It is implied in these two questions that when astronauts reach Mars orbit, they are exposed to MORE cosmic ray intensity than on the earth's orbit. Therefore, a source of cosmic rays must stand beyond Mars, but not so far beyond, because its influence seems affected already by the distance from the earth to Mars (not the moon).
My conclusion from there is: bodies in the solar system, other than the Sun, must emit cosmic rays. Do you agree?

As the name implies, cosmic rays are cosmic in origin. They are high intensity particles which probably originate from very massive objects far outside our solar system: super novae, neutron stars, black holes and the like. Our Sun also emits the occasional cosmic ray, but not with the nearly the same strength as those coming from outside.
Our Earth has a fairly strong magnetic field which deflects most of these particles away from the surface. (Yep, turns out the Earth is a pretty good place to live.) An astronaut traveling to Mars, or anywhere else outside the orbit of Earth, would be susceptible to cosmic rays since he or she would be outside the protection of the the magnetic field.
I assume the astronauts from the Apollo missions were also exposed to cosmic rays, but the length of their missions (less than a week) made the risk acceptable. A trip to Mars and back would take at least two and a half years so the danger would be considerably higher.

The answer is simple. Cosmic rays are only emitted by the sun not from planets.

hi the sunshine from planets is a mirrored image of sunlight changed by means of the exterior or environment reflecting it. Mars is actual a rust ball, for this reason the reddish shade. Jupiter and Saturn the two have gaseous atmospheres that mirror frequently yellows and oranges nevertheless Saturns rings do exchange its shade. Venus is white because of the fact of cloud conceal. Our eyes respond in a non linear trend at low easy stages which extra complicates issues.

As the above answer stated, it is because of the absence of a protective magnetic field around Mars.

Cosmic rays are high energy particles. If a body has sufficient energy, it can emit them.
