  The main interest of the present work is in analyzing the lateral
distribution function (LDF) of Cherenkov radiation from particles that produced
in Extensive Air Showers (EAS). The simulation of Cherenkov radiation LDF is
fulfilled by utilizing the CORSIKA program at 1 PeV of the primary energy
around the knee region for many primaries for vertical showers for Tunka-133
array conditions. Depending on the numerical simulation results of Cherenkov
light LDF, sets of parameterized polynomial functions are resetted for several
particles as a function of primary particle type. The comparison between the
approximated LDF of Cherenkov radiation with the LDF which has been simulated
using CORSIKA program for Tunka-133 array is verified for several primary
particles for vertical EAS cascade.
