The primary cause of much of the cancer in the U.S. is due to radiation, specifically nuclear radiation. A secondary cancer cause is damage to the body's immune systems. Not all types of radiation are the same. Some forms of radiation are softer and weaker such as electromagnetic radiation, which exists in the form of radio waves, infrared, visible light, ultraviolet, x-ray, gamma rays. These soft forms are photons [light waves]. Another type of radiation is harder because it has mass. Nuclear radiation is so named because it is composed of the particles (protons, neutrons) that make up the nucleus of the atom.
So where does this nuclear radiation come from? Most of this exposure is from Galactic Cosmic Rays (GCRs). GCRs are high-energy charged particles that originate outside our solar system. Cosmic rays are produced when a star exhausts its nuclear fuel and explodes into a brilliant supernova. These stars are generally new short-lived massive blue stars of the spectral type O (20-100 solar masses) or blue-white stars of spectral type B (3-20 solar masses). About 85 percent of GCRs are protons (nuclei of hydrogen atoms), 12 percent alpha particles (helium nuclei) and the remainder are electrons and the nuclei of heavier atoms.
The energy levels of GCRs observed in deep space generally lie in the 100 MeV (million electron volts) to 10 GeV (billion electron volts) range. The higher the energy level of these particles; the greater the speed and thus the ability of the particle to drill down through our atmosphere to the planet's surface. Because most cosmic-ray primaries are strongly influenced by the Earth's magnetic field and the interplanetary magnetic field, most of those detected near the Earth originally had kinetic energies in excess of about 1 GeV (about 87 percent the speed of light)...........
