Description
本開示は、放射線遮蔽板に関する。 The present disclosure relates to a radiation shield.
従来、病院のレントゲン室などの医療施設や、研究施設、あるいは原子力発電所など放射線を取り扱う施設では、壁材などに放射線の遮蔽性能を有する板材が用いられている。
このような放射線を遮蔽する壁材としては、鉛などの金属やコンクリートがよく知られているが、この他に、放射線の遮蔽性を有した樹脂を用いたものも知られている（例えば、特許文献１、特許文献２）。
これらの従来技術では、樹脂に放射線の遮蔽性を有した金属粉を含有させたものが用いられている。
BACKGROUND Conventionally, in medical facilities such as a radiography room of a hospital, research facilities, or facilities handling radiation such as a nuclear power plant, a plate material having a radiation shielding performance is used as a wall material.
As a wall material for shielding such radiation, metal such as lead and concrete are well known, but in addition, those using a resin having radiation shielding properties are also known (for example, Patent Document 1 and Patent Document 2).
In these conventional techniques, resins containing metal powder having radiation shielding properties are used.
しかしながら、上述の従来技術では、放射線の遮蔽性を有した樹脂を新たに製造する必要があり、既存の樹脂板を用いることができず、汎用性に劣る。また、放射線の遮蔽性を有した汎用樹脂とは異なる樹脂を製造する必要があり、新たな設備投資が必要である。 However, in the above-mentioned prior art, it is necessary to newly manufacture a resin having a radiation shielding property, the existing resin plate can not be used, and the versatility is inferior. In addition, it is necessary to manufacture a resin different from general-purpose resin having radiation shielding properties, and new capital investment is required.
また、壁材として、鉛などの金属板を用いる場合は、その重量が重く施工性に劣る。また、壁材としてコンクリートを用いる場合は、コンクリートの流し込み作業となるため、板材を用いる場合と比較して、施工性に劣り、しかも、劣化によるひび割れなどにより放射線の遮蔽性低下のおそれがある。しかも、既存の建物において、後から放射線の遮蔽性を与える部屋を形成するのが難しく、この点でも施工性に劣る。 Moreover, when using metal plates, such as lead, as a wall material, the weight is heavy and it is inferior to workability. In addition, when concrete is used as a wall material, concrete is poured into the work, and therefore the construction is inferior to the case where a plate material is used, and there is also a possibility that the radiation shielding property may be deteriorated due to cracking due to deterioration. In addition, in existing buildings, it is difficult to form a room that provides shielding of radiation later, and this is also inferior in workability.
本開示は、上記問題に着目してなされたもので、汎用性および施工性に優れる放射線遮蔽板を提供することを目的とする。 This indication is made paying attention to the above-mentioned problem, and it aims at providing a radiation shielding board which is excellent in versatility and construction.

を備える放射線遮蔽板とした。

本開示の放射線遮蔽板は、板材に、放射線の遮断性を有した金属メッキ層を設けた金属板を積層するだけで、製造することができる。したがって、既存の板材や、金属メッキ金属板を用いることができ、汎用性に優れる。加えて、板材により形状保持可能であるため、金属板に形状保持性能を与える必要が無く、金属板の板厚を抑え、軽量化を図ることが可能である。
しかも、放射線遮蔽板は、板状を成すため、コンクリートによって壁を構築する場合と比較して、施工性に優れる。

さらに、金属メッキ層を、前記金属板の表裏両面に設けたものでは、金属メッキ層を金属板本体の表裏面の一方のみに設けたものと比較して、放射線遮蔽性能を向上できる。
The radiation shielding board of this indication can be manufactured only by laminating | stacking the metal plate which provided the metal plating layer which had the shielding property of the radiation on the board | plate material. Therefore, the existing board material and a metal plating metal plate can be used, and it is excellent in versatility. In addition, since the shape can be maintained by the plate material, it is not necessary to provide the metal plate with shape maintaining performance, and the thickness of the metal plate can be suppressed to achieve weight reduction.
