Answer: Gamma radiations does not reach the surface of the earth.
Explanation: Sun radiates all of these radiations but one of them does not reach the surface of Earth.
Most of the radiations which reaching the Earth's surface are visible and infrared radiations.
Ozone layer which is present in the atmosphere of Earth prevents the UV radiations to reach the Earth's surface but does not completely prevents. Hence, a small amount of ultraviolet radiations reaches the Earth's Surface.
Gamma radiations are produced by the Sun as a result of nuclear fusion reactions but these radiations have a very low wavelength and are unable to reach the Earth's Surface.
Hence, Gamma radiations does not reach the surface of the earth.
