The attenuation length of proton primaries and the proton-air inelastic cross section are studied at energies E-0 approximate to 10(15) eV by using the EAS-TOP array data. Proton initiated Extensive Air Showers, in the energy range (2 divided by 4) 10(15) eV and near maximum development, are selected from their N-mu(E-mu > 1 GeV) and N-e sizes. The experimental attenuation length Lambda(obs) is compared with those obtained from simulations, including the full detector response, based on different interaction models (HDPM, VENUS, DPMJET, QGSJET and SIBYLL) in the frame of CORSIKA code. The proton-air inelastic cross section is also inferred by using the factor k = Lambda(obs)(sim)/lambda(p-air)(sim) obtained from each interaction model.
