We present here calculations of radio emission from neutrino induced showers in the context of detection of high energy particles in large volumes employing the radio waves that the shower generates. The medium chosen is salt, one of the media proposed by Askaryan, which can be found in large volumes throughout the world, including in Romania. We have performed simulations of neutrino-nucleon charged-current and neutral-current interactions in the HERWIG code, in the 10(12) - 10(17) eV energy range and then injected all of the resulting particles in GEANT4 code, for the low energy primaries, and in AIRES code, for the higher energies. The calculation of the radio signal was performed considering the entire shower evolution, by taking into account in the equations the longitudinal profile. The aim of this study is to investigate whether different interactions can be discriminated in an experiment for detection of high energy particles based on registering the radio emission from the showers they initiate.
