We review some accelerator benchmark experiments on source term and radiation shielding conducted by JAEA to validate the accuracy of the radiation behavior simulation code such as PHITS code. (1) Neutron spectra measurement from thin beryllium target bombarded with about 10 MeV protons for accelerator boron neutron capture therapy. (2) Forward direction neutron spectra measurements and shielding experiments from beryllium target bombarded with 140, 250 and 350 MeV protons. (3) Neutron spectra measurement from tungsten target bombarded with about 400 MeV protons for the establishment of irradiation field for semiconductor tests. (4) Shielding experiments at Pbar target station and NuMI target station of Fermi Lab.
