Viewport Glass Passes Radiation Trial

Sample 14-B survived 3000 hours at 1.3× expected dose. The atrium is officially possible.

The atrium was the riskiest promise in the brief. A six-metre curved pane, facing the afternoon sun, needed to hold below 0.2 mSv/day on the guest side. Sample 14-B — a laminate of two leaded silicates with a middle film of boron-doped polymer — just finished its trial at 1.3× the expected chronic dose with no measurable transmission loss. Viewport Shard donors will receive their view-coordinate renders next week.
