Dec 15, 2017 · The official count of 1,054 tests includes 210 atmospheric nuclear tests between 1945 and 1962 - with cameras capturing every one. This week, a team at the federal Lawrence Livermore National Laboratory (LLNL) has released 62 of these atmospheric nuclear test videos on YouTube. An estimated 10,000 of these videos have languished for decades ...
LLNL nuclear weapon physicist Gregg Spriggs is leading a team of film experts, code developers and interns on a mission to hunt down, scan and reanalyze what they estimate to be 10,000 films of the 210 atmospheric tests conducted by the U.S. between 1945 and 1962.

In this film, a device airdropped from about 12,000 feet above the Pacific detonates on October 30, 1962. The film shows the two characteristic light output pulses that are seen only in nuclear weapon blasts, which correlate with the device’s yield (the amount of energy given off from the explosion). The first pulse occurs when the shock wave forms...
Tesla was a relatively low-yield shot of seven kilotons, dropped from a 300-foot tower at the government’s test site in Nevada on March 1, 1955. When the shock wave hits the ground in the video, it kicks up the dry desert soil and “it makes a nice little dust cloud,” Spriggs says. After the second pulse of light reaches its maximum, the bright whit...
The Nutmeg test was detonated from a barge tethered to Bikini Atoll in the Pacific on May 21, 1958. In this film the initial blast and scattering of light are visible but high humidity obscures the fireball itself. As the shock wave travels away from the blast, it changes the atmospheric pressure and creates a low-pressure trough in its wake. Conde...
The Bighorn device was dropped over the Pacific Ocean from a height of around 12,000 feet on June 27, 1962. Thanks to the high altitude, the detonation occurs above the humid layer of the lower atmosphere. The bright light erupts from the second pulse, and then the gases start to escape. As the shock wave propagates downward, it flows through the m...

Dec 14, 2017 · Researchers at Lawrence Livermore National Laboratory (LLNL) released 62 newly declassified videos today of atmospheric nuclear tests films that have never before been seen by the public.
