hello, first thanks for the fast responses.

The steps are:

1║ shot a primary gamma

2║ at its point of emission I want this gamma to interact

3║ I want any valid interaction to randomly occur (ie the gamma interacts, and I don't care about what process makes the interaction)

4║ if the gamma survives to the interaction (say, a compton process occured) I don't want to re-force the interaction

You got that idea perfectly.

I want to repeat the simulation of the following paper:

Generation of photon energy deposition kernels using the EGS Monte Carlo code Phy. Me. Biol., 1988, Vol 33, No 1, 1-20

In this article, on page 2, the authors say:

"An EGS user code called SCASPH (scatter spherical) modelled the passage of photons and charged particles in a homogeneous sphere of water with a radius of 60 g cm-2. Incident photons were forced to interact at centre of the sphere and secondary particles generated..."

Thanks again, JosÚ
