Abstract
Experimental data on the EAS muon number fluctuations obtained with th e Moscow State University EAS array are analysed to derive the primary mass composition at energies before and after the knee. The mass comp osition before the knee (E similar or equal to 10(15) eV) corresponds to that measured by direct methods, while the mass composition after t he knee (E similar or equal to 10(17) eV) is enriched by heavy nuclei.
