To obtain cobalt target activity data after a cycle of irradiation in a pressurized water reactor,the cobalt target dose distribution was measured underwater using alanine dosimeters.The effects of cobalt target structure,water medium,measurement device,operation,and environment were corrected using Monte Carlo calculations.The feasibility of the method and device was confirmed through both experimental and Monte Carlo comparison.The underwater measurement data of cobalt target activity matches the theoretical calculated values,with an uncertainty of 6.5％.
