MC simulations for single source dosimetry are ALWAYS a set of
2 MC
simulations
one
for the distribution of energy absorbed
at all points of the geometry per starting particle
and
one
for the air kerma of the source per starting particle
In multiple source MC dosimetry (e.g. a clinical case) results from single
source positions can be weighed by t
i
, summed
and multiplied by TRAK (S
K
*t
tot
)
The MC method …
