Abstract :
The Adult Male® and Adult Female®
phantoms of ORNL were modified with Ir-192 source
and additional tally cards from the MCNP® data
library. The lung and eleven soft tissues were used for
the study. The soft tissues include Liver, Stomach,
Ovaries, Testes, Brain, Thyroid, Kidney, Pancreas, Gall
Bladder, Heart, and the Small Intestine. The
computational simulation was achieved using MCNPX
with nps of 107
, and the data set of the lung and soft
tissues derived for Malaysian population [14]. The
relative error, R was <0.05 for F4 and the F6 tallies
across the energy range studied. The results obtained
for 0.1-10.0 MeV energies for the F4 and F6 tallies were
used to estimate the mass stopping power, S/ρ (MeVg1
cm2
) and the linear stopping power, S (MeV/cm). The
result compares favorably among the tissues. This result
is very relevant and useful in validating an on-going
lung and soft tissue model construction
