| [WHKROG] This sequence of three shots were taken by a ' telephoto' version of the Rapatronix, with a 160-inch (4064mm) focal length Cassegrain lens, looking directly into the shot tower at the device at 'zero time'. The rectangular object seem is the actual weapon casing. The 'light' seen around the weapon casing is called "Teller light' after the physicist Dr. Edward Teller. When a nuclear device explodes, the first products of the reaction are X-rays, which penetrate the bomb casing without destroying it. When outside the bomb casing, the X-rays encounter normal temperature air, which is opaqueto X-rays. So the X-rays are abssorbed by and excite the air molecules to a higher energy state for a very brief period, after which they 'fall back' into a lower energy state and emit that excess energy largely as photons of light. |
