Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an exposure management system, and more particularly to exposure management for workers engaged in work in a radiation handling facility.

[0002]

2. Description of the Related Art In a radiation handling facility such as a nuclear power plant, a nuclear fuel processing facility, a radiation medical facility, etc., personal exposure control of each worker is indispensable. In particular, there is a demand for a system that can manage the exposure of each worker in real time.

Japanese Patent Application Laid-Open No. 11-248839 discloses a conventional exposure management system. This conventional system has a plurality of portable devices carried by a plurality of workers in a radiation handling facility and a host device for collecting data from the plurality of portable devices. The radiation handling facility is divided into a plurality of areas (for example, one room corresponds to one area). One base station is installed in each area, and wireless communication is performed between the plurality of base stations and the plurality of portable devices. The plurality of base stations are connected to the host device via a communication line. Each mobile device has a call function according to a cellular telephone system such as PHS and radiation measurement (exposure dose measurement).
With function. The dose data wirelessly transmitted from the portable device is received by the base station installed in the area (affiliation area) where the portable device is present, and the received dose data is transmitted to the host device. The host device determines the area to which the portable device belongs by determining the base station that received the dose data. In the host device,
The exposure dose and assigned area are managed for each worker. Further, devices such as an area monitor and a dust monitor installed in the radiation handling facility are connected to the host device. When the host device determines any radiation abnormality, an alarm signal is transmitted from the host device to some or all of the portable devices. An alarm message is displayed and the vibrator is activated in the portable device that has received the alarm signal.

[0004]

However, in the above-mentioned conventional system, the information transmitted from a plurality of portable devices is collected and centrally managed by the host device, but the information collected in such a manner (or The information generated by processing it) is, except for the above alarm signal,
There is no feedback to each worker. In other words, the information provided to each worker is not sufficient.

Specifically, in the above conventional system, information (alarm signal) is provided only in the case of an abnormality, but it is desirable to actively provide the information even in the normal state. Further, in the above-mentioned conventional system, only the fact of abnormality is provided to each worker as an alarm signal, and information regarding the present condition (or the condition around oneself) in the radiation handling facility is not provided. . Furthermore,
It can be pointed out that in the above-mentioned conventional system, the position of each worker is too roughly specified. In addition, in the above-mentioned conventional system, each worker cannot obtain any information regarding the exposure status of other workers except himself at the work site, and therefore, the workers cannot manage the exposure to each other, and There was a possibility that other workers could not be sufficiently cared for in an abnormal condition.

[0006] By the way, the work in the radiation handling facility gives a great mental stress to the worker depending on its contents. In addition, when an abnormality occurs, each worker needs to calmly deal with the abnormality, so it is desirable to objectively judge whether each worker is in a mental panic state. Be done. However, an exposure management system capable of managing the health (mental) condition of each worker in real time has not yet been provided.

As a patent application relating to exposure management, there is Japanese Patent Application No. 11-326481 (filing date: November 17, 1999).

The management device acquires position information and dose information from the personal dosimeter and also acquires imaging data. Here, the management device has various alarm determination functions. When an alarm is determined, an alarm signal is output from the management device to the personal dosimeter. However, even in the system disclosed in this patent application, the above-mentioned JP-A-11-
The same problem as the system disclosed in Japanese Patent No. 248839 can be pointed out, that is, it cannot provide sufficient information to each worker.

The present invention has been made in view of the above conventional problems, and an object thereof is to provide a worker with useful information for exposure control.
