cosmic radiation

[kos′mik]
high-energy particles with great penetrating power that originate in outer space and reach the earth as normal background radiation. The particles include high-energy atomic nuclei.

cosmic radiation

Ionizing radiation from the sun and other extraterrestrial sources. It has a short wavelength, high velocity, and an exceptional ability to penetrate tissue. It accounts for about one tenth of the yearly total of ionizing radiation exposure for each person. Colloquially, it is known as “cosmic rays.”
