Because of shielding of the atmosphere and Earth's magnetic field, cosmic rays have very little effect upon us, the average person receiving less than half a millisievert, although some sources report up to 2.5 mSv annually. The recommended maximum is about 1000; which is more likely to be encountered only by an astronaut on an extended mission. Negative effects on human tissue include DNA damage, cancer-like effects, or a kind of cataract, brain and neurological effects, and possibly acceleration of Alzheimer's. Some astronauts in the Apollo program reported seeing light flashes, which may have been related to cosmic ray collision with the retina, optic nerve, or visual cortex in the brain, but no permanent damage was expected to result.
Cosmic rays are high-energy particles that can penetrate through the human body, potentially causing damage to cells and DNA. Prolonged exposure to cosmic rays can increase the risk of cancer and other health issues. However, Earth's atmosphere provides some protection against cosmic rays, and the risk for most people on the ground is relatively low.

No, it is not possible to stop cosmic ray showers. They are high-energy particles from outer space that constantly bombard Earth's atmosphere. However, Earth's atmosphere acts as a shield, absorbing and deflecting most of the cosmic rays before they reach the surface.
Not unlike wind, the human eye can't see cosmic rays directly, but their effects can be made quite visible, using various techniques. In cloud or bubble chambers, the cosmic ray collides with sufficient energy to leave a visible trail, albeit somewhat briefly, but the path of the cosmic ray becomes easily apparent. In spark chambers a technique using charged plates can cause sparks to jump between plates when the path of a cosmic ray creates an ionization channel along its path. Other techniques involve materials which will generate light when a cosmic ray strikes its surface, which can trigger electronics to amplify or make audible. The word 'quantum' may be somewhat redundant in this context; remembering that a cosmic ray is actually made of of particles, be they protons or atomic nuclei traveling at high speed - they are really matter and not electromagnetic radiation as the name might suggest. Since matter does exist in discrete physical units or quanta, loosely one might say that all matter is quantized.
The cosmic ray flux is higher at the poles compared to the equator due to the Earth's magnetic field deflecting many cosmic rays away from the equator and towards the poles. At the equator, the magnetic field is more parallel to the cosmic rays, allowing them to penetrate deeper into the atmosphere and be absorbed before reaching the surface.
That is a very good question. Nobody thought on this probably. Cosmic rays are in the form of microwaves. They give heat to you. They are not harmful to you. They heat up the atmosphere to very little degree. As such their usefulness can be questioned. Cosmic rays are great curiosity in astrophysics.

Exposure to beryllium x-ray radiation can have harmful effects on human health, including increasing the risk of developing cancer, damaging cells and tissues, and causing skin burns. It is important to limit exposure to beryllium x-ray radiation to protect overall health.

Cosmic ray: A ray of radiation of extraterrestrial origin, consisting of one or more charged particles such as protons, alpha particles, and larger atomic nuclei. Cosmic rays entering the atmosphere collide with atoms, producing secondary radiation, such as pions, muons, electrons, and gamma rays. Cosmic rays (and secondary radiation) can be easily seen in a cloud chamber.(American Heritage Dictionary, 2005)
