Hello Francesco,

My confusion is with the use of terms "analogue" and "analytic". Reading Note 1, I see 'In the "activation study
   mode, the time evolution is calculated analytically'. I took this to mean direct calculation using Bateman equations.

The manual should be corrected to say:
    WHAT(3) : number of \replicas" of the decay of each individual residual
= 0.0: ignored
< 0.0: reset to default
Default = 1.0 for semi-analogue mode, 3.0 otherwise

Sorry, by neutrons, I meant neutrons in the prompt radiation, so that is a different story.

I understand your description on how DOSE-Eq is calculated. I recently did a study trying to understand the effect of
the # of primaries/run and # of runs and/or cycles (batches) on the errors in the time evolution of the dose rates. The
results did not make sense to me. I will post this in another thread. Maybe someone can shed some light.
