Galactic Cosmic Rays Now Available for Study on Earth, Thanks to NASA (IMAGE)
Caption
In space, astronauts are constantly bombarded by galactic cosmic radiation, comprised of a mixture of highly energetic ions, putting them at increased risk of radiogenic cancers, cardiovascular disease, and potential central nervous system decrements. Proportionally, the numerous white and blue tracks are representative of proton and helium ion strikes while the thicker colored tracks are representative of heavier ions such as oxygen, carbon, and iron nuclei which impart greater damage to cells, tissues, and organs per track.
