■ 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.

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.

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.

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.
