Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radiation dose measuring card badge, which is a greatly improved film badge for measuring the personal exposure of personnel engaged in radiation work.

[0002]

2. Description of the Related Art Conventionally, a film sealed in an opaque bag is housed in a badge that also serves as a portable container, and a filter required for comparative measurement is brought into contact with both sides of the film. There is known a so-called film badge which is installed in a badge and an operator wears the badge when entering the radiation controlled area.

After a specific person has used a specific film badge for a certain period of time, it is collected, the film inside is taken out and developed, and the degree of exposure to radiation selected by a filter is measured, and it is used as various standards. The method of determining the work schedule of each individual is widely performed by measuring the amount of exposure of the individual during the period of use and centrally managing the obtained data of the individual's exposure.

The work of measuring the radiation dose using various devices such as film badges requires special specialized techniques, devices, experience, etc. for that purpose, and can be individually carried out at the work site dealing with radiation. Not a thing.

According to the method currently in use, a specific measuring company collects used film from the work site of a customer who handles radiation, supplies unexposed film to the work site, and develops the collected used film. The general procedure is to measure the exposure dose and report the measurement result to the customer.

At the work site where the unexposed film is supplied, the film is housed in a badge to be used by workers. The film bag has a user's name, code number, date, and film badge. A label on which necessary data such as a mounting position with respect to the body is printed is attached, and it is considered that a specific film is used by a specific individual in the worker at a specific mounting position for a specific period.

The badge portion of this type of film badge is made of synthetic resin so that it can be easily worn on workers' clothes.
It is provided with a mounting aid such as a clip or pin,
When a worker carries it, it is put in a pocket of the clothes as it is or attached to a predetermined position of the clothes by a clip for use.

Although the film of the film badge is consumed as a consumable item, the badge portion is repeatedly used by being sold to the customer by the measuring company or being lent to the customer by the measuring company, and is repeatedly used for a long time. Will be kept and managed.

[0009]

The film badge currently used has a volume of about 60 × 45 × 10 mm.
Since it is made of synthetic resin of a certain degree, it is necessary to store the film inside the badge for use as described above, and after using it, it is necessary to take the film out from the badge and send it to the measurement work. It is necessary to manage used and used films and badges, and to store a large number of badges requires some space.

Further, since the badge is repeatedly used for a long period of time, it is difficult to avoid deformation, damage, stain, etc. of the badge.
In addition, it is necessary to perform detailed management such as an unusable state due to damage to the badge attachment assisting means and replacement of the damaged attachment assisting means.

Regarding the film badges currently used, it is troublesome for the customer side to store and manage the film of the film badge, such as loading and unloading, and for the measuring company side, the transportation of the badge and the unit manufacturing cost of the badge. A considerable burden is inevitable in supplying missing badges, etc.

In view of the fact that these problems are caused by the volume and weight of the badge, the applicant of the present invention has repeatedly improved the badge portion in the past to provide a film badge as small and lightweight as possible. However, even with these improvements, the work of loading and unloading the film is necessary, the storage management on the customer side must be carried out as usual, and further improvements have been required in terms of price and ease of handling.

[0013]

[Means for Solving the Problems] In order to provide a film badge that is cheaper and easier to handle, in order to make the management part of the customer side easier by disposing the badge part of the conventional film badge. , Send the product of the present invention with the film loaded by the measuring company to the customer, leave only the management during use to the customer, and return it from the customer to the measuring company after use without taking out the film from the product of the present invention Do it.

As a result of pursuing a film badge that can be used in such a manner, the concept of a film badge that has been used in the past is departed, and a card is formed by polymerizing paper or a material similar thereto, and an accommodating hole is formed inside the polymerized card. Was reached, and a card badge for carrying the light-shielded film pack in the accommodation hole was reached.

Cardboard is most suitable as a material for forming a card badge, but it is also possible to use a cardboard together with a synthetic resin sheet.

The basic structure of a card badge is, for example, a bottom piece made of paper, and a main body made of cardboard having a receiving hole formed thereon is laminated and adhered, and a window is removed corresponding to the receiving hole to form a window. Overlap the perforated lid pieces. Further, if necessary, a transparent synthetic resin sheet may be attached thereon so as to cover the entire lid piece, or the bottom piece and / or the lid piece itself may be formed of a synthetic resin sheet. A pressure-sensitive adhesive is used to bond between the main body piece and the lid piece, and a release paper is partially placed between the main body piece and the lid piece so that the film pack can be freely inserted into the accommodation hole. .

Filters of the same shape made of metal, for example, are attached at positions in the accommodation hole where the bottom piece and the lid piece face each other, and necessary data are stored in the accommodation hole of the card badge having such a configuration. The unused film pack shown is inserted, the release paper between the lid piece and the main body piece is removed, the lid piece is pressure-bonded to the main body piece, and both are bonded to obtain a finished product.

