7.9 explain the sources of background radiation

There are so many sources of background radiation: different radioactive materials are in the environment.
An example of this is boron in the soil which emits radiation; cosmic rays from space are radioactive too.

50% radon gas from the ground, 12% buildings and the ground, 12% food and drink, 12% cosmic rays, 14% artificial sources - mainly cosmic rays, small amount of nuclear power and weapons test
