Biological Effects of Stellar Collapse Neutrinos
Massive stars in their final stages of collapse radiate most of their binding
energy in the form of MeV neutrinos. The recoil atoms that they produce in
elastic scattering off nuclei in organic tissue create radiation damage which
is highly effective in the production of irreparable DNA harm, leading to
cellular mutation, neoplasia and oncogenesis. Using a conventional model of the
galaxy and of the collapse mechanism, the periodicity of nearby stellar
collapses and the radiation dose are calculated. The possible contribution of
this process to the paleontological record of mass extinctions is examined.Comment: gzipped PostScript (filename.ps.Z), 12 pages. Final version, Phys.
