Lightweight multifunctional radiation shielding will find application in the commercial (e.g., hospitals and nuclear power plants) and defense (e.g., nuclear-powered ships and surveillance satellites) sectors. The shields will provide protection for homeland security first responders employed by law enforcement agencies, fire departments and hospitals. It is also expected that the shielding can be fabricated into temporary shelters used by defense personnel and considered for use in the protection of individuals in case of nuclear or radiological events. The radiation-shielding material will be suitable for fabrication into protective clothing for healthcare professionals involved in X-ray and nuclear medicine. The proposed multilayered multifunctional high performance polymers, films, coatings and additives 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 lightweight structures for planetary rovers and habitats. It is expected that these multi-layered systems will provide a high-performance-to-weight radiation shield that can be used within human habitats, spacecraft and protective apparel. Other missions supported by NASA could also make use of the multifunctional materials for the International Space Station or in other orbiting vehicles involving long-duration small dose exposure.