Moreover, the radiation shielding plate has a plate-like shape, and thus is excellent in workability as compared with the case of constructing a wall with concrete.
In addition, while what made the metal plating layer the tin plating layer can use a cheap thing using what is called an easy manufacturing method, such as soaking, many existing products are also excellent, and also it is excellent in versatility.
Moreover, when the thickness of the said tin plating layer is 25 micrometers or less, high radiation shielding performance can be obtained, ensuring productivity.
Furthermore, in the case where the plate material is made of a foamed resin, the weight of the radiation shielding plate can be further reduced.
Moreover, while what can use the said metal plate as a steel plate can aim at the improvement of shape retention performance, it is possible to aim at the improvement of versatility.
And in the thing which laminated | stacked the said metal plate on front and back both surfaces of the said board | plate material, a radiation shielding performance can be improved compared with what provided the metal plate in only one of front and back of board material.
Furthermore, in the case where the metal plating layer is provided on both the front and back sides of the metal plate, the radiation shielding performance can be improved as compared with the case where the metal plating layer is provided on only one of the front and back sides of the metal plate main body.
以下、本開示の放射線遮蔽板を実現する形態を、図面に示す実施の形態に基づいて説明する。
（実施の形態１）
以下、実施の形態１の放射線遮蔽板Ａについて説明する。
（放射線遮蔽板の構成）
まず、実施の形態１の放射線遮蔽板Ａの構成について説明する。
図１は、実施の形態１の放射線遮蔽板Ａの断面図である。
図１に示すように、放射線遮蔽板Ａは、板材１０と、この板材１０の表面１０ａおよび裏面１０ａに積層された金属板としての鋼板２０を備える。
Hereinafter, a mode for realizing the radiation shielding plate of the present disclosure will be described based on an embodiment shown in the drawings.
Embodiment 1
Hereinafter, the radiation shielding plate A of Embodiment 1 will be described.
(Structure of radiation shielding plate)
First, the configuration of the radiation shielding plate A of the first embodiment will be described.
FIG. 1 is a cross-sectional view of the radiation shielding plate A of the first embodiment.
As shown in FIG. 1, the radiation shielding plate A includes a plate 10 and a steel plate 20 as a metal plate stacked on the front surface 10 a and the back surface 10 a of the plate 10.
板材１０は、例えば、ポリエチレン、ポリプロピレンなどの発泡樹脂により板状に形成されたものを用いている。その寸法は、縦横寸法が1800〜2000cｍ×90〜100cｍ程度の建築用の板材としての一般的な寸法に形成され、厚さは、2.0〜20.0ｍｍ程度の寸法に形成されており、一例として、2.5ｍｍの厚さとする。この板材１０は、後述する板厚が薄い剛性の小さい鋼板２０の板状の形状を維持するためのものであり、その機能を確保できれば厚さは問わない。 For example, the plate member 10 is formed of a foamed resin such as polyethylene or polypropylene in a plate shape. The dimension is formed in a general dimension as a plate material for construction having a vertical and horizontal dimension of about 1800 to 2000 cm × 90 to 100 cm, and a thickness is formed to a dimension of about 2.0 to 20.0 mm. The thickness is 2.5 mm. The plate material 10 is for maintaining the plate-like shape of the small rigid steel plate 20 having a small plate thickness, which will be described later, and the thickness is not limited as long as its function can be ensured.
鋼板２０は、板材１０の表裏面１０ａ，１０ａの全面を覆う寸法を有し、かつ、板厚が1.0ｍｍ程度の薄板状のものであり、鋼板本体２１とその外周に設けられた金属メッキ層としての錫メッキ層２２とを有している。
鋼板本体２１は、本実施の形態１では、厚さが0.7〜0.8ｍｍ程度の寸法のものを用いている。
The steel plate 20 has a dimension to cover the entire front and back surfaces 10a and 10a of the plate member 10, and is a thin plate having a plate thickness of about 1.0 mm, and the steel plate main body 21 and a metal plating layer provided on the outer periphery thereof. And a tin-plated layer 22.
