Radiation Shields - ILC Dover

Protection of the crew from high energy protons from solar flairs, galactic cosmic radiation, and neutron radiation exposure is one of the major challenges of space exploration. ILC has worked on a number of programs to develop technologies and components to enhance radiation shielding.

Polyethylene is one of the best flexible shielding materials available because of its high hydrogen density, and is the current state of the art. ILC has worked on several materials development efforts in conjunction with NASA LaRC to enhance the protection offered by polyethylene through the inclusion of hydrogen loaded carbon nanotubes, borated polyethylene, and ultra-high molecular weight polyethylene. We are also including anti-microbial and flame retardant capabilities. Some of the work was conducted in partnership with the University of Delaware in the Delaware Center for Space Radiation Studies.

We have designed and manufactured several flexible multi-functional and reconfigurable radiation shield assemblies for space application in an effort to provide the most effective shielding solutions at the lowest mass. These products are made with ILC's ArmorFlex films which are specially formulated for superior properties. Some of our products include:

• Reconfigurable soft sided cargo containers such as the ISS MO2 resupply bag, which can be disassembled and placed where localized shielding is desired
• Stowable water storage jackets that provide water "walls"
• Radiation protective vests that cover a large percentage of the body without severely impacting user comfort or mobility
•  Transportable radiation protective blankets that can be placed where protection is needed
