Brugger] Radiation levels expected around CMS adjacent areas and more precisely the integrated flux of high-energy hadrons (multi-mev range) pose a significant risk to all electronics not specifically designed or tested for such radiation levels. This document summarizes the respective point iteration as carried out through the R2E study group [1] for the LHC Point 5 and shall serve as basis for all present and future actions. After a general description of the areas and an overview of the equipment and radiation monitoring inventory, reviewed radiation levels are presented and projected to both early as well as later operational conditions. Based on a detailed equipment analysis as performed through the RadWG [2] equipment sensitivities and possible failure rates are deducted, as well as inter-dependencies identified. Possible safety issues, resulting operational constraints as well as the need of radiation test requirements are summarized. Furhtermore, general integration options and constraints are investigated with respect to shielding of areas, as well as possible relocation options. The impact on early (2009/10) and later operation is summarized and respective recommendations are given. For doumentation, the R2E document library [3] has been updated with all P5 related documents. Available simulation results and respective reports were added for all CMS adjacent areas (UJ56, RR53/57, UPS54/56). All provided informations as aquired during the preparation of the review (pictures, documents, comments, layout drawings, rack locations, ) are inclued and available in the above database. It shall be noted, that a careful cross-check of some of the included documents and respective onstraints is constantly required and the reader is encouraged to provide comments to the authors or the R2E study group. 2.
