Abstract: A simulation method of nuclear pulse signal based on Monte Carlo method was presented in this paper. And the important technical points of direct sampling and replacement sampling in Monte Carlo were introduced. Software simulation of the negative exponential signal， the sinusoidal signal and nuclear pulse signal containing noise was achieved in VC++ integrated development environment. Simulation results show that the nuclear pulse signal simulated with Monte Carlo method can describe a real situation of radiation-site and will meet the requirements of the simulation of random nuclear pulse signal.
