Answer:
Explanation:
Background Radiation
Background radiation refers to the natural radiation that is always present in the environment. It includes various types of radiation, such as cosmic radiation from the sun and stars, terrestrial radiation from the Earth, and internal radiation that exists in all living things .
Natural Sources of Background Radiation:
Cosmic Rays: These are radiations that reach us from outer space .
Animals: All animals emit a natural level of radiation .
Rocks: Some rocks give off radioactive radon gas.
Soil and Plants: Radioactive material from rocks is absorbed by the soil and passed on to plants .
Artificial Sources of Background Radiation:
X-Rays: When going through security or having an X-ray in the hospital, we are exposed to this type of radiation .
Background radiation is present everywhere and is a result of natural processes. It is important to note that the levels of background radiation can vary worldwide, but we have always been and will always be exposed to it from natural sources .
It is worth mentioning that background radiation is generally low-level radiation and is considered ubiquitous in our environment. It comes from cosmic rays and naturally occurring radioactive materials found in the Earth and living things .
In terms of radiation protection, the goal is to keep long-term environmental exposure, above normal background radiation, to a minimum .
