Radiation is a natural part of the universe. It comes from cosmic rays, the big bang, stars, rocks, soil, and gasses. Even BANANAS are radioactive. Google "radioactive bananas" for a real treat!

Have just finished doing this as part of my GCSE Cheimstry course. 88% of Background radiation comes from natural sources i.e. food, water, space (via cosmic rays) etc.

Also my teacher said Rocks, soil, bricks, wood, stones, and air, are all radioactive materials. :)

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

Radiation we receive is 50% from Radon gas. Surprisingly, Nuclear power plants and reactors emit the least- less than we receive from food or buildings.

A common source of background radiation is radon. It is a naturally occurring substance found in the soil as well as the air in gas form.

That depends on your geophysical location.

Here on Sweden's west coast the granite bedrock provides a large radiation background. Uranium decay and Radon are the largest there.

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.


Why does a Geiger counter occasionally click even if no artificial radioisotopes are nearby?

There's always some background radiation. There's ionizing radiation around -- trace amounts of radioactive substances decaying, cosmic rays penetrating the atmosphere, etc.


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.


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.


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.


Which country has high radiation?

There are several places on the globe that are high in background radiation. Usually they are low lying, river deltas. Bangladesh, and some parts of Africa are especially "hot".


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 causes fluorescence?

Fluorescence is glowing, or giving off light.


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


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.


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.