In the first embodiment, the steel plate main body 21 has a thickness of about 0.7 to 0.8 mm.
錫メッキ層２２は、鋼板本体２１を、錫の溶融した溶融金属中に浸漬させるメッキ、いわゆるドブ漬けにより形成されたもので、鋼板本体２１の外側面の全体に亘って設けられている。また、本実施の形態１では、錫メッキ層２２の厚さは、20〜25マイクロメートル（以下、μｍと表す）程度であり、例えば、23μｍとする。 The tin plating layer 22 is formed by plating in which the steel sheet body 21 is immersed in molten metal in which tin is melted, so-called dip coating, and is provided over the entire outer surface of the steel sheet body 21. Further, in the first embodiment, the thickness of the tin plating layer 22 is about 20 to 25 micrometers (hereinafter referred to as μm), and is, for example, 23 μm.
（実施の形態１の作用）
次に、実施の形態１の放射線遮蔽板Ａの作用を説明する。
（放射線遮蔽性能）
まず、放射線の遮蔽性能について説明する。
JIS Z4501 X線防護用品の鉛当量試験方法に準拠して、Ｘ線に対する遮蔽性が何ｍｍ厚の鉛に相当するのかを評価し、０．２ｍｍ相当の遮蔽性能を有することが分かった。
(Operation of Embodiment 1)
Next, the operation of the radiation shielding plate A of the first embodiment will be described.
(Radiation shielding performance)
First, radiation shielding performance will be described.
According to the lead equivalent test method of JIS Z4501 X-ray protective article, it was evaluated that the shielding property to X-ray corresponds to the thickness of lead of mm, and it was found to have a shielding performance equivalent to 0.2 mm.
（製造時）
板材１０は、既存の樹脂発泡パネルを用い、所望の寸法に切断して板材１０を形成することができる。
また、鋼板２０は、既存の鋼板本体２１に、錫メッキを施し、外側面に錫メッキ層２２を設けることにより形成することができる。この場合、既存の錫メッキ鋼板を用いることも可能である。
(At the time of manufacture)
The board | plate material 10 can cut | disconnect to a desired dimension, and can form the board | plate material 10 using the existing resin foam panel.
The steel plate 20 can be formed by tin plating the existing steel plate main body 21 and providing a tin plating layer 22 on the outer surface. In this case, it is also possible to use an existing tin-plated steel sheet.
そして、板材１０の表面１０ａおよび裏面１０ａに、鋼板２０を接着材（不図示）により貼り付け、放射線遮蔽板Ａを形成することができる。 And the steel plate 20 can be stuck on the surface 10a and back surface 10a of the board | plate material 10 with an adhesive material (not shown), and the radiation shielding board A can be formed.
このように、既存の板材１０と、単に、外側面に錫メッキを施した鋼板２０により製造することができ、汎用性に優れる。 As described above, it can be manufactured by the existing plate material 10 and the steel plate 20 which is simply tin-plated on the outer surface, and has excellent versatility.
（施工時）
本実施の形態１の放射線遮蔽板Ａは、例えば、レントゲン室など、放射線を遮蔽する必要がある部屋の内壁に沿って、設置することができる。また、空間を仕切る間仕切
壁として設置することもできる。
この場合、板材１０として発泡材を用いているため、全体重量が軽く（例えば、５ｋｇ／ｍ２程度）、運搬性および施工性に優れる。
また、放射線遮蔽板Ａの厚さは３ｍｍ程度であるため、内壁に沿って設置した場合の部屋の内寸に与える影響も少ない。
(At the time of construction)
The radiation shielding plate A according to the first embodiment can be installed, for example, along the inner wall of a room such as an X-ray room where the radiation needs to be shielded. Moreover, it can also install as a partition wall which divides space.
In this case, since a foam material is used as the plate 10, the overall weight is light (for example, about 5 kg / m 2 ), and the transportability and the workability are excellent.
Moreover, since the thickness of the radiation shielding plate A is about 3 mm, there is little influence on the inner dimensions of the room when installed along the inner wall.
