Popis: Characteristics of γ-ray families with halos (XREC, Pamir) and data of experiments with EAS are analyzed to estimate the proton and helium (p+He) fractions in the primary cosmic radiation at E0 = 1–100 PeV. It is shown that at energies E0 ∼ 1–100 PeV the fraction of p+He remains significant, namely, the fraction of p+He is near 40% at E0 = 10 PeV.
