We have developed and demonstrated the effectiveness of a spectral determination method (SDM) based on the first principle that a radiation measurement spectrum can be expressed as a linear superposition of individual spectra of the radioactive nuclides. In this presentation, we report the development of a method to create LSC standard spectra for SDM using Geant4 simulation data and the convolution method.