しかも、鋼板２０は、板材１０に貼り付けているため、鋼板２０として、それ自体では形状保持できない薄さのものを用いても、平面状に形状保持できる。したがって、形状保持可能な厚さの鋼板を用いたものと比較して、全体重量を抑えることができ、これによっても、運搬性および施工性に優れる。
例えば、放射線遮蔽板Ａと同等の放射線遮蔽性能を発揮する厚さ０．２ｍｍの程度の鉛の板材を用いた場合、自重で曲がってしまい、運搬性および施工性に劣る。
And since the steel plate 20 is stuck on the board | plate material 10, even if it is thin as the steel plate 20 which can not be shape-retained by itself, a shape can be hold | maintained in planar shape. Therefore, compared with what used the steel plate of thickness which can maintain shape, whole weight can be held down and it is excellent in conveyance nature and construction nature also by this.
For example, in the case of using a lead plate having a thickness of about 0.2 mm which exhibits a radiation shielding performance equivalent to that of the radiation shielding plate A, it is bent by its own weight and is inferior in transportability and workability.
なお、放射線遮蔽板Ａが１枚では、必要な放射線の遮蔽性能が得られない場合には、この放射線遮蔽板Ａを複数枚厚さ方向に重ねて設置することで、複数倍の遮蔽性能を得ることができる。 If one radiation shielding plate A can not provide the necessary radiation shielding performance, a plurality of radiation shielding plates A may be stacked in the thickness direction to provide a multiple-fold shielding performance. You can get it.
（実施の形態１の効果）
以下に、実施の形態１の放射線遮蔽板Ａの効果を列挙する。
実施の形態１の放射線遮蔽板Ａは、
形状保持可能な板材１０と、
板材１０の表裏面１０ａ，１０ａに積層され、かつ、外側面に錫メッキ層２２が設けられた鋼板２０と、
を備える放射線遮蔽板とした。
したがって、錫メッキ層２２により、放射線を遮蔽することができる。
また、錫メッキ層２２を鋼板本体２１の表面にメッキ層として設けたため、同厚の錫製の板を用いて放射線を遮蔽するものと比較して、錫メッキ層２２の形状を保持でき、これを直接板材１０の表裏面１０ａ，１０ａに設ける場合と比較して施工性に優れる。
しかも、鋼板本体２１も、本実施の形態１のように、0.7〜0.8ｍｍ程度の板厚とした場合、それ単体では形状保持が難しく、運搬性および施工性に劣る。一方、鋼板本体２１を、それ自体で形状保持可能な板厚とした場合、重量が嵩んでしまい、この場合も、運搬性および施工性が悪化する。
それに対し、本実施の形態１では、鋼板２０を板材１０の表裏面１０ａ，１０ａに積層したため、鋼板２０の板厚を薄くしても板材１０により形状保持することができるとともに、重量を低く抑えることができる。
(Effect of Embodiment 1)
The effects of the radiation shielding plate A of the first embodiment will be listed below.
The radiation shielding plate A of the first embodiment is
A plate member 10 capable of holding its shape;
A steel plate 20 laminated on the front and back surfaces 10 a and 10 a of the plate member 10 and provided with a tin plating layer 22 on the outer surface thereof;
Radiation shielding plate.
Thus, the tin plating layer 22 can shield radiation.
Moreover, since the tin plating layer 22 is provided on the surface of the steel plate main body 21 as a plating layer, the shape of the tin plating layer 22 can be maintained as compared with the case of shielding radiation using a tin plate of the same thickness. As compared with the case where the plate 10 is directly provided on the front and back surfaces 10 a and 10 a of the plate 10, the workability is excellent.
In addition, when the steel sheet main body 21 is made to have a thickness of about 0.7 to 0.8 mm as in the first embodiment, it is difficult to maintain the shape of the steel sheet main body 21 alone and the transportability and the workability are inferior. On the other hand, when the steel sheet main body 21 has a thickness capable of holding its shape by itself, the weight is increased, and also in this case, the transportability and the workability are deteriorated.
