WebNatural background radiation comes from five primary sources: cosmic radiation, solar radiation, external terrestrial sources, radiation in the human body, and radon. The background rate for natural radiation varies considerably with location, being as low as 1.5 mSv/a (1.5 mSv per year) in some areas and over 100 mSv/a in others. WebTerrestrial radiation is produced by the Earth itself. Natural radioactive materials can be found in soil and rock. Natural reserves of uranium, potassium, and thorium, which produce modest amounts of ionizing radiation during natural decay, are the principal sources.
Web3 May 2024 · The term terrestrial radiation refers to sources of radiation that are in the soil, water, and vegetation. Usually, this term is defined as the sources that remain external to the body that can emit radiation. For example, the most common radionuclides we can observe as terrestrial sources of radiation include potassium, uranium, and thorium ...
