A computer system for dose assessment was installed to evaluate radiation dose of each worker in a controlled area and to automatically produce reports on dose assessment. The main computer was connected to both a tritium monitor control computer and a gate control computer. This computer network has been isolated from a public network. The gate control computer registers data on working hours of each worker in the controlled area and on tritium concentration of each room. The dose assessment computer acquires essential data from the gate control computer to evaluate the radiation dose of each worker. The potential of the specialized network system to improve dose assessment was examined over a period of two years. It was found that this system significantly contributed to improvement of dose assessment. The basis of assessment was made clear, and reports on dose assessment without errors were readily produced.
