<p><P>PROBLEM TO BE SOLVED: To provide a radiation shield structure capable of enhancing a radiation shield effect and efficiently charging a shield into a cylindrical body, and to provide a construction method for a radiation shield structure. <P>SOLUTION: In a construction method of a radiation shield structure 10, a first partition body 28 is installed by being pressed into an outlet end 12B side from an inlet end 12A of a sleeve 12, while avoiding six existing pipes 14, 14... in a sleeve 12. Then, a lead wool shield 22 is stuffed on a front side of the first partition body 28 and a second partition body 30 is installed by being pressed into a front side of the lead wool shield 22. Then, solid shield materials 24, 24... are stuffed into a front side of the second partition body 30. After closing the inlet end 12A of the sleeve 12 by a cover 88, a liquid shielding agent 26 is injected into a gap between the cover 88 and the second partition body 30 and cured. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
