STRUCTURE FOR ATTACHING RADIATION SHIELD WINDOW |
摘要 |
PROBLEM TO BE SOLVED: To provide a structure for attaching a radiation shield window capable of sufficiently intercepting both electromagnetic waves and a neutron beam without lowering the function as radiation shield window. SOLUTION: In the attaching structure of radiation shield window for attenuating radiation R (R1 to R3) passing through the gap between a radiation shield wall 2 and a radiation shield window 3 penetrating the radiation shield wall 2, radiation shield reinforcing members 1 are interposed in the gaps. The radiation shield reinforcing members 1 is formed by forming more than two layers of electromagnetic shield layers A and more than two layers of neutron shield layers B alternately in the thickness direction (z) of the radiation shield wall 2.
