    • PROBLEM TO BE SOLVED: To provide means of easily and effectively shielding radiation at low costs.SOLUTION: Provided are a radiation shield formed from wood or a wood-derived material, a radiation shielding structure which includes the same as a constituent, and a method of shielding radiation which uses wood or a wood-derived material as a radiation shielding material. For example, when conveying or transporting a relatively large quantity of radioactive waste or the like whose radiation level exceeds a reference level, a certain amount of radiation can be shielded relatively easily at low cost by surrounding an area loaded with the radioactive waste with wood or wood-derived material. For another example, when disposing or storing a relatively large quantity of radioactive waste or the like whose radiation level exceeds a reference level, storage facilities can be built relatively easily at low cost by installing radiation shields formed from wood or wood-derived material around a disposal or storage area.
    • 要解决的问题:提供以低成本容易且有效地屏蔽辐射的方法。解决方案:提供由木材或木材衍生材料形成的辐射屏蔽,包括与其成分相同的辐射屏蔽结构,以及方法 的屏蔽辐射,其使用木材或木材衍生材料作为辐射屏蔽材料。 例如,当输送或运送辐射水平超过参考水平的相对大量的放射性废物等时,通过围绕装载有放射性废物的区域以木材或其他方式围绕放置废物的区域可以相对容易地屏蔽一定量的辐射, 木材来源的材料。 另一个例子,当放置或存放其辐射水平超过参考水平的相对大量的放射性废物等时,通过将围绕着木材或木材的材料形成的辐射屏蔽安装在低成本下可以相对容易地建造存储设施 处置或储存区域。

    • PROBLEM TO BE SOLVED: To provide an organism adhesion type panel member and an organism adhesion method on a surface of a structure for facilitating its construction. SOLUTION: This organism adhesion type panel member 1 has a panel board 5 forming the surface of the structure 2, an organism adhesion block 10 with clearance constituted by molding and hardening a stringy body 12 of mortar or concrete 11 containing mixed short fibers and being extruded by the predetermined thickness on a rear surface 7 of the panel board 5 in a layer having clearance, and a plurality of organism gateway holes 9 passing through the panel board 5 from its surface 6 to its rear surface 7 and communicating with the clearances in the block 10. Preferably, a plurality of blocks 10 having the stringy bodies 12 being different in thickness, a plurality of blocks 10 being different in ratio of clearances, and/or a plurality of blocks 10 being different in shape of clearance are fixed on the rear surface 7 of the panel board 5.

    • PROBLEM TO BE SOLVED: To provide a creature adhesion preventing method for preventing creaturies from adhering to the surface of a member that makes contact with sea water or plain water, without depending on artificial functions such chemicals. SOLUTION: In the creature adhesion preventing method for preventing sea water (or plain water) creaturies from adhering to the surface of the member making contact with sea water (plain water), an immersible mortar or concrete material having plant fibers mixed therein is used as a material forming the member, and plain water (sea water) is flowed from inside the material to the surface of the material, facing the sea water (plain water). The immersible mortar or concrete material having the plant fibers mixed therein has pores such that water naturally soaks/flows into a hardened body matrix by virtue of mixture of the plant fibers.
