Patent ID: 7820993

Claim:
Multi-layered radiation protection wall ( 110 ) for shielding against gamma and particle radiation, wherein said radiation protection wall ( 110 ) comprises a sandwich-like structure having at least one first and one second layer arrangement ( 120 , 130 ), wherein said first layer arrangement ( 120 ) comprises at least one primary shielding layer ( 122 , 124 ) and said second layer arrangement comprises at least one secondary shielding layer ( 132 , 134 , 136 ); wherein said primary shielding layer is constructed as a spallation layer and said secondary shielding layer is constructed as a moderation layer, wherein at least one of said first and said second layer arrangements ( 120 , 130 ) is sub-divided into a plurality of wall segments (7-12; 13-16) being at assembling predefined separable, such that said wall segments (10-12; 15-16), which are highly activated by said particle radiation, are constructed separately from said wall segments (7-9; 13-14), which are slightly activated by said particle radiation, and wherein dividing walls are provided between said spallation and moderation layers to enable separated disposal of said spallation and moderation layers.
