Where could I find information about proton radiation in space and information dealing with the penetration of protons in matter with energies typical of those found in space?
Since protons are present in the Van Allen belts, and in solar and galactic cosmic rays, places to search are various National Aeronautics and Space Administration (NASA) and National Oceanographic and Atmospheric Administration (NOAA) Web sites, including the NOAA Space Environment Center in Boulder, NASA Goddard and Marshall Space Flight Centers, the Jet Propulsion Laboratory, NASA Langley and Lewis Research Centers, NASA Johnson Space Center, and the education links on the NASA Headquarters Web site. Another source of information is the Proceedings of the Biennial COSPAR (Committee on Space Research) plenary meeting that are published in Advances in Space Research. Representative URLs include: • The Exploration of the Earth’s Magnetosphere • NASA Human Spaceflight • Science @ NASA • NOAA’s Space Environment Center (Proton spectra and particle data from the GOES satellites can be viewed and downloaded for use.) • Cosmic Rays • Solar-Terrestrial Physics Division of the National Geophy
