Cosmic radiation and radiation from terrestrial sources are examples of?
Natural background radiation
Cosmic radiation External terrestrial and internal radiation
Radiation is the process by which energy is emitted from a source and propagated through the surrounding medium, or the energy involved in this process. Radiation consists of a flow of atomic or subatomic particles or of waves. Familiar examples are light (a form of electromagnetic radiation) and sound (a form of acoustic radiation). Both electromagnetic and acoustic radiation can be described as waves with a range of frequencies and intensities. Electromagnetic radiation is also… Read More
The background radiation is due to radiations from the cosmic space or from radioactive isotopes on the earth.
Background radiation can come from all sorts of sources, some natural, some man-made. Examples include... cosmic rays from space radon gas emitted from the earth's crust electromagnetic radiation from a number of possible sources atomic radiation from nuclear substances. For much more information see Related links below this box.
- Radiation of cosmic origin - Radiation from radioactive elements (and decay products) of the Earth - Internal radiation of organisms
Alpha, Beta, Gamma and cosmic are all examples of radiation. Types of radiation could be: Ionizing radiation Electromagnetic radiation Infra red radiation
earths crust, radon gas, cosmic rays, natural sources e.g food, water and rocks.
1.Sources from Earth such as water and food and from humans 2.Sources from outer space such as cosmic rays 3.Sources in the atmosphere such as radon gas released from the earth's crust
Solar radiation comes from "our" star - the Sun. Almost all other radiation which reaches earth comes from other "suns" - the stars, whether great or small. A small amount of radiation is left over from the Big Bang - and is known as "Cosmic microwave background radiation".
the weakness of cosmic back ground radiation as those radiation are left over of big bangs
Alpha, Beta, Gamma, Cosmic Or infra-red, visible, and ultra-violet. Or ultrasonic, audio, and infrasonic.
The source of cosmic background radiation filled the entire universe.
In the 1960s, microwave radiation was detected coming from space and no particular source, and this radiation was dubbed the Cosmic Microwave Background Radiation (CMBR).
Terrestrial raiation are those radiatins which originate from the earth's surface as there are radioactive substances in the earth's crust. Even from your own bones which cntain radium compunds. Extraterrestrial radiatins include those coming from space like cosmic waves, sun's rays, etc.
Earth's atmosphere and magnetic field are the main protection factors from cosmic radiation.
Then it will not emit any more radiation - except that it will eventually re-emit any radiation it receives, especially the cosmic background radiation.

Sources of radiation include Coal fired owed plants Depleted uranium shells from military use Gypsum wall board Granite (counter tops etc) Radon gas from soil Natural Uramium Cosmic rays Sunlight Smoke detectors X-ray machines Industrial nuclear inspection sources
The evidence of cosmic microwave background radiation supports the Big Bang theory.
Gamma rays are typically produced by the decay from high energy states of atomic nuclei, called gamma decay, but they are also created by other processes. For instance, gamma rays are also produced by secondary radiation from atmospheric interactions with cosmic ray particles. Also, rare terrestrial natural sources produce gamma rays that are not of a nuclear origin, like lightning strikes and terrestrial gamma-ray flashes. Plus, they are produced by astronomical processes where very high-energy… Read More
There are two factors which determine the relative level of cosmic radiation at different points on the earth's surface. First, because the earth's magnetic field deflects the charged particles in cosmic radiation toward the magnetic poles, cosmic radiation levels are generally higher the closer you are to a magnetic pole, i.e., the higher your geomagnetic latitude. Second, since the earth's atmosphere provides physical shielding from cosmic radiation, cosmic radiation levels are generally higher at higher… Read More
The cosmic background radiation was discovered in 1964 by American radio astronomers Arno Penzias and Robert Wilson
the big bang caused the cosmic background radiations
The cosmic background radiation is believed to be the remains of the radiation emitted by the Universe when it started to get transparent - when it had cooled down to a temperature of about 3000 kelvin.
the cosmic background radiation are microwaves and not photons but if there are some then they are leftovers of the big bang 13.7 billion years ago
As far as we can tell cosmic radiation has been present since the beginning of time. It comes from the cosmos starting at the big bang.
It is believed that the cosmic background radiation was created at the beginning of the universe, thus they come from the of the universe. We can fell it on Earth, using telescopes.
The cosmic microwave background radiation has a black-body spectrum with a temperature of 2.7 K (2.7 Kelvin, or about -270.5 oC).
The big bang caused the background radiation.
Basically, the background radiation is in agreement with that which is expected from the Big Bang theory. You can find more details in the Wikipedia article "Cosmic background radiation".
The cosmic background radiation is an observation of the effects of the Big bang [See related question] it does not effect the Universe changing in anyway.
Where is the cosmic rays radiation located on the electromagnetic spectrum in relation to other kinds of radiation?
Cosmic rays are not part of the EM spectrum -- they are high energy charged particles.
Mainly that the cosmic microwave background radiation agrees closely with that which is expected, assuming there has been a big bang.
Cosmic microwave background radiation.
Which theory of the universe did the 1964 discovery of cosmic microwave background radiation support?
I didn't check the year... But the cosmic background radiation is said to support the big bang theory, because it agrees with the radiation that is expected from an expanding Universe.
The discovery of cosmic rays, like many discoveries, unfolded over a period of time as understanding increased as to their nature. Some may say that Henri Becquerel discovered them along with other forms of ionizing radiation in 1896. In 1909 a device developed by Theodor Wulf showed that a certain type of radiation was higher with an increase in altitude, which was likely explained by the shielding effect of the atmosphere against cosmic rays. A… Read More
The film badges (radiation dosimeters) indicate if a pilot has been exposed to higher levels of ionizing radiation, as from cosmic rays at high altitudes, or from other sources. Limiting the periodic exposure prevents unsafe effects on the flight personnel. Most US pilots now use a different device, a thermoluminescent detector or TLD. So for short: Because they work at high altitudes, pilots are exposed to high levels of background radiation from cosmic rays. To… Read More
CMB is an acronym for Cosmic Microwave Background. It could also mean Compagnie Maritime Belge, which is a maritime group.
Cosmic ray: A ray of radiation of extraterrestrial origin, consisting of one or more charged particles such as protons, alpha particles, and larger atomic nuclei. Cosmic rays entering the atmosphere collide with atoms, producing secondary radiation, such as pions, muons, electrons, and gamma rays. Cosmic rays (and secondary radiation) can be easily seen in a cloud chamber. (American Heritage Dictionary, 2005)
no they are not. NASA suggests that the spectrum of electromagnetic radiation does not include cosmic rays.
Ozone layer protects from cosmic radiations. These radiations are very harmful.
There are many discoveries in physics that can be used as examples. The best would be the WMAP mission which discovered that the cosmic microwave background radiation fit the theoretical model almost perfectly.
The big bang
About 2.7 Kelvins
The cosmic background radiation helps confirm the Big Bang theory - which predicted that there should be such a background radiation, as a remnant of an early hot Universe. Also, it can - and is - being studied to learn more details about the early Universe.
A Space Orbiter has no special built-in protection against cosmic rays. This is because it is designed for short missions (so the crew are not exposed to cosmic radiation for long) in low Earth orbit under the van Allen Belts (which act as a shields against solar and cosmic radiation).
Cosmic rays are a type of radiation we experience that originates in outer space. The catch is that they really aren't "rays" as we know them, but are actually particulate radiation. They're little bits of matter that have been highly accelerated and come flying at us. Most (about 90%) of the "cosmic rays" are actually high energy protons. They could be thought of as hydrogen nuclei (H+). Another 9% are alpha particles, or helium nuclei… Read More
