Background radiation can come from all sorts of sources, some natural, some man-made.
Examples include...

There is a subtle difference. Background count rate is the measure of how strong the background radiation is.
Primordial background radiation is in actuality Cosmic Microwave Background. To discover just what Cosmic Microwave Background theories are, visit the URL posted below:http://www.astro.ucla.edu/~wright/CMB.html
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.
Astronomy Astronomy is a natural science that deals with the study of celestial objects (such as stars, planets, comets, nebulae, star clusters and galaxies) and phenomena that originate outside the atmosphere of Earth (such as the cosmic background radiation).
the weakness of cosmic back ground radiation as those radiation are left over of big bangs
There is a subtle difference. Background count rate is the measure of how strong the background radiation is.
Background radiation come from black body radiation which is mostly infrared and microwave. Background radiation is not harmful at all. Fear from background radiation come from confusion of the word radiation where we mostly concern nuclear radiation, but light is also a form of radiation and we live within the bright day light on a normal basis.
If you are referring to 3k background radiation, the Big Bang.
The big bang caused the background radiation.
UV originate from sun. these are high frequency rays.
Background radiation.
cosmic microwave background radiation.
To correct for background radiation, one can use shielding materials such as lead or concrete to reduce exposure. Additionally, using background subtraction techniques during data analysis can help to eliminate the effects of background radiation. Calibration with known standards can also help in quantifying and correcting for background radiation.
Natural background radiation
None, background radiation is the natural radiation present all around us and has been for thousands of years.
Penzias and Wilson discovered background radiation on October 7,1965.
Background radiation - is the 'natural' radiation of the Earth. There are radioactive ores naturally present in the ground that give off small amounts of radiation. This is detectable by instruments, but is of no consequence to humans or animals.
