High Altitude Nuclear Detonations (HAND) Against Low Earth ... Starfish Prime: The Largest Nuclear Test in Space

Looking for abbreviations of HANE? It is High-Altitude Nuclear Explosion. High-Altitude Nuclear Explosion listed as HANE. High-Altitude Nuclear Explosion - How is High-Altitude Nuclear Explosion abbreviated? High-Altitude Nuclear Explosion: HANE: High Altitude Nuclear Effects: HANE: History of the Ancient Near East: HANE: Housing Action

The Soviet high-altitude nuclear burst of 0912 UT on November 1, 1962, produced delayed perturbations of the VLF transmissions monitored at APL/JHU over five paths remote from the burst region. The burst-related VLF effects varied from 6 to 55% and averaged 32% of the normal diurnal variation. It is suggested that the VLF phase perturbations are produced by particles from the burst that drift High Altitude Electromagnetic Pulse (HEMP) and High Power ... High-Altitude Electromagnetic Pulse (HEMP) is an electromagnetic energy field produced in the atmosphere by the power and radiation of a nuclear explosion, and that is damaging to electronic equipment over a very wide area, depending on the design of the nuclear device and altitude of the burst. Effect of the starfish high altitude nuclear explosion on ... The effect of a high altitude nuclear explosion such as the Starfish burst of 9 July, 1962 on the electron loss rate in the F2-region is discussed.A method for computing the electron density profile at various times after detonation is developed and the results are compared with available observations. High Altitude Electromagnetic Pulse (HEMP) and High Power ... High Altitude Electromagnetic Pulse (HEMP) and High Power Microwave (HPM) Devices: Threat Assessments Background A Commission to Assess the Threat from High Altitude Electromagnetic Pulse (EMP commission) was established by Congress in FY2001 after several experts expressed concern that the U.S. critical infrastructure and military were vulnerable

Nuclear Weapon EMP Effects. A high-altitude nuclear detonation produces an immediate flux of gamma rays from the nuclear reactions within the device.

Nuclear weapon - Residual radiation and fallout | Britannica Nuclear weapon - Nuclear weapon - Residual radiation and fallout: Residual radiation is defined as radiation emitted more than one minute after the detonation. If the fission explosion is an airburst, the residual radiation will come mainly from the weapon debris. If the explosion is on or near the surface, the soil, water, and other materials in the vicinity will be sucked upward by the Ionospheric effects of high-altitude nuclear explosions ... Ionospheric effects of high-altitude nuclear explosions 923 ionospheric conditions of the layer, i.e. on its initial ionization density and the height of reflection. It may be further noted here that in case of a solar-flare there is, initially, a decrease followed by a sharp increase in the long-wave signal. Determination of the D-Layer Air Chemistry from a Daytime ... A discussion of the properties of X-ray-induced absorption in a daytime environment. Measurements of the magnitude and time dependence of X-ray-induced absorption over Midway during the nighttime high-altitude nuclear explosion of July 9, 1962 allowed one to infer bounds on the dissociative recombination coefficient alpha of the D-layer of the ionosphere. The Effects of Nuclear Weapons, 1977: Descriptions of ...

Effects of high-altitude nuclear explosions on radio noise received noise power amounted to as much as 32 db in the hour following the first explosion. The period of time over which abnormal noise condi tions were observed suggests that high­ altitude nuclear explosions may have a rather persistent effect on radio communications at certain frequencies. 1. … Geophysical Effects of High-Altitude Nuclear Explosions ...

But there's a lesser-known consequence of a nuclear explosion that can drastically expand its damage zone: an electromagnetic pulse, or EMP. EMPs are rapid, invisible bursts of electromagnetic energy.
