We consider a simulation for radiation diffusion with consideration for geographic data. In our simulation scheme, each particle is simulated as a Markov chain with a transition function which is dependent on some geographic data, and we assume that the each particle moves independently. Then due to the effect of the law of large numbers, the real observed value can be approximated by the expectation of the Markov chain. In this paper, we simulate a large number of the paths of particles to see the influence of geographic data and analyze the structure called “Hot spot”.
