amount of water vapor and the total amount of liquid water in the atmospheric column directly above or below the instrument.
2. Any undesired electromagnetic disturbance.
Types include gamma radiation, X-rays, ultraviolet, visible, and infrared radiation, and radar and radio waves.
2. Radiation that is produced with a combination of magnetic and electric forces.It exists as a continuous spectrum of radiation, from that with the highest energy level and the shortest wavelength (gamma rays) to that with the lowest energy and longest wavelength (long radio waves).
All forms of electromagnetic radiation travel at the speed of light.
Light, radio waves, and X-rays are forms of electromagnetic radiation. Almost all of our knowledge of extraterrestrial objects comes from emitted or reflected electromagnetic radiation (visible light or radio waves).
Gamma emission usually occurs as part of alpha or beta emissions; however, they are less ionizing in their effect than alpha and beta particles, but are dangerous nevertheless because they can penetrate deeply into body tissues; such as, bone marrow.
Controlled application of gamma radiation is important in the diagnosis and treatment of various conditions, including skin cancer and malignancies deep within the body.
Gamma radiation is also used to kill bacteria and other micro-organisms, to sterilize medical devices, and to change the molecular structure of plastics to modify their properties.
The risk of cell death or injury from radiation depends on the type of tissue cells, the stage of cell division at the time of exposure, the intensity and time span of exposure, and the type of radiation administered.
It includes non-particulate radiation; such as. X-rays, and radiation produced by energetic charged particles; such as, alpha and beta rays, and by neutrons, as from a nuclear reaction.
2. Particulate or electromagnetic radiation that produces ionization in a medium through which it passes.3. Any radiation; such as, a stream of alpha particles or x-rays, that produces ionization as it passes through a medium.
4. Particles or photons that have sufficient energy to produce ionization directly in their passage through a substance.
5. Particles that are capable of nuclear interactions in which sufficient energy is released to produce ionization.
6. Photons of high-energy electromagnetic radiation and particle forms of radiation that have sufficient energy to produce ions by removing electrons from atoms or molecules.
2. A medical patient who has been subjected to whole body irradiation to lower immune responses to foreign donor cells and therefore has the immunological characteristics of both host and donor after a bone marrow graft from the antigenically different donor.
Terrestrial radiation is the radiation that is released by naturally occurring radioactive materials in the Earth; such as uranium, thorium, and radon.
2. A process by which energy is emitted by a warm surface.
The energy is electromagnetic radiation and so travels at the speed of light and does not require a medium to carry it.
3. The energy radiated by solids, liquids, and gases as a result of their temperature.Such radiant energy is in the form of electromagnetic waves and covers the entire electromagnetic spectrum, extending from the radio-wave portion of the spectrum through the infrared, visible, ultraviolet, x-ray, and gamma-ray portions.
2. The use of energy waves that diagnose or treat disease.
Measured by a pyrheliometer with a solar aperture of 5.7 degrees to transcribe the solar disc.
Such radiation results commonly from the acceleration of an electric charge, and is propagated in a vacuum at the speed of light.
2. The part of the electromagnetic spectrum that lies between the microwave and visible wavelengths.
People know about the stars because they can be seen and because of this, optical telescopes are the traditional instruments of astronomy; however, it must not be forgotten that light is only one form of electromagnetic radiation, and that it forms only a narrow band in the electromagnetic spectrum.
It is interpreted in the "big bang theory" as the remnant of the initial explosion.
It is characterized by being polarized.
The radiation is an example of line emission.
The atomic particles came from the earth's upper atmosphere and the solar wind, and are trapped by the earth's magnetic field.
The inner belt lies above the equator, and contains protons and electrons from the solar wind.
2. One of two regions, lying at about 1,900 miles, 3,000 kilometers, and 12,500 miles, 20,000 kilometers, above the equator, in which charged particles, trapped in the earth's magnetosphere, oscillate between the magnetic poles.The particles are caught from the solar wind or produced by collisions between air molecules and cosmic rays.
