Abstract. In this paper, we present a Mont Carlo simulation by using the inhomogeneous di usion equation suggested by Lagutin et al. in a fractal interstellar medium for a supernova, as being the main source of Galactic cosmic rays in an energy range up to 1016ev. When the numerical results of this simulation are compared with the predicted energy density of cosmic rays from the supernova model of Erlikyn and Wolfendale (EW), they show a strong consistency with the observed experimental parameters of cosmic rays, i.e. Galactic radial gradient, percentage of total supernova energy transfer to cosmic particles etc., which is also con rmation of a supernova being of cosmic ray origin.
