Radiation Shielding Sheath

The Prothean device is being built in space, where its inner workings may be vulnerable to cosmic radiation from nearby stars. While the construction plan has taken standard risks into account, a sudden turn in space-weather could pierce the basic shielding and irradiate the device and crew. Superior radiation shielding used by the orbital stations near the gas giant Sineus would provide a low-cost way to keep the device safe against all but the most unusual energetic emissions.
