DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radiation measurement data processing system, and more particularly to a radiation measurement data processing system in a nuclear facility such as a nuclear power plant requiring radiation management.

[0002]

2. Description of the Related Art Conventionally, in nuclear facilities such as a nuclear power plant, radiation measurement and management are carried out by bringing a radiation measuring instrument and a recording sheet to a measurement place, and recording the measured dose equivalent rate in a form corresponding to the measurement place. A radiation management record creation method is adopted in which the recording paper is taken out of the management area and is transferred to the radiation management record. In addition, a method is also used in which a storage medium is attached to a radiation measuring instrument instead of recording paper, and the dose equivalent rate is recorded together with measurement location information (for example, a number) on the storage medium, and radiation is managed and recorded. Further, radiation dose measurement is performed by inputting the dose equivalent rate measured in a mesh form by key input or mouse input, and creating the dose equivalent rate by computer processing. In addition, Japanese Unexamined Patent Publication
JP-A-120686 discloses that radioactive dust is detected from dust collected on a collection sheet, a mark indicating a measurement number is attached to the collection sheet, and this marking corresponds to radiation data at a measurement location. A technique for causing this to occur is disclosed.

[0003]

However, since a work area is divided into a large number in a nuclear power plant, a radiation management record is created for each work area. In addition, since the radiation measurement for creating the dose equivalent rate distribution map and the like is required to be performed at the same time or on the same day, the number of measurement points measured at the same time is approximately 50.
There may be zero or more places. Under such circumstances, in the conventional radiation management record creation method, the measurement is performed by two measurers and two loggers due to measurement and the like, so that a large amount of time is required for the measurement record. Also, because the recording paper is taken out of the control area and radiation measurements are recorded for each recording paper, it takes a lot of time to take necessary measures for implementation. There is a problem that it takes time or that it takes time to create a radiation management record by hand.
Further, in the method of managing and recording radiation by a radiation measuring instrument having a storage medium, measurement location information (for example,
It is necessary to carry out a drawing etc. with measurement location information and carry out measurement according to the order, or to perform measurement operation after selecting measurement location information for each measurement location. In the former, the radiation measurement is performed in parallel with the work, so it is difficult to measure according to the order of the measurement location information, and there is a lot of wasteful work.In the latter, the operation of selecting the measurement location information takes time. is there. In addition, although there is software that creates dose equivalent rates based on dose equivalent rates measured in a mesh, the value of the dose equivalent rate is manually entered,
There are problems such as erroneous input and input time. In addition, the technology described in the official gazette is a method in which the measurement target is switched by a sample tube and radiation is detected by a collection paper for collecting dust. And radiation data
Since no consideration has been given to the management of data, there is a problem that the measurement location and the radiation data cannot be made to correspond at a glance and quickly. SUMMARY OF THE INVENTION An object of the present invention is to provide a radiation measurement data processing system that executes processing from radiation measurement to radiation management recording quickly, efficiently and with high reliability in view of the circumstances of the related art. .

[0011]

As described above, according to the present invention,
Before starting the measurement, the measurement place to be described on the drawing of the radiation management record is determined and converted to a bar code and output at the same time, and the measurement place of the radiation management record and the actual measurement place are pasted to the measurement place. Can be matched via a bar code. In addition, the radiation measuring device and the bar code reader are integrated, and the radiation is measured by the radiation measuring device together with the reading of the bar code, and recorded in correspondence with the bar code information. Accordingly, it is possible to make the measurement location and the measurement value coincide with each other via a bar code, thereby eliminating a recording error and shortening the measurement recording time.
Also, by adopting a storage medium such as an IC card as the information transmitting means, it is possible to greatly simplify the taking out of the measurement data from the management area and to simplify the input for preparing the radiation management record. It becomes possible to plan. Further, since the measurement location of the data on the storage medium and the measurement location of the radiation management record coincide with each other via the bar code, the creation of the radiation management record is simple and reliable. As described above, in the processing from the measurement of radiation to the output of the radiation management record, it is not necessary to manually transfer the measurement data and key input, and the work time is shortened and the reliability is remarkably improved.
