Where does background radiation originate?
Background radiation can come from all sorts of sources, some natural, some man-made.Examples include...cosmic rays from spaceradon gas emitted from the earth's crustelectromagnetic radiation from a number of possible sourcesatomic radiation from nuclear substances.For much more information see Related links below this box.
How does the presence of CMBR support the big bang theory?
Basically, in that it closely agrees to what is expected from the Big Bang - this includes the existence of the background radiation, its approximate temperature, and its anisotropies. For more details, I suggest you read some more about the cosmic microwave background radiation - for example, you might start with the corresponding Wikipedia article.
What is the source of radiation for both the earth's atmosphere and the greenhouse effect?
The Sun is the primary source of radiation for both the Earth's atmosphere and the greenhouse effect. Solar radiation enters the atmosphere, warms the Earth's surface, and is re-radiated as infrared radiation. Greenhouse gases in the atmosphere trap some of this infrared radiation, leading to the greenhouse effect.
If you could block all radiation from sources outside your body explain why you would still be exposed to some radiation?
Some of the elements in your body are naturally radioactive. e.g. potassium, some carbon, etc. You get a larger exposure to radiation from the decay of potassium in your body, than you will from a smoke detector based upon radioactive americium.
What is the source of radiation for both the earth's atmosphere and greenhouse?
The primary source of radiation for both the Earth's atmosphere and greenhouse effect is the Sun. Solar radiation enters the Earth's atmosphere, warming the surface. Greenhouse gases in the atmosphere trap some of this heat, preventing it from escaping back into space.
What is background radiation List some of its sources?
Background radiation is the nuclear radiation that arises naturally from cosmic rays and form radioactive isotopes in the soil and air. Some of its sources are : the sun, heat, soil, rocks, and plants.
What is the concept of radioactivity that's always there?
This is probably a reference to what is called background radiation. Background radiation has a number of contibuting factors, but it is "always there" in some form or another owing to radioactive decay of radioisotopes and to cosmic radiation and its effects.
Where is background radiation highest in the UK?
Background radiation levels in the UK can vary, but typically, it is higher in areas with higher concentrations of certain elements like uranium and radon. Some areas in the southwest of England, such as Cornwall and Devon, have higher levels of background radiation due to the presence of granite rock which contains higher levels of radioactive elements.
What is the difference between cosmic background radiation and red shift?
Cosmic microwave background radiation is a specific radiation. Red shift is a change in frequency due to the fact that an object moves away from us (or for some other reason, such as a gravitational well); and that affects ALL types of radiations.
One of the observable remnants of the Big Bang is?
cosmic background radiation :) This phenomenon can be picked up by an ordinary radio or tv. If your radio is not tuned into a station, then some of the the noise (interference) you hear is the cosmic background radiation caused by the Big Bang.
Why does a Geiger counter occasionally click even if no artificial radioisotopes are nearby?
A Geiger counter can sometimes click due to natural background radiation from sources such as cosmic rays, radon gas, and radioactive isotopes in the earth. These sources can produce random bursts of radiation that the Geiger counter detects as clicks.

What will be tempereture in interstellar space?
It varies quite a bit, between about 3 kelvin (the temperature of the background radiation), to several million kelvin in some areas.
Is there some background radiation from the big bang observed if yes then who observed it?
yes, Arno Penziaz and Robert Wilson picked up the first signals
How was Cosmic Microwave background radiation first discovered?
It as predicted from theory and discovered by accident by two telephone engineers that, when they saw it, thought it was some sort of interference noise in their instrument, (possibly caused by pigeons). When they were unable to eliminate the noise, they spoke about it to an academic friend who realised that what they were detecting may be the predicted microwave background radiation.
What is the source of radiation for both the Earth's atmosphere and the greenhouse?
The primary source of radiation for both Earth's atmosphere and the greenhouse effect is the sun. Solar radiation warms the Earth's surface, which then emits infrared radiation. Some of this infrared radiation is absorbed by greenhouse gases in the atmosphere, trapping heat and warming the planet.
