UK In Danger From Electromagnetic Bomb, Says Defense Secretary

judgecorp writes "Britain must build defenses against an EMP bomb, the UK Secretary of Defense Phillip Hammond told a conference today. Electromagnetic Pulse devices mimic the result of a solar flare or a nuclear explosion in the atmosphere, creating a storm of electromagnetic radiation, which can break mobile networks and satellite systems. Any preparation for solar storms must also consider the possibility of deliberate electromagnetic events, warns Hammond."

Proper surge protection, spark gaps, low pass filters, etc provide a high degree of protection. Narrow band antennas of a grounded design such as a yagi, will recieve power within it's passband.

Unshielded electronics such as your clock radio are hard to protect. Shielded equipment with power filtering, metal cases, over voltage protection, etc are relatively safe. Your desk top computer has an antenna wire attached to the keyboard and mouse, so these are vunerable. A traditional RFI metal case tower PC with all external cables removed would make a nice spare that can be quickly deployed after an attack.

A single point ground at the utility power and telcom entry into a building provides high levels of protection against the lower frequency components of an EMP as MOV, Spark Gap, and other protection is fast enough to ground it. A noise filter for the house power will block the higher frequencies so the over voltage devices can protect the load.

Proper grounding, noise filtering, shielding, and overvoltage protection will provide a high degree of protection to EMP.
