The Nuclear Paper Trail

Tests, accidents, targets, experiments and a warning meant to last ten thousand years.

15 documents · 1946–2015 · 13 issuers

The nuclear age produced a vast technical literature, much of it declassified into databases that few people browse. These documents run from the first postwar test series to the question of how to warn our distant descendants, and they keep returning to the people downwind.
