The second radiation shielding materials 3 are arranged in parallel with a distance corresponding to the thickness of the second radiation shielding material 3 between each other, and the plurality of second radiation shielding materials 3 are also arranged between the first radiation shielding materials 3 with each other. The radiation shielding material 2 is arranged at a distance corresponding to the thickness of the radiation shielding material 2.

  In addition, the first radiation shielding material 2 and the second radiation shielding material 3 are cut out from, for example, a single radiation shielding material so that the width is in a range of 2 mm to 3 mm and is long. Can be used.

  As shown in FIG. 3, the first radiation shielding material 2 has a first surface and a second surface, and is a lead thin film formed into a thin film shape so as to be flexible with a lead material. A layer 4, a first covering layer 5 which is laminated on the first surface of the lead thin film layer 4 and is made of a plastic material and has flexibility, and is laminated on the second surface of the lead thin film layer 4. And a second covering layer 6 made of a plastic material and having flexibility.

  Similarly to the first radiation shielding material 2, the second radiation shielding material 3 has a first surface and a second surface, and lead formed in a thin film shape so as to be flexible by a lead material. On the second surface of the thin film layer 4, the first covering layer 5 laminated on the first surface of the lead thin film layer 4 and made of a plastic material and having flexibility, and on the second surface of the lead thin film layer 4 And a second covering layer 6 made of a plastic material and having flexibility.

  Since the lead thin film layer 4 used for the first radiation shielding material 2 and the second radiation shielding material 3 shields radiation, the thickness is 0.03 mm to ensure a sufficient shielding effect. It is preferable to be within a range of 0.2 mm.

  In this embodiment, the lead thin film layer 4 is manufactured by a rolling process and has a thickness of 0.05 mm. However, in the present invention, the manufacturing method of the lead thin film layer 4 is not limited to the rolling process, and is manufactured by another manufacturing method.
