A duct streaming method for leakage from ducts penetrating the shielding wall from inside the maze to outside the room, which is necessary for the shielding design of a medical linac room for cancer treatment, was studied. We calculated the effective doses leaking from the ducts by using a three-dimensional Monte Carlo code MCNP5 and compared with the duct streaming method.