On the other hand, in the first embodiment, since the steel plates 20 are laminated on the front and back surfaces 10a and 10a of the plate 10, the shape can be maintained by the plate 10 even if the plate thickness of the steel plate 20 is reduced. be able to.
さらに、本実施の形態１の放射線遮蔽板Ａは、板材１０を、発泡樹脂により形成しているため、非発泡樹脂を用いるよりも、放射線遮蔽板Ａの重量を低く抑えることができる。これにより、運搬性および施工性をさらに向上できる。 Furthermore, in the radiation shielding plate A of the first embodiment, since the plate member 10 is formed of a foamed resin, the weight of the radiation shielding plate A can be suppressed to a lower level than using a non-foamed resin. This can further improve the transportability and the workability.
加えて、本実施の形態１の放射線遮蔽板Ａは、金属板として鋼板２０を用いたため、汎用性およびコスト性に優れ、かつ、高い剛性を得ることができる。 In addition, since the radiation shielding plate A of the first embodiment uses the steel plate 20 as the metal plate, it is excellent in versatility and cost performance, and can obtain high rigidity.
しかも、実施の形態１の放射線遮蔽板Ａは、鋼板２０を、板材１０の表裏両面１０ａ，１０ａに設けているため、板材１０の表裏面１０ａ，１０ａの片面のみに設けた場合よりも、２倍程度の高い放射線遮蔽性能を得ることができる。 Moreover, since the radiation shielding plate A of the first embodiment is provided with the steel plates 20 on both the front and back surfaces 10a and 10a of the plate 10, it is 2 more than when provided on only one of the front and back surfaces 10a and 10a of the plate 10 A radiation shielding performance as high as twice as high can be obtained.
さらに、本実施の形態１の放射線遮蔽板Ａは、錫メッキ層２２を、鋼板本体２１の表裏両面２１ａ，２１ｂを含み、外側面の全周面に積層した構成とした。したがって、錫メッキ層２２を鋼板本体２１の表面２１ａ，裏面２１ｂの片面のみに設けた場合と比較して、２倍程度の高い放射線遮蔽性能を得ることができる。
特に、本実施の形態１では、上記錫メッキ層２２を表裏両面２１ａ，２１ｂに有する鋼板２０を、板材１０の表裏両面１０ａ，１０ａに設けることで、厚さ方向に４層の錫メッキ層２２を備えるため、より高い放射線遮蔽性能を得ることができる。
しかも、錫メッキ層２２は、鋼板本体２１をドブ漬けメッキにより形成したため、生産性に優れ、製造コストを低く抑えることができる。また、鋼板２０として既製品を用いることも可能である。
Furthermore, the radiation shielding plate A of the first embodiment has a configuration in which the tin plating layer 22 is laminated on the entire peripheral surface of the outer surface, including the front and back surfaces 21a and 21b of the steel sheet main body 21. Therefore, as compared with the case where the tin plating layer 22 is provided only on one surface of the front surface 21a and the back surface 21b of the steel plate main body 21, high radiation shielding performance about twice as high can be obtained.
In particular, in the first embodiment, the steel plate 20 having the tin plating layer 22 on the front and back surfaces 21a and 21b is provided on the front and back surfaces 10a and 10a of the plate 10, thereby forming four tin plating layers 22 in the thickness direction. Higher radiation shielding performance can be obtained.
In addition, since the tin-plated layer 22 is formed by plating the steel plate body 21 by dip plating, the tin plating layer 22 is excellent in productivity and can suppress the manufacturing cost to a low level. Moreover, it is also possible to use an existing product as the steel plate 20.
また、本実施の形態１の放射線遮蔽板Ａは、錫メッキ層２２の厚さを２５マイクロメートル以下であって、２３マイクロメートル程度としている。
このため、錫メッキ層２２をいわゆるドブ漬により形成可能として良好な生産性を確保しつつ、高い放射線遮蔽性能を得ることができる。
Further, in the radiation shielding plate A of the first embodiment, the thickness of the tin plating layer 22 is 25 micrometers or less, and is about 23 micrometers.
