A few interesting “new” (to me) additions to the AP Archive on YouTube.

U.S. Army nuclear weapons countermeasures at Operation Desert Rock, Nevada test site. Desert Rock nuclear tests, Nevada test site. Includes films of the first ever nuclear surface burst, the 1.2 kt “Jangle-Sugar” test, Nevada, 1951 (all previous nuclear explosions had been air, tower, or underwater bursts), and the first shallow underground test, the 1.2 kt “Jangle-Uncle” test, Nevada, 1951. Film shows the heat, blast and radiation protection afforded by military equipment, foxholes, and the (apparent) simplicity of fallout decontamination.
“…troops observed the detonation at a distance of 5 miles and did not closely approach ground zero. Near ground zero the radiation level was 5000 roentgens/hour at one hour after the test, with levels of 1000 R/hr extending up to 1200 yards from the burst point. Hazardous levels of 100 R/hr extended past 5000 yards in some areas.”
