This paper gives a theoretical calculating method for the dose rate of the maze of the low-energy accelerators or high-energy accelerators,based on the NCRP report Nos.49,51 and 151.The multi-legged maze of the Miyun CT workshop of the NUCTECH Company Limited and the arc maze of the radiation laboratory of the Academy of Military Medical Sciences were calculated using this method.The calculating results were compared with the MCNP simulating results and the measured results.For the commonly estimation of the maze dose rate,as long as the parameters chosen properly,this method can give a conservative result,and save time from simulation.It's hoped that this work could offer a reference for the maze design and the dose estimation method in the aftertime.
