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. |
