Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a body surface monitor device for monitoring radioactive contamination on the body surface used in a nuclear facility.

[0002]

2. Description of the Related Art In a nuclear facility, a body surface monitoring device is installed at the entrance of a building of the nuclear facility, and this body surface monitoring device detects radioactive contamination on the human body surface at the boundary of the radiation control area, thereby ensuring the safety of workers of the facility. Has been secured.

In recent years, facilities such as nuclear power plants have become large in scale, and it is necessary to measure in a short time that there is no whole body radioactive contamination of a large number of workers. A device has been developed which can fully and automatically measure the whole body radioactive contamination of the worker when he / she exits after finishing the work in.

In this case, as a measurement operation, if the worker 102 stands in front of the body surface monitor device 101 as shown in FIG.
Is detected, the entrance side door 103 is opened, and when this worker 102 enters the inside, the entrance side door 103 is closed and the degree of contamination on the body surface is measured. When the side door 104 is opened and the worker 102 goes out, the exit side door 104 is closed.

[0005]

By the way, the above-mentioned conventional body surface monitoring device 101 has the following problems.

That is, such a body surface monitoring device 1
Since 01 has only a single function for measuring body surface contamination as exit control after the end of work, other items included in the same exit control items, such as external exposure dose during work, can be measured. When recording the data, a measuring device other than the body surface monitoring device 101 must be used.

Also, when performing an ID check, which is an item of entry control, it is necessary to use a measuring device different from the body surface monitoring device 101, which is troublesome. At the same time, there was a problem of being inefficient.

[0008] In such a nuclear facility, a health check is conducted at the stage of entry procedure in advance.
Since such a medical checkup, such as blood pressure measurement, is performed individually, there is a problem that the entrance procedure takes time.

In view of the above-mentioned circumstances, the present invention enables ID confirmation and blood pressure measurement at the time of entry before work, and dose exposure during work and body surface contamination measurement at the time of exit after work. It is an object of the present invention to provide a body surface monitoring device that can be used in both directions of entry and exit to significantly improve examination efficiency.

[0010]

In order to achieve the above object, the present invention provides a gate monitor housing arranged between a management area side and an external area side, and the management area side of the gate monitor housing. In the body surface monitor device having an entrance / exit door provided on each side of the door and the outside area and various measuring devices arranged in the gate monitor enclosure, when the entrance mode is set, the entrance / exit door of each entrance / exit door Of these, the entrance door on the external area side becomes the entrance door, and the entrance door on the management area side becomes the exit door, allowing the subject to enter and exit the gate monitor enclosure, and the measurement processing and verification processing necessary for entrance processing. And when it is in the exit mode, the entrance door on the management area side becomes the entrance door among the entrance doors, and the entrance door on the outside area becomes the exit door,
While moving the subject in and out of the gate monitor
It is characterized by performing the measurement processing and collation processing necessary for the exit processing.

[0011]

In the above structure, when the entrance mode is set, the entrance door on the external area side becomes the entrance door and the entrance door on the management area side becomes the exit door among the entrance / exit doors. While the subject is moved in and out of the enclosure, the measurement and verification processes necessary for entrance processing are performed, and when the exit mode is set, the entrance door on the control area side is the entrance door. Next to
The entrance door on the external area side serves as an exit door that allows the subject to enter and exit the gate monitor housing, and also performs the measurement and verification processing required for exit processing to confirm the ID before entering the work area. The blood pressure is measured, and the radiation dose during work and body surface contamination are measured at the time of leaving the area after the work, so that the examination efficiency can be greatly improved by using it both in and out.
