Theoretical and experimental problems related to deep underwater muon and neutrino detection by Cherenkov optical radiation from muons and cascades from muons and neutrinos in >~ 107 m3 setups (DUMAND project) are considered. The possibilities for searching for high-energy neutrinos, magnetic monopoles and supersymmetric particles in underwater experiments are pointed out.
The prospects for creating radio muon and neutrino detector ``hearing through'' a volume of 109-1011 m3 in ice massifs with a small decimetric radiowave attenuation are discussed. Ground-base detection of Cherenkov radioemission by extensive air shower (EAS) in the energy range >~ 1019-1020 eV and detection of cascades produced by neutrinos (muons) underground near the Earth's surface by radio-emission entering the atmosphere are considered. For underwater registration of transition (Cherenkov) radioemission of electron-photon or hadron cascades from muons and neutrinos, a system of thin dielectric waveguides can be used.
Estimations show that Cherenkov radio detectors in ice can register fluxes of cosmic electron antineutrinos with energies close to the resonance energy Eres ~ 6 × 1015 eV (reaction νe + e- --> W- --> hadrons), while radio detectors in ice and atmosphere can register fluxes of neutrinos with Eν ~ 1018-1019 eV.
