Our space radiation shielding for the protection of electronics and optics is an advanced material called PolyRAD.

PolyRAD was developed under a SBIR contract from NASA Marshall Space Flight Center, both Phase I and Phase II.

The dose-reduction performance of PolyRAD is equivalent to that of tungsten at a mass savings approximately from 20 to 30 percent, depending on the orbit.  Our machining  techniques enable us to more efficiently fabricate net-shape shields from castings than would be the case using tungsten or other shielding materials.  Depending on the orbit, from 3 to 6 orders of magnitude of total dose reduction can be achieved.
