Meaning
Background radiation is the natural 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 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 average level of background radiation because at high altitude people are exposed to more cosmic rays.
- Miners are exposed to a higher than average level of background radiation because many rocks are sources of ionising radiation.
- Hospital workers are exposed to a higher than average level of background radiation because sources of ionising radiation are used in medical imaging.
