摘　　要：The aging test of multigap resistive chamber (MRPC) was carried out under conditions of irradiation from a 137Cs γ source facility. The total charge induced at the anode or at the cathode of the MRPC module was about 29 mC. The gamma dose rate was 10-2 Gy·h-1, and the total accumulative radiation dose was 4.3 Gy. After irradiation, there was an obvious degradation in the properties of the MRPC module.The aging test of multigap resistive chamber （MRPC） was carried out under conditions of irradiation from a ^137Cs γ source facility.
