This paper is based on a study conducted by Sasakawa International Center for Space Architecture (SICSA) between September 2008 and February 2009. SICSA has been awarded key roles in helping two aerospace company teams plan living and working accommodations for early lunar surface missions. SICSA has major conceptual design responsibilities on teams headed by Boeing and ILC-Dover which were separately selected out of more than 20 competing proposals for two out of three total NASA study contracts. Major study priorities were to determine minimum habitat requirements essential to keep crews alive and safe from harm during the first month-long missions, and then expand these accommodations as operations, facilities and amenities are extended. This paper discusses important points of radiation protection design options and known radiation protection materials applications with a special emphasis upon comparative mass implications for several proposed habitat configuration concepts. These comparisons are correlated with shielding surface area rather than actual mass estimates due to current data uncertainties regarding a number of issues: unresolved questions concerning how much radiation protection will be mandated, what mitigation strategies will be selected, what types and thicknesses of materials will be used, and how much of the total allowable module mass can be allocated for this purpose.
