The invention relates to a method for monitoring and predicting the state of equipment personnel based on a nuclear power plant access monitoring system. According to the method, a nuclear power plantautomatically uploads radiation measurement result information and equipment running state information to a central control system; and a personal dosage monitoring equipment of the nuclear power plant automatically uploads personal dosage information and equipment running state information to the central control system. The central control system processes the equipment running state informationof pollution monitoring equipment and the personal dosage monitoring equipment according to a preset equipment analysis model, and realizes current health state evaluation, running parameter dynamicadjustment, state monitoring and preventive maintenance strategy formulation of each equipment; and the central control system processes personal dosage information according to a preset personal behavior analysis model, and realizes work allocation, high-risk population identification, differentiation management and personalized pollution monitoring, thereby improving the management level of theradiation of the nuclear power plant.
