“…We have shown long ago that the optimal shielding is to distribute the shield mass as evenly as possible (Wilson et al 1995). 26 First considerations have been to improve the effectiveness of the cooling tubes by a more uniform design with improved protection properties (Ware et al 2003). 27 The replacement of the hard upper-torso (HUT) and backpack with a soft upper-torso and reconfigured Primary Life Support System (PLSS) provides a greater opportunity to improve protection.…”

“…In a previous study (Ware et al 2003), 27 we evaluated the radiation protection characteristics of some proposed new spacesuit materials. Fifteen test target combinations of current and experimental spacesuit materials were exposed to a low energy proton beam at Lawrence Berkeley National Laboratory (LBNL).…”

Meeting radiation protection requirements during EVA is predominantly an operational issue with some potential considerations for temporary shelter. The issue of spacesuit shielding is mainly guided by the potential of accidental exposure when operational and temporary shelter considerations fail to maintain exposures within operational limits. In this case, very high exposure levels are possible which could result in observable health effects and even be life threatening. Under these assumptions, potential spacesuit radiation exposures have been studied using known historical solar particle events to gain insight on the usefulness of modification of spacesuit design in which the control of skin exposure is a critical design issue and reduction of blood forming organ exposure is desirable. Transition to a new spacesuit design including soft upper-torso and reconfigured life support hardware gives an opportunity to optimize the next generation spacesuit for reduced potential health effects during an accidental exposure.
