==Key Stage 4==
===Meaning===
'''Background radiation''' is the natural [[Ionising Radiation|ionising radiation]] all around from different sources in the [[environment]].
===About Background Radiation===
: There are several sources of '''background radiation''' including food, rocks in the ground, [[Radon]] [[gas]] and [[Cosmic Ray|cosmic rays]].
: The level of '''background radiation''' a person is exposed to depends on their diet, job and where they spend their time.
: Pilots are exposed to a higher than [[Mean Average|average]] level of '''background radiation''' because at high altitude people are exposed to more [[Cosmic Ray|cosmic rays]].
: Miners are exposed to a higher than [[Mean Average|average]] level of '''background radiation''' because many rocks are sources of [[Ionising Radiation|ionising radiation]].
: Hospital workers are exposed to a higher than [[Mean Average|average]] level of '''background radiation''' because sources of [[Ionising Radiation|ionising radiation]] are used in medical imaging.
