North Korea's recent nuclear weapons test fuels concerns over a potential high altitude Electromagnetic Pulse Attack

North Korea's recent nuclear weapons test is fueling concerns over a potential high altitude Electromagnetic Pulse Attack, which could cripple power supplies across a wide area. An Electromagnetic Pulse takes effect when a nuclear warhead explodes above the Earth's atmosphere releasing a burst of Gamma Rays, which consist of high energy electromagnetic radiation. Waves of radiation collide with Oxygen and Nitrogen atoms stripping away electrons. When these Electrons interact with the Earth's magnetic field, it creates a brief but intense burst of downward-moving radiation. An Electromagnetic Pulse does not kill or injure humans, but produces an energy surge that can overload and wreck unprotected electrical systems, crippling power supplies across a wide area.  [courtesy: AFP]
