Abstract
In order to validate dose evaluation methods for radiation shielding design of accelerator facilities, absorbed dose distributions in a plastic phanto m of 30 x 30 x 30 cm(3) slab were measured for 40- and 65-MeV quasi-monoene rgetic neutrons with a tissue-equivalent proportional counter and a tissue- equivalent ionization chamber. The measured distributions were compared wit h the calculated ones from the energy deposition of charged particles and n eutron energy spectra by using the Monte Carlo codes, HETC-3STEP and MORSE- CG/KFA, respectively. As a result, it was revealed that the calculation met hod used in the present work was applicable to absorbed dose evaluation for intermediate energy neutrons with high accuracy.
