simulation package were obtained using the FLUKA Monte Carlo code at 59.5, 80.9, 140.5,
356.5, 661.6, 1173.2 and 1332.5 keV photon energies. The results for the mass attenuation
coefficients obtained by simulation have been compared with experimental and the
theoretical ones and good agreement has been observed. The results indicate that this
process can be followed to determine the data on the attenuation of gamma-rays with the …
