In this paper, the Monte Carlo method is used to calculate the dose distribution in a60Co container inspection hall with and without scatterers. Firstly, the results calculated withoutany scatherers are compared with the experimental measuring data and it shows that our physicalmodel is correct and reasonable. Then, calculations about polythene and iron board scattererswith two kinds of thickness were carried out. Having analysing the calculation results. The im-pact of the scattered photon on the dose rate in the hall was discussed. The results show that theradiation safety of the 60Co container inspection system is excellent.
