Implementation of FLUKA for gamma-ray applications in the marine environment

摘要

The FLUKA code was implemented to simulate pulse-height spectra of a NaI(TI) detector (excluding its resolution), considering radioactive sources of naturally occurring and artificial radionuclides present in the marine environment. For this purpose, a user-defined routine was developed for the proper simulation of the emitted gamma-rays. The results were compared with simulations performed using the MCNP-CP code. The comparison of the recorded counts in the full-energy peaks, for the high intensity (emission probability >15%) emitted gamma-rays for each radionuclide, yielded a satisfactory agreement (calculated ratios from 0.93 +/- 0.05 to 1.07 +/- 0.02) in all the studied cases.
