Taustaradiaation

Taustaradiaation, also known as background radiation, refers to the low level of ionizing radiation that is present throughout the environment. This radiation is a natural and persistent feature of the Earth's environment, originating from both natural and artificial sources. Natural sources include cosmic rays from space, radioactive elements in the Earth's crust, and radon gas from the decay of uranium and thorium. Artificial sources include medical and industrial applications of radiation, as well as fallout from nuclear weapons testing and accidents.

Background radiation levels vary depending on geographic location and local conditions. For example, areas with higher concentrations of radioactive minerals or proximity to nuclear facilities may have elevated levels of background radiation. The average global background radiation dose is approximately 2.4 millisieverts per year, with variations ranging from less than 1 millisievert in some locations to over 10 millisieverts in others.

Exposure to background radiation is a normal part of life and contributes to the average annual radiation dose received by humans. While low levels of radiation are generally considered safe, high levels of exposure can pose health risks, including an increased risk of cancer. Therefore, it is important to monitor and manage background radiation levels to ensure public safety and environmental health.
