Cosmic radiation (also known as cosmic rays) is created in deep space by strong electric and magnetic processes, stripping atoms down to the core and accelerating them to high velocities. Those high energetic particles reach the surface of Mars due to the very thin atmosphere. Like all other ionizing radiation it causes damage to material and health.

Point of origin
Cosmic radiation strikes bodies in the solar system from all directions, as they permeate the galaxy. They are made of the same particles in the same proportion as those originating from the sun; and are considered part of space weather.[1].
Note that cosmic rays are blocked by planets, so people on a planet (or in close orbit around one), receive half the cosmic rays that you would in deep space. (The horizon blocks out half the sky, a bit more if you are in a valley.) Cosmic rays will (and their Secondary radiation) will penetrate fairly deep thru earth and rock, so only by being deep underground can they be totally eliminated.
Acute effects on equipment
A single strike by a cosmic ray can cause three types of error in electronic equipment[1]:
