摘要
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 Ir-192 1.85 TBq, the lengths of corridors to reduce the effective dose under the limitation without shielding door were 10 and 6 m in double- and triple-bend mazes, respectively.
