Meaning of "unit primary weight"

Can you tell please what does it mean “unit primary weight” ?

In normal conditions it just means “per primary history”, i.e. per beam particle. This implies that the FLUKA result has eventually to be multiplied by your beam intensity or current.
However, the adopted wording is meant to properly cover also the case where one assigns a different statistical weight to each primary history, by means of the source.f user routine.
