Open in App
Solution
The correct option is A Cosmic rays
The natural sources of radiation are those which are present in the Nature and emit radiation like α, β, and γ. Hence, these sources are not man-made and do not emit radiation due to man-made causes. Such sources include the cosmic rays from the Sun and other stars, the ores of radioactive elements present in and around the Earth's crust like thorium, uranium, and polonium, etc. However, acid rain is a man-made phenomenon and does not contain any radioactive elements to emit radiation. Nuclear power plants and nuclear explosives are also man-made sources of radiation.