The completed card badge is sent to the customer, carried by a worker engaged in radiation work, used for a certain period of time, and returned to the measuring company. The measuring company peels off the body piece to which the card badge is attached, takes out the film pack inside, and develops and measures the film. In the meantime, a new unused card badge has been sent from the measuring company to the customer, and the worker continues to carry and carry out measurements.

The quality of the bottom piece, the main body piece and the lid piece used as the material of the card badge can be arbitrarily selected. Especially, with respect to the main body piece, a ball in which fine paper or art paper is integrally formed on one side or both sides It is desirable to select paper. The reason is that it is easy to peel off the main body piece to which the card badge is attached. In addition, the number of main body pieces used for one card badge is arbitrary, and the thickness and number of main body pieces are determined according to the relationship between the thickness of the main body piece and the thickness of the film pack depending on whether the accommodation hole can be properly installed. To be done.

Further, the size, shape, number of filters and the like installed in the accommodation hole should be variously selected according to the type and intensity of radiation measured by the card badge of the present invention.

[0021]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the card badge of the present invention will be described with reference to the drawings. In FIG. 3, 1 is a bottom piece, 2 is a first body piece that is attached to the bottom piece 1 and has a first housing hole 3, and 4 is the same shape as the first body piece that is attached to the first body piece 2. The second housing hole 5 is provided in the second main body piece. Reference numeral 6 is a lid piece having a peep window 7 corresponding to the second accommodation hole 5, and is attached to each other by a pressure-sensitive adhesive placed between the second body piece 4 and the lid piece 6. However, the periphery of the accommodating hole 5 of the second main body piece 4 is covered with the release paper 8, and the adhesion of the both is blocked by the release paper 8 until the film pack 9 is inserted.

Reference numeral 10 denotes a transparent synthetic resin sheet which is laminated and attached to the lid piece 6, which prevents the surface of the lid piece 6 from being soiled, prevents dust from entering the viewing window 7, and cleans the inside. It is installed so that it can be seen. Reference numeral 11 denotes a filter installed on the bottom piece 1 and the lid piece 6 so as to face each other. The filter 11 is located in the first accommodation hole 3 and the second accommodation hole 5 and is inserted into these accommodation holes. The necessary parts of the are covered to partially shield the radiation.

In use, an unused film pack 9 is inserted into the first accommodation hole 3 and the second accommodation hole 5 formed by the first body piece 2 and the second body piece 4,
The release paper 8 is removed, and the second body piece 4 and the lid piece 6 are pressed against each other to bond them. As a result, the bottom piece 1, the first body piece 2, the second body piece 4, the lid piece 6 and the transparent synthetic resin sheet 10 form a card badge, and the first housing hole 3 and the second housing therein. A state in which the film pack 9 is housed in the internal cavity formed by the hole 5 is obtained.

The volume of the card badge of the present invention thus formed is about 50 × 80 × 2 mm, and the weight including the film pack 9 inside is about 6 g. It is used by putting it in the breast pocket of the worker's clothing, but if necessary, install a mounting aid device (not shown) such as a clip on an appropriate part such as the bottom piece 1 and attach it to any part of the clothing. You may allow it.

The card badge used for a certain period of time is returned from the customer to the measuring company. The measuring company can peel off the main body part of the card badge, take out the film pack 9 inside and send it to the developing treatment, and obtain the necessary measurement result from the film after the development is completed. The main body piece can be peeled off easily by inserting a fingernail into the thickness of the main body piece, but if necessary, a thin piece of synthetic resin or metal may be used instead of the nail. .

Also, in the embodiment, the film pack 9
It is explained that a sticker in which necessary data is written is attached to the surface of the device and the data is visually recognized through the viewing window 7, but the integral relationship between the film pack 9 and the card badge is guaranteed. In such a state, the viewing window 7 may be eliminated and necessary data may be written on the bottom piece 1 or the lid piece 6 or a written sticker may be directly attached. Further, depending on the situation, the film badge may have a structure in which the viewing window is simply abolished.

Further, the first body piece 2 and the second body piece 4
Is preferably made of paper so that the inner film pack 9 can be easily taken out. However, since the bottom piece 1 and the lid piece 6 do not have such a requirement, the bottom piece 1 and the lid piece 6 are made of synthetic resin. Also, a product equivalent to that of the above-mentioned embodiment can be obtained.

Also, the bottom piece 1, the main body piece 2 and / or 4,
Of course, if it is possible to secure the mutual fixing and separation of the lid pieces 6, it is of course possible to manufacture some or all of these with materials other than paper (for example, synthetic resin).
