Abstract: Based on the requirements of occupational internal exposure monitoring technology in nuclear power plants, and combined with the actual work of a nuclear power plant, an automated measurement system for whole body counter (WBC) of occupational internal exposure has been developed for nuclear power plants. By partitioning the design of the monitoring laboratory and adding multiple systems such as self-service reservation system, access control system, automated measurement system, acoustic and visual signal guidance system on the traditional whole body counter measurement equipment, and interacting with the data from the personal dose management platform of nuclear power plant, a whole process of self-service operation for the measured personnel is realized. This innovation makes up for the shortcomings of manual operation in traditional equipment, which effectively reduces the manpower demand and risk of human error in monitoring personal internal exposure doses in nuclear power plants, and promotes the localization of measurement equipment.

Key words: occupational internal dosimetry, whole body counter, automatic measurement, dose estimation
