title: Gamma radiation transmission along the multibend mazes.
abstract: Installing a maze on the corridor reduces much shielding materials in shielding door at the end of the pathway. In this study, gamma transmission was measured along single-, double-, and triple-bend mazes, which were applied to nondestructive test workplace by Monte Carlo method. In the facility using (192)Ir 1.85TBq, the lengths of corridors to reduce the effective dose under the limitation without shielding door were 10 and 6m in double- and triple-bend mazes, respectively.
