US Patent 7820993 Multi-layered radiation protection wall and radiation protection chamber

The invention relates to a multi-layered radiation protection wall for shielding against gamma and/or particle radiation of a reaction site of an accelerator facility, wherein the radiation protection wall comprises a sandwich-like structure with at least a first and a second layer arrangement, wherein the first layer arrangement has at least a primary shielding layer and the second layer arrangement has at least a secondary shielding layer. Thereby, at least one of the first and the second layer arrangements is sub-divided into a plurality of wall segments, whereby a selective disposal is made possible. Thus an increased cost efficiency is achieved and the environmental impact is lowered.
