Answer 2

Cosmic rays are high energy rays which are also known as gamma radiations, these gamma radiations originate from decaying surroundings as if in sun's fission processes or stars burning !
Well these gamma rays are very strong and high energy rays due to their high frequency,
Gamma rays can kill living cells on which they're incident.
They can affect the photographic plates.
Gamma rays are very dangerous if exposed for a long time on anything.
They have high penetrating power due to their small Wavelength and thus they are harmful.
