| On September 2, 1944, as the explosion ripped through the transfer room of the Naval Research Laboratory's thermal diffusion experimental pilot-plant, the battleship U.S.S. Wisconsin sat berthed not more than 200 yards away. Just back from its "shakedown" cruise, the sailors on board were never made aware that they had been exposed to a cloud of uranium hexafluoride. Although not highly-radioactive, the uranium-hexafluoride is nevertheless, toxic. |
