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.
