Biological effects due to single accelerated heavy particles and the problems of nervous system exposure in space.
The use of accelerated nitrogen and oxygen nuclei with 270 MeV nucleon-1 at the Berkeley Bevatron allowed a beginning to be made of systematic studies of the effects of heavy particles in multicellular organisms. Initial studies will be briefly reviewed. Individual nitrogen particles produced definite light flashes, streaks and interrupted streaks when they crossed light-sensitive parts of the human retina. The possible hazard from primary heavy galactic cosmic ray particles on long-term space flights are discussed, with special attention to the nervous system.

Radiological physics characteristics of the extracted heavy ion beams of the bevatron.
Studies of the depth-ionization properties and the biological effects of heavy ion beams produced at the bevatron have extended work previously done with less energetic beams from other sources. Results indicate that heavy ion beams are suitable for tumor therapy, studies relating to space biology, and fundamental radiobiology.
