FIG. In the following description, the elapsed time is adopted as the time data, and the elapsed time is measured by the data processing terminal 22. As the time data, in addition to the elapsed time, the measurement time of the individual exposure dose and the current time can be adopted. It is assumed that a sketch (image) of a work location is transmitted from the management terminal 14 to the data processing terminal 22 using a wireless LAN.

  The management terminal 14 generates visualization information obtained by adding (synthesized) the elapsed time and the planned set value to the individual exposure dose data, and displays the visualization information on the display 38 (visualization information second display means). Further, the sound collected by the microphone 20 is output from a speaker connected to the management terminal 14 (sound output means). As shown in FIG. 6, the display 38 displays a time data display area 6a (month, day, hour, minute and second) indicating the elapsed time from when the worker 12 enters the work area until the present time in the work area. The dose equivalent rate display area 6b (mSv / h) displaying the dose equivalent rate, the individual exposure dose displaying the individual exposure dose, the display area 6c (mSv), and the plan set value display area 6d (mSv) displaying the plan set value / H), personal identification data display area 6e displaying personal identification data (name, age, gender, department, email address) of worker 12, photo display area 6f displaying photograph of worker 12, work A work location image display area 6g displaying a sketch (image) of the location is displayed.
