Description

[Detailed description of the invention] This invention relates to a container for monitoring equipment that measures radiation within a controlled area in nuclear power related facilities.

Examples of monitoring devices used to evaluate the external exposure dose of individuals in controlled areas include pocket dosimeters, film badges, and thermoluminescent dosimeters (TLD). Each wearer uses the device by storing it in the pocket of their clothing or protective clothing. Therefore, not only do the wearing positions differ depending on the individual differences of each wearer, but also the various monitoring devices may overlap and interfere with each other in the pocket, causing an underestimation of the measured value, or may come into contact with each other or be dropped. This may cause damage or malfunction. Moreover, since each monitoring device is handled independently in this way, it is troublesome to handle, such as forgetting to put it on or losing it in some cases, and moreover, it has drawbacks such as being easily soiled.

This idea was devised based on the above circumstances, and its purpose is to prevent mutual interference between monitoring devices, protect them and improve the reliability of incident radiation measurement results, and to integrate all monitoring devices at once. It is an object of the present invention to provide a radiation monitoring equipment container that can be handled with ease and can prevent loss or forgetting to wear it.

This invention will be explained below based on an illustrated embodiment. In the figure, 1 is a monitoring equipment container, and 2 is its main body. This main body 2 is made of a radiolucent material, such as a flammable and easily processed material such as a polyethylene sheet. ing. And in the main body 2,
Bag-shaped housing portions 3, 4, and 5 also made of a radiolucent material are formed. Each of these housing parts 3,
4 and 5 are monitoring equipment that should be stored respectively.
The shape and size are formed according to A ₁ , A ₂ , and A ₃ . As an example of the monitoring devices A ₁ , A ₂ , A ₃ , A ₁ is a pocket dosimeter, A ₂ is a thermoluminescence dosimeter, and A ₃ is a film band. And each housing section 3, 4, 5 is for each monitoring device.
A ₁ , A ₂ , and A ₃ are arranged independently and adjacent to each other in a plane so that they do not overlap. In addition, the ejection ports 3a and 4a of the housing parts 3 and 4 for devices that are frequently taken out and put in, such as pocket dosimeter _A1 and thermoluminescence dosimeter _A2 , are also provided.
is covered by a top cover 6 that can be opened and closed so that internal equipment can be taken in and out easily. This upper cover 6 can be fixed to the housing portion 4 using a fastening device 7 such as a so-called magic tape (trade name) or a hook. In addition, the accommodation section 5 for equipment such as the film board _A3 that is not taken out frequently and that requires protection from high humidity, acid, alkali, etc., is sealed. Also,
Insertion holes 8, 8 are formed in the upper part of the main body 2, and a hanging string 9 for hanging around the neck is inserted through the insertion holes 8, 8.

The radiation monitoring device housing 1 configured as described above can be stored in the inner pocket of protective clothing while wearing protective clothing in a controlled area, and can be stored using the hanging string 9 at other times. and wear it to monitor radiation. And frequently used pocket dosimeter A ₁ , thermoluminescent dosimeter
Each time A ₂ is used, it is taken out from each storage section 3 and 4 and the radiation is measured. On the other hand, after several weeks or a month have elapsed, the film badge _A3 is removed from the container 5 by unsealing it, developed, and subjected to radiation type identification and dose measurement. After removing the film badge A ₃ , the monitoring equipment container 1 is disposed of by incineration. In addition, the above-mentioned film badge accommodating part 5
Like the other storage units 3 and 4, the storage unit 1 has a structure that allows film badges to be taken in freely.
Of course, it may be possible to use it repeatedly.

However, according to the above embodiment, the monitoring devices A ₁ , A ₂ , and A ₃ are accommodated in a flat manner without overlapping each other, so that these devices may interfere with each other and cause measurement errors, or may come into contact with each other. This prevents damage and malfunction caused by dropping or falling. In addition, since each monitoring device can be handled at once,
You can prevent each device from being lost or forgotten to wear. Moreover, according to this embodiment, the film badge A ₃ is sealed in the housing part 5, so it can be used as is even in high humidity, acid, alkali, tritium gas, etc. atmospheres, or in places that are easily contaminated. Yes, the usage conditions are relaxed. Furthermore, since the hanging string 9 is used to hang the device around the neck, it is possible to keep each monitoring device in the same position regardless of individual differences among the wearers. Beneficial.

Note that the monitoring device is not limited to the above-mentioned examples, and of course may be a pocket ionization chamber, a glass dosimeter, an alarm meter, or other devices. The formed accommodating parts may be arranged so that the respective devices do not overlap with each other, and the specific configuration such as the number and shape thereof can be modified in various ways.

As mentioned above, according to this invention, each monitoring device is stored in the storage section and handled as a unit, which not only prevents each device from being lost or forgotten to wear, but also prevents the devices from being overlapped. Since each device is accommodated without interference, it is possible to prevent each device from interfering with each other and causing measurement errors, and the reliability of measurement results is improved. Moreover, damage and malfunction due to mutual contact or falling can be prevented. In addition, since each monitoring device can be stored in a predetermined position, it is possible to standardize the wearing position of each device, and since each device is covered by the storage section, it can be prevented from getting dirty. be effective. Monitoring equipment that is frequently taken out is housed in the first storage part whose upper opening can be opened and closed with a cover, and monitoring equipment that is taken out frequently and needs to be protected from the external atmosphere is housed in the second storage part. Since the device is housed in the storage section in a sealed state, it is easy to handle devices that are frequently taken out, and devices that need to be protected from the external atmosphere can be effectively protected.
Furthermore, since it can be hung using a hanging string, it is not only easy to handle, but also the wearing position is constant, making it possible to standardize measurement conditions.
