Abstract. In this paper, we present a Mont Carlo simulation by using the inhomogeneous diusion
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 conrmation of a supernova being of cosmic ray origin.
