Natural background radiation has how many components?

Natural background radiation consists of three primary components, which is why the answer is three components. These components include cosmic radiation, terrestrial radiation, and internal radiation.

Cosmic radiation originates from outer space, including high-energy particles that interact with the Earth's atmosphere. Terrestrial radiation comes from radioactive materials in the Earth, such as uranium, thorium, and radon, which decay and emit radiation. Internal radiation results from radionuclides present within the human body, primarily from the food and drink we consume, such as potassium-40 and carbon-14.

Understanding these components is crucial for assessing exposure risks and implementing safety measures in environments where radiation is present.
