Background radiation refers to the low levels of ionizing radiation that are constantly present in the environment. This radiation comes from a variety of natural and man-made sources and is typically harmless in small doses.
Common sources of background radiation include:
1. Cosmic radiation: Radiation from outer space, primarily from the sun and other stars, that reaches the Earth's surface.
2. Terrestrial radiation: Radiation from naturally occurring radioactive elements in the Earth's crust, such as uranium and thorium.
3. Radon gas: A radioactive gas that is produced by the decay of uranium in soil, rocks, and water.
4. Medical procedures: Diagnostic procedures such as X-rays and CT scans can expose individuals to small amounts of radiation.
5. Consumer products: Some consumer products, such as smoke detectors and certain building materials, contain radioactive materials that can contribute to background radiation.
Overall, background radiation is a natural part of our environment and is generally not a cause for concern. However, exposure to high levels of radiation can increase the risk of health problems, so it is important to monitor and limit exposure when possible.

Background Radiation
Background radiation refers to the constant and unavoidable exposure to ionizing radiation that occurs naturally in the environment from various sources. It is distinct from radiation exposure from artificial sources (e.g., medical X-rays or nuclear power plants).
Common Sources of Background Radiation
There are three main sources of background radiation:
- Cosmic Rays: These are high-energy particles from space that constantly bombard the Earth's atmosphere. When these particles interact with atoms in the atmosphere, they produce secondary radiation that reaches ground level.
- Terrestrial Radiation: This comes from naturally occurring radioactive elements present in the Earth's crust and soil. The most common sources are uranium, thorium, and potassium-40.
- Radon Gas: This is a radioactive gas that is present in soil and groundwater. It seeps into buildings and homes through cracks and openings, contributing to indoor radiation exposure.
Levels of Background Radiation
The average global level of background radiation is approximately 2.4 millisieverts (mSv) per year. However, levels can vary significantly depending on location, altitude, and building materials used.
- Location: Areas with higher concentrations of radioactive elements in the soil or nearby uranium mines will have higher background radiation levels.
- Altitude: Radiation levels increase with altitude because of reduced shielding from cosmic rays in the atmosphere.
- Building Materials: Buildings constructed using materials containing radioactive elements (e.g., granite or certain types of concrete) can elevate indoor radiation levels.
Health Effects
Background radiation is a contributing factor to human radiation exposure, but its effects on health are typically small at natural levels. However, exposure to high levels of background radiation can increase the risk of developing certain types of cancer.
