Title: Multilayer Polymeric Shielding to Protect Humans from Galactic Cosmic Radiation
Agency: NASA
Contract: NNX10CF05P
Award Amount: $100,000.00


In Sub-topic X4.01, NASA has identified a need for advanced radiation-shielding materials and structures to protect humans from the hazards of galactic cosmic radiation (GCR) on long-duration lunar 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 development of lightweight, multi-layered, polymeric shielding against GCR. Phase I Technical Objectives include selection, design and fabrication of materials tailored to shield against hazardous radiation, and measurement and test of individual and layered materials using available radiation sources. The anticipated result of the Phase I and Phase II programs is the development of multi-layered shields with an outer layer of hydrogenous polymeric material for significant dose reduction of incident GCR ions and inner layers of polymeric composites containing additives chosen to moderate and absorb neutrons resulting from fragmentation of incoming heavy ions and to absorb short wavelength electromagnetic radiation resulting from the slowing of the GCR particles and capture of neutrons. The Technology Readiness Level (TRL) at the beginning of Phase I is 3. At the end of Phase I, the TRL will be 4 or higher.