For this reason, it is possible to obtain high radiation shielding performance while securing good productivity by being able to form the tin plating layer 22 by so-called dipping.
以上、本開示の実施の形態を図面に基づき説明してきたが、具体的な構成については、この実施の形態に限られるものではなく、特許請求の範囲の各請求項に係る発明の要旨を逸脱しない限り、設計の変更や追加等は許容される。 As mentioned above, although embodiment of this indication was described based on a drawing, about a specific structure, it is not restricted to this embodiment, It deviates from the summary of the invention which concerns on each claim of a claim. Unless otherwise noted, design changes or additions are permitted.
例えば、実施の形態では、板材として、発泡樹脂により形成された板材を用いた例を示したが、これに限定されず、非発泡性の樹脂（ポリエチレン、ポリプロピレン）や、ベニヤ板などの木製の板などを用いることができる。要は、板材は、放射線の遮蔽性能は不要であり、放射線遮蔽板の形状保持可能な剛性を有していればよく、かつ、錫メッキ層を設けた金属板よりも軽量（低密度）であることが望ましい。 For example, the embodiment shows an example using a plate made of a foamed resin as a plate, but the invention is not limited to this, and it is possible to use a non-foamable resin (polyethylene, polypropylene) or a wood plate such as a veneer board Etc. can be used. The point is that the plate material does not need radiation shielding performance, it needs to be rigid enough to maintain the shape of the radiation shield plate, and it is lighter (less dense) than a metal plate provided with a tin plating layer It is desirable to have.
また、実施の形態では、金属板（鋼板２０）を板材の表裏両面に設けた例を示したが、これに限定されず、表裏面の一方のみ設けた構成としてもよい。
さらに、金属板（鋼板）に設けた金属メッキ層としての錫メッキ層としては、金属板の外側面の全体に亘って設けた例を示したが、これに限定されず、表裏両面あるいはその一方に設けられたものでもよい。例えば、錫メッキ層を外側面の全体に備えた金属板（鋼板）を、所定の大きさに切断したものを用いてもよく、その場合、金属板の外周端面のうちの２面、あるいは、４面を切断面として、これらの端面に錫メッキ層を設けない構成とすることができる。
また、金属板として、鋼板を用いた例を示したが、金属板の材質としては、鋼に限らず錫メッキ層を形成可能なものであれば、銅、亜鉛、ニッケルなどを含む他の金属を用いてもよい。
さらに、実施の形態では、金属メッキ層として錫メッキ層を示したが、これに適用できる金属メッキ層に用いる金属としては、錫に限定されるものではなく、金属板へのメッキが可能であり、かつ、放射線の遮断性を有するものであれば鉛系金属など既知、未知の他の金属を用いることができる。
Moreover, although the example which provided the metal plate (steel plate 20) in the front and back both surfaces of the board | plate material was shown in embodiment, it is not limited to this, It is good also as composition provided only one side of front and back.
Furthermore, although the example provided over the whole outer surface of a metal plate was shown as a tin plating layer as a metal plating layer provided in the metal plate (steel plate), it is not limited to this, Both front and back sides or one side It may be provided in For example, a metal plate (steel plate) provided with a tin plating layer on the entire outer surface may be cut into a predetermined size. In that case, two of the outer peripheral end faces of the metal plate, or It can be set as the structure which does not provide a tin plating layer in these end surfaces by making 4 surfaces into a cut surface.
In addition, although an example using a steel plate as the metal plate has been shown, the material of the metal plate is not limited to steel, but other metals including copper, zinc, nickel, etc., as long as they can form a tin plating layer. May be used.
Furthermore, although a tin plating layer is shown as a metal plating layer in the embodiment, the metal used for the metal plating layer applicable to this is not limited to tin, and plating on a metal plate is possible. And, as long as it has a radiation blocking property, other known or unknown metals such as lead-based metals can be used.
