The Beamforming Elevated Array for COsmic Neutrinos (BEACON) detects ultra-high-energy tau neutrinos via radio signals from upward-going extensive air showers (EAS). Scintillators at the BEACON prototype are being used to assist with the initial cosmic ray (CR) search. A calibration of the scintillator array was performed by comparison of measurements and simulations with previous studies of the CR muon flux. Here, we present the results of this calibration and simulations of signals for CR events.
