Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an exposure management system, and more particularly to exposure management of workers engaged in work in a radiation handling facility.
[0002]
[Prior art]
In radiation handling facilities such as nuclear power plants, nuclear fuel processing facilities, and radiation medical facilities, it is essential to manage the individual exposure of each worker. In particular, there is a demand for a system that can manage the exposure of each worker in real time.
[0003]
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 that collects 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 a plurality of base stations and a plurality of portable devices. The plurality of base stations are connected to the host device via a communication line. Each portable device has a telephone call function according to a cellular telephone system such as PHS, and a radiation measurement (exposure dose measurement) 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 exists, 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 has received the dose data. In the host device, the exposure dose and affiliation area are managed for each worker. The host device is connected to devices such as an area monitor and a dust monitor installed in the radiation handling facility. When the host device determines any radiation abnormality, an alarm signal is transmitted from the host device to some or all portable devices. In the portable device that has received the alarm signal, an alarm message is displayed and the vibrator is activated.
[0004]
[Problems to be solved by the invention]
However, in the above-described conventional system, information transmitted from a plurality of portable devices is collected by the host device and centrally managed. However, information collected in this manner (or information generated by processing the information) is collected. ) Is not fed back to each worker except for the alarm signal described above. In other words, providing information to each worker is not sufficient.
[0005]
Specifically, in the conventional system, information (alarm signal) is provided only in the case of an abnormality, but it is desirable to actively provide information even in a normal state. Further, in the above-described conventional system, only the fact of abnormality is simply provided as an alarm signal to each worker, and no information on the current state (or surroundings) in the radiation handling facility is provided. . Furthermore, it can be pointed out that the position of each worker is too rough in the conventional system. In addition, in the above-described conventional system, each worker cannot obtain any information regarding the exposure state of other workers other than himself / herself at the work site, and therefore cannot perform exposure management between workers, There was a possibility that other workers could not be fully cared for in the event of an abnormality.
[0006]
By the way, the work in the radiation handling facility gives a great mental stress to the worker depending on the contents. In addition, when an abnormality occurs, each worker needs to cope with the abnormality calmly, so it is desirable to objectively determine whether each worker is in a mental panic. It is. However, an exposure management system that can manage the health (mental) status of each worker in real time has not yet been provided.
[0007]
In addition, there is Japanese Patent Application No. 11-326481 (application date: November 17, 1999) as a patent application relating to exposure management.

The management device acquires position information and dose information from the personal dosimeter, and acquires imaging data. Here, the management apparatus 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 same problem as the system disclosed in the above-mentioned Japanese Patent Application Laid-Open No. 11-248839 can be pointed out, that is, sufficient information cannot be provided to each worker. .
[0008]
