Ø The resulting electric and magnetic fields may couple with electrical/electronic systems to produce damaging current and voltage surges. Ø The fact that an electromagnetic pulse is produced by a nuclear explosion was known since the earliest days of nuclear weapons testing, but the magnitude of the EM P and the significance of its effects were realized very slowly 1 1/11/11 HIGH ALTITUDE EMP Ø Gamma ray pulse emitted by burst propagates radially outward at speed of light. Ø Gammas scatter off air atoms and generate energetic Compton electrons, primarily between 20 to 40km altitude approximately. Ø Crompton electrons are turned by Earth’s magnetic field.
