We have developed a MONTE CARLO code that simulates the effects that the cold
torus gas, has on the intrinsic power-law shaped x-ray spectrum of AGN. The
code aims to simulate absorption due to photo-ionization, Iron fluorescence and
Compton down-scattering. The code focuses mainly on obscured AGN spectra (so
called Compton thick, column density NH>1024cm-2). The code uses random numbers
to simulate the photons’ position following a random walk The main techniques
used to build the code are described in the paper by Pozdnyakov, Sobol and
Sunyaev (1983). An input spectrum following a power – law distribution is
simulated and introduced in an absorbing and scattering medium, the code
follows each photon recording its energy and position until it leaves the
medium thus producing an output spectrum
