In the present work, transmission factor, linear and mass attenuation
coefficients, HVL and TVL values for ordinary, barite, serpentine
and steel–magnetite concretes have been calculated and
simulated using MCNP-4C Code based on the elemental composition
of the concretes, and in order to validation of simulation results,
available experimental results reported in references were
compared with them.
All simulation results formerly validated by experimental data,
demonstrated that steel–magnetite concrete of high density
(5.1 g cm1 density) and with constituents of relatively high atomic
number relative to other mentioned concretes (with exception of
barite concrete) is more effective shield.
Barite concrete with high density and effective atomic number
after steel magnetite is a useful concrete as a shield for building
construction of nuclear facilities as well. Simulation results for serpentine
concrete also indicated that it acts approximately similar
to ordinary concrete against gamma rays.
