Primordial background radiation is in actuality Cosmic Microwave Background. To discover just what Cosmic Microwave Background theories are, visit the URL posted below:

There is a subtle difference. Background count rate is the measure of how strong the background radiation is.
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 weakness of cosmic back ground radiation as those radiation are left over of big bangs

The source of cosmic background radiation filled the entire universe.
The 'big bang' theory.
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.
Backround radiation is an explosion which occured in space, which consists of radiation comming from all directions in space.
cosmic microwave 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.
The radiation left over from the big bang is found in the microwave region of the electromagnetic spectrum. As the universe expanded and cooled, the intense hard gamma radiation that existed became radio waves in the low gigahertz region, characteristic of a temperature around 30 Kelvin.
