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.

Is there a difference between background radiation and background count rate?
There is a subtle difference. Background count rate is the measure of how strong the background radiation is.

How ia cosmic background radiation related to the big bang theory?
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.
What are the weaknesses of cosmic background radiation?
the weakness of cosmic back ground radiation as those radiation are left over of big bangs
What is the act of studying the stars?
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).
Is there a difference between background radiation and background count rate?
There is a subtle difference. Background count rate is the measure of how strong the background radiation is.
What can one do to protect oneself from background radiation?
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.

Penzias and Wilson discovered background radiation on October 7,1965.
What is the background radiation?
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.
