Prior to WW II the
Kodak Company had gone to considerable trouble to ensure that the

Recognizing the sensitivity of this
information, Dr. Webb kept his discovery secret until 1949.
In response to this event, the Kodak Company installed air samplers in the intakes of their building ventilation system to monitor for fallout.
