Good afternoon Experts,
I have a basic question on how does the calculation work for a volumetric source.
If I have a RCC source of 1.4 cm radius and 15 cm L and I give no. of primaries as 1.0E07. Then from where the photons would originate ? As in the case of a point source, the primaries seem to originate from the point itself… how would the photons be travelling from a volume source ? Would it be 1.0E07 from the full volume or no. of photons per unit volume will originate from a unit specific volume?
Another way to ask, if I choose to use a volumetric source in a shielding problem, should I use more no. of primaries to get a good statistics, in comparison to a point source with smaller no. of primaries ?
( thought is: photons concentrated at a point Vs. photons over a defined volume - how it works ?).
Thanks and regards,
