Description
【発明の詳細な説明】 「産業上の利用分野] 本発明は放射線防護服に関する。[Detailed description of the invention] “Industrial application field” The present invention relates to radiation protection clothing.
[従来の技術] 従来の放射線防護服としてはつぎのらのがある。[Conventional technology] Conventional radiation protection clothing includes the following:
■鉛系粉末をゴム、プラスチックなどに充項したシート
を用いたもの
■鉛毛を布で挾み込んだシートを用いたちの■ポリエチ
レンシートなどに鉛系金属ホイルが一体に積層されたシ
ートを用いたもの
■ポリエチレンシートなどと鉛系金属ホイルとを交互に
積重ねたシートを用いたもの
[発明が解決しようとする問題点1
ところで従来の防護服にはっぎのような問題がある。■ Sheets made of rubber, plastic, etc. filled with lead-based powder ■ Sheets made of sheets with lead wool sandwiched between cloth ■ Sheets made by laminating lead-based metal foil on polyethylene sheets, etc. Items used ■ Items using sheets made by alternately stacking polyethylene sheets or the like and lead-based metal foil [Problem to be solved by the invention 1 By the way, conventional protective clothing has a similar problem.
前記■のシートは鉛の粉末の隙間から放射線が透過しや
すいので、有効な遮蔽効果をうるためには非常に分厚い
ものが必要となる。Since radiation easily passes through the sheet (2) through the gaps between the lead powder, it needs to be very thick in order to obtain an effective shielding effect.
前記■のマットは繰返して市げられると鉛毛に破断が起
こるので耐久性に劣ると共に密度が低く、そのため有効
な遮蔽効果をうるためにはこれも非常に分厚いものが必
要となる。If the mat described in (2) is used repeatedly, the lead fibers will break, so it is inferior in durability and has a low density. Therefore, it also needs to be very thick in order to obtain an effective shielding effect.
前記■および■のシートでは数枚積層して用いるとき、
ポリエチレンシートの厚さも数倍の厚さに増えるので、
全体に非常に分厚いものとなる。When using the sheets of ■ and ■ above by laminating several sheets,
The thickness of the polyethylene sheet increases several times, so
The whole thing is very thick.
以上のように従来の防護服では、全体に分厚つく嵩張っ
ており、作業者の行動を束縛することが多いという欠陥
がある。As described above, conventional protective clothing has the disadvantage that it is thick and bulky, and often restricts the actions of the worker.
しかるに従来の防護服用材料が、いずれも鉛を加工した

ゆえに従来の放射線防護用材料の開発方向としては、い
かにして耐屈曲性および機械的強度の向上をはかるか、
あるいは軽量化をはかるかという面にのみ注意が向けら
れていた。However, the reason that all conventional protective clothing materials use processed lead is that, for example, lead sheets alone have poor mechanical strength (for example, tear resistance) and bending resistance, which is a problem when worn as clothing. It was based on the recognition that it was inferior and could not be used until that point.Therefore, the direction of development of conventional radiation protection materials was to improve the bending resistance and mechanical strength. ,
Alternatively, attention was focused only on how to reduce weight.
本発明者らも当初は叙上の技術的常識に沿うて放射線防

本発明は叙上のごときまったく意外な発見に基づいてな
されたものであり、動きやすく充分な放射線遮蔽能力を
有する放射線防護服を提供しようとするものである。The inventors of the present invention initially considered the development of radiation protection 1ffil in accordance with the technical common sense mentioned above, but surprisingly, even the form of a lead sheet alone was sufficient when sewn with the exterior fabric of clothing. I! A new discovery has been made that the clothing has mechanical strength and bending resistance.The present invention was made based on the above-mentioned completely unexpected discovery, and provides radiation protection clothing that is easy to move in and has sufficient radiation shielding ability. This is what we are trying to provide.
[問題点を解決するための手段]
本発明は厚さ20〜300μmの鉛シートを積重ねてな

る材料で縫製された放射線防護服を要旨とする。[Means for Solving the Problems] The gist of the present invention is a radiation protective suit made of a material in which a radiation shielding material made of stacked lead sheets with a thickness of 20 to 300 μm is sewn together with a radiation-resistant fabric. do.
[作用および実施例1
本発明に用いる鉛シートとしては、純鉛または合金鉛が

のものが用いられる。[Operation and Example 1] Pure lead or alloy lead can be used as the lead sheet used in the present invention. JIS H2105 (195
Examples include Class 5 lead ingots specified in 5) and Class 4 to Special Lead ingots with higher purity than the lead ingots. Preferably, one having a purity of 99.8% by weight or more, particularly a purity of 99.9% by weight or more is used.
合金鉛としては、たとえば5n−Sb系合金(Sr15
%、Sb 1.5%)、Sn合金(Sn 10%)など
が用いられる。As the lead alloy, for example, 5n-Sb alloy (Sr15
%, Sb 1.5%), Sn alloy (Sn 10%), etc.
鉛シートの厚さは20〜300μm、好ましくは50〜
200μ11 とくに好ましくは75〜150IINが
採用される。 20μ層よりも薄いものは91造が困難
となるだけでなく、所望の機械的強度をうろことができ
なくなる。また300μ2よりも厚いものは可撓性や耐
屈曲性がわるくなる。The thickness of the lead sheet is 20-300μm, preferably 50-300μm
200μ11 Particularly preferably 75 to 150IIN is employed. If the layer is thinner than 20 μm, not only will it be difficult to construct the 91-layer structure, but it will also be impossible to achieve the desired mechanical strength. Moreover, if the thickness is more than 300μ2, the flexibility and bending resistance will be poor.
本発明の放射線遮蔽材は鉛シートの合計の厚さが約0.
2mm以上となるように積重ねるとき多くのばあい充分
な遮蔽効果かえられ、たとえば鉛シートを2〜20枚、
好ましくは2〜15枚、とくに好ましくは2〜10枚積
重ねればよい。In the radiation shielding material of the present invention, the total thickness of the lead sheets is about 0.
In many cases, a sufficient shielding effect can be obtained when stacking them to a thickness of 2 mm or more; for example, 2 to 20 lead sheets,
Preferably 2 to 15 sheets, particularly 2 to 10 sheets may be stacked.
本発明で用いる鉛シートは薄いので、意外にも#i返し
曲げ疲労や可撓性に優れでおり、それらが積重ねられた
本発明の放射#a遮蔽材も鉛シートの前記特性をすべで
継承している。Since the lead sheet used in the present invention is thin, it surprisingly has excellent #i bending fatigue and flexibility, and the radiation #a shielding material of the present invention in which these sheets are stacked also inherits all of the above characteristics of the lead sheet. are doing.
従来、鉛シートの単独使用で懸念されてぃた破断しやす
さは、外装の布地と縫い合わせ、その縫合部によって鉛
シートにかかる力を分散させることにより解消される。Conventionally, the fear of breakage when using lead sheets alone can be resolved by sewing them together with the exterior fabric and dispersing the force applied to the lead sheets through the seams.

ものである。Therefore, when the radiation shielding material according to the present invention is used in protective clothing, there is no or almost no need for base sheets other than lead sheets, and as a result, the thickness of the protective clothing is not bulky and the weight is light. The ideal protective clothing is one that does not restrict freedom of movement too much and can be easily carried around.
