[en] A study has been made of fluctuations in the muon densities and muon /electron ratios measured in EAS recorded at Haverah Park. The muon densities (R > 50m) are found to be insensitive to variations in the longitudinal development of EAS. The muon/electron ratio is found to be sensitive to shower development for core distances less than 300m
