TECHNICAL ABSTRACT (Limit 2000 characters, approximately 200 words)
NASA has identified a need in Sub-topic H11.01 for advanced radiation-shielding technologies using in situ resources, such as regolith, to protect humans from the hazards of galactic cosmic radiation (GCR) during extra-terrestrial missions. The radiation species of greatest interest are light ions (particularly protons), heavy ions (such as iron-56) and neutrons. International Scientific Technologies, Inc., in conjunction with The College of William and Mary, proposes the use of regolith combined with hydrogenous polymers to develop radiation-shielding structural materials for habitats. The program Technical Objectives include selection of hydrogenous polymer binders for use in regolith radiation-shielding materials, fabrication of polymer-regolith specimens designed to shield against galactic cosmic radiation species and to act as structural components in habitats, and acquisition of test data to determine key parameters for the development of optimal radiation-shielding regolith-composite materials. The innovation is the development of polymer-regolith composites for structural radiation-shielding materials to protect humans on deep-space missions. The anticipated result is the creation of composite materials that combines in situ resource utilization (ISRU), i.e. regolith, with a hydrogenous polymeric matrix. Additives, such as boron, could be included to enhance absorption of neutrons generated by interactions of GCR and SPE particles with shielding materials. The proposed composites have multifunctional properties of radiation shielding against galactic cosmic radiation, neutrons and electromagnetic radiation, and structural integrity to permit use in habitats.

POTENTIAL NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
The proposed multifunctional high-performance polymers will find application in NASA missions in protecting astronauts and sensitive optical, electronic, thermal and acoustic components from space hazards, including radiation, dust and thermal transients, while, at the same time, providing structural components for habitats. It is expected that these polymer-regolith composite systems will provide a high-performance-to-weight radiation shield that can be used for human habitats.

POTENTIAL NON-NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
Multifunctional radiation shielding will find application in the commercial sector in reducing collateral damage from heavy charged particles emerging as a therapeutic approach in nuclear medicine. The Departments of Defense and of Homeland Security will find applications that include protection of soldiers, first responders and emergency medical personnel against high energy gamma radiation and neutrons resulting from so-called dirty bombs as well as from hazards brought about through accidental release of radiological materials.
