The plan set value can be arbitrarily set by the input device. Although not shown, there are cases where the controller 23 and the data processing terminal 24 are accommodated in a shoulder bag worn by the worker 11 and are carried along with the shoulder bag.

  The personal exposure dosimeter 25 measures the personal exposure dose data of the worker 11 at predetermined time intervals. The measurement time (for example, the interval of 3 seconds or the interval of 10 seconds) in the personal exposure dosimeter 25 can be set arbitrarily. The individual exposure dose data is an individual exposure dose (mSv or μSv) and a dose equivalent rate (mSv / h or μSv / h).
