Lateral distribution functions of particles in extensive air showers with the energy E0≃1019 eV recorded by ground-based and underground scintillation detectors with a threshold of Eμ≃1.0×secθ GeV at the Yakutsk array during the continuous observations from 1986 to 2016 have been analyzed using events with zenith angles θ≤60∘ functions have been compared to the predictions obtained with the QGSJet01 hadron interaction model by applying the CORSIKA code. The entire dataset indicates that cosmic rays consist predominantly of protons.
