The lateral distribution function of high energy muons in EAS around the knee ( 5.9 \leq \lg N _ { e } \leq 7.1 ) has been measured for near vertical showers ( \theta \leq 20 ^ { \circ } , effective muon threshold energy is 230 GeV ) . The measurements have been performed at the Baksan Underground Scintillation Telescope ( BUST ) . The electromagnetic component is measured by the ” Andyrchy ” EAS array , located above the BUST . The knee in EAS size spectrum is found to be at \lg N _ { e } \approx 6.3 . The experimental results are compared with Monte Carlo simulations .
