Patent ID: 7728315

Claim:
A doorless radiation attenuation corridor through which patients pass through to a room containing a source of radiation, said corridor comprising: an entry corridor having walls, a ceiling and a floor made of radiation resistant materials, said entry corridor defining a first axis along which said patients pass from a safe region; an intermediate corridor attached to said entry corridor, said intermediate corridor having walls, a ceiling and a floor made of radiation resistant materials, said intermediate corridor defining a second axis along which said patients pass, said second axis being at substantially a 90° angle to said first axis; said walls of said intermediate corridor having portions which are substantially parallel to one another, said substantially parallel portions of said walls of said intermediate portions forming angles with said second axis of between 10° and 45°; a final corridor leading to said room containing said radiation source, said final corridor having walls, a ceiling and a floor made of radiation resistant materials, said final corridor defining a third axis along which patients pass said third axis being at substantially a 90° angle to said second axis; wherein radiation from said radiation source is substantially attenuated between said radiation source and said safe region in a doorless corridor.
