Health Threat from Cosmic Rays

The medical threat from cosmic rays is the danger posed by galactic cosmic sun light and solar lively particles to astronauts upon interplanetary missions. Galactic cosmic rays (GCRs) include high energy protons (85%), helium (14%) along with other high energy nuclei (HZE ions). Solar energetic allergens consist primarily connected with protons accelerated from the Sun to substantial energies via closeness to solar flares in addition to coronal mass ejections.
