Patent number: 9093184Abstract: A spacecraft and spacesuit having a radiation shield are disclosed. The shield comprises a hydrogen-containing material encapsulated or bound in a polymer. The hydrogen-containing material has a higher hydrogen content than polyethylene. The hydrogen-containing material may be: encapsulated in a polymer container, sandwiched between layers of polymer, mixed with a polymer as binder, or held in the pores of a polymer foam. The hydrogen may be a hydride or borohydride such as beryllium borohydride, ammonium octahydrotriborate, lithium borohydride tetramethyl ammonium borohydride and beryllium hydride. Methods of manufacturing the shield are also disclosed.Type: GrantFiled: October 17, 2012Date of Patent: July 28, 2015Assignee: Cella Acquisition LimitedInventors: Stephen Bennington, Arthur Lovell, Tom Headen, David Royse, Atahl Nathanson, Stephen Voller, Gang Liu, Stephen Perusich, Sean McGrady
