U.S. Department of Defense: Exercise Desert Rock
(1951).
'In 1951, the Army, working with the Atomic Energy Commission,
carried out the Desert Rock Exercises, an experiment to "dispel
much of the fear and uncertainty surrounding atomic radiation and
the effects of gamma and x-rays." The following is a recorded
interview between a sergeant and a training officer prior to a
blast:
Question. "How many of your men would volunteer to go up and be in
the foxholes?" (one-half mile from ground zero).
Answer. "I guess about half a dozen."
Question. "It's quite a loud noise when that bomb goes off ...
would it do them any harm?"
Answer. "No sir, not the noise, no."
Question. "How about the radiation? Do you think there is much
danger?"
Answer. "Radiation is the least of their worries that the men are
thinking about."
Question. "I think most thought radiation was the greatest danger,
didn't they? Where did they learn differently?"
Answer. "They were, prior to our instructions here. We received a
very thorough briefing."'

'Operation RANGER was the first continental nuclear test series
conducted at the Nevada Proving Ground (now called the Nevada Test
Site). With the exception of the Trinity shot in New Mexico, all
previous weapons testing was conducted at the Pacific Proving
Ground in the Marshall Islands area. From January through February,
1951, five airdrop tests were conducted. Some of the shots were
designed to test trigger devices for weapons to be tested in
Operation GREENHOUSE scheduled for the Spring: This secret film has
been sanitized, with secret portions removed, after the complete
version was locked away for decades in top secret vaults, where the
unsanitized version remains to this day. The celluloid version of
these films are increasingly brittle and very few people have
security clearances to view the unedited versions that contain
jealously guarded secrets to this day'.
