With the aid of using the most recent cosmic ray spectra up to 2x10/sup 20/ eV, production spectra of high-energy neutrinos from cosmic ray interactions with interstellar gas and extragalactic interactions of ultrahigh-energy cosmic rays with 3K universal background photons are presented and discussed. Estimates of the fluxes from cosmic diffuse sources and the nearby quasar 3C273 are made using the generic relationship between secondary neutrinos and gammas and using recent gamma ray satellite data. These gamma ray data provide important upper limits on cosmological neutrinos. Quantitative estimates of the observability of high-energy neutrinos from the inner galaxy and 3C273 above atmospheric background for a DUMAND-type detector are discussed in the context of the Weinberg-Salam model with sin/sup 2/ theta/sub ..omega../ = 0.2 and including the atmospheric background from the decay of charmed mesons. Constraints on cosmological high-energy neutrino production models are also discussed. It appears that important high-energy neutrino astronomy may be possible with DUMAND, but very long observing times are required.
