Muon particles are produced by the interaction of cosmic rays with molecules in the atmosphere and are decayed to an electron and two neutrinos with a lifetime of 2.2 µs. These electrons move in the water environment faster than the speed of light in the same environment. Therefore, the electrons emit radiation in the blue and violet light range which is known as Cherenkov radiation. In this research, using the Geant4 simulation code, a simple water Cherenkov detector was simulated to study the Cherenkov radiation of electrons caused by muon decay. Using the energy spectrum of optical photons, the detection efficiency of the water Cherenkov detector was calculated 0.067. Also, the mean lifetime and maximum energy of the electrons produced by the muon decay were measured 2.197±0.014 µs and Emax=52.6 MeV, respectively.
