    "abstract": "From the point of view of radiation safety, interstellar space is not an\nempty void. Interstellar gas and cosmic rays, which consist of hydrogen and\nhelium nucleons, present a severe radiation hazard to crew and electronics\naboard a relativistic interstellar ship. Of the two, the oncoming relativistic\nflow of interstellar gas produces the most intence radiation. A protection\nshield will be needed to block relativistic interstellar gas that can also\nabsorb most of the cosmic rays which, as a result of relativistic aberration,\nform into a beamed flow propagating toward the front of the ship.",
