" Because the ray tracing
routines cannot track across the outermost boundary, all of the regions
must be contained within a surrounding "blackhole" (an infinitely
absorbing
material, in MORSE jargon "external void", designated by the FLUKA
material number 1), so that all escaping particles are absorbed. It is
suggested to
make the external blackhole region VERY big, especially when magnetic
fields are present which could give rise to curved trajectories. The
external
blackhole must be completely surrounded by the boundary of a closed
body, and therefore cannot be defined by means of half-spaces or
infinite
cylinders only. Inside such outermost boundary, each point of space must
belong to one and only one region. "

As for region volumes : I suppose you refer to the scored values at the
end of the output:

from the same manual section:
"Geometry Title card

Three variables are input in the CG Title card: IVOPT, IDBG, TITLE. The
format is (2I5,10X,A60). The first integer value (IVOPT = Input Volume
OPTion)
is a flag to indicate how to normalize the quantities scored in regions
by the FLUKA option SCORE.

    IVOPT = 0 means that no normalization is to be performed (output
              values are total stars or total energy deposited in each
              region).

    IVOPT = 1 and IVOPT = 2 have no meaning in FLUKA and are not
              allowed.

    IVOPT = 3 means that the scores must be normalized dividing by
region
              volumes input by the user just before the GEOEND card.
