PROBLEM TO BE SOLVED: To solve the problem that a nuclear accident disaster area is not provided with a material having a radiation shield performance and a radiation transmission containment performance for the purpose of preventing the damage arising from radiation transmitting footwear such as shoes in radiation exposure elements, and consequently, the situation still continues in which the radiation exposure is unable to be prevented and there is provided no composite material manufacturing technology for mixing a radiation shield performance and a radiation transmission containment performance surface material (fiber-based, sheet-like) of the present device into an insole inside footwear, the surface and backside of a footwear bottom body or a hollow or a footwear component material and for exhibiting an exposure containment function, and there is provided no manufacturing technology of the material which is inserted into a finishing material such as a wall paper and others used by exposure containment clothing and interior/exterior architectural materials, and there is provided no manufacturing technology of a temporary storage container material such as a radiation contaminated material and others and a transfer container material.SOLUTION: A spread of exposure health disasters is prevented: by neutralizing a mixture of lime-based material and borax or the mixture of lime-based material and borax added with boric acid and sodium silicate-based material; by using surface materials and others in which a radiation shield performance and a radiation transmission containment performance of the present device are made to act on cloth-based, fiber-based, metal-based, wood-based, and synthetic resin-based material; and by providing manufacturing technology of footwear, architectural materials, transfer containers, temporary storage containers, and clothing which prevent exposure health disasters.

PROBLEM TO BE SOLVED: To create a radiation shield material that is highly sufficient in the ability to shield radiation, is high is self-standing and strength without using plaster board, iron plate, concrete, or the like together, and, furthermore, is able to recycle glass categorized and recovered for recycling.SOLUTION: An organic inorganic composite according to the invention does not contain lead substantially and does contain 30 to 90% by mass of glass recovered for recycling and 10 to 70% by mass of organic material. The composite is used for a radiation shield material. The glass recovered by recycling is, for example, panel glass of cathode-ray tube, glass of plasma display, optical glass, or the like.

PROBLEM TO BE SOLVED: To provide a radiation shield glass laminate 10 which can reliably prevent dielectric breakdown without reducing radiation shield capability of glass, and a construction method thereof.SOLUTION: A glass laminate is formed by laminating plural sheets of radiation shield glass 11 bonded to each other with an adhesion layer 12. On one face of at least one sheet of radiation shield glass, a transparent conductive layer 13 is formed. The radiation shield glass laminate is prepared, an outermost layer on a side adjacent to the transparent conductive layer is disposed on a side closer to a radiation source in a lamination direction of the radiation shield glass.

PROBLEM TO BE SOLVED: To provide a technology for easily reducing and shielding radioactivity emitted from a radioactive contaminant surface at low cost.SOLUTION: Crushed Ryukyu limestone fine particles are sprayed to a radioactive contaminant surface to reduce and shield the amount of emission radiation. The average particle diameter of a crushed Ryukyu limestone is 50-5,000 μm, and a spray method may be a method using an agricultural scattering machine or an aerial scattering method using an aircraft. The Ryukyu limestone 1.0 to 10 kg of the average particle diameter of 50-5,000 μm is desirably scattered per radioactive contaminant surface 100 m. As a radioactive contaminant of a treatment object, radioactive contaminants of agricultural soil, road surface soil, forest, playground surface soil, building structures, and the like are listed.
