A nuclear electromagnetic pulse is also known as EMP or NEMP is a burst of electromagnetic radiation created by nuclear explosion. There are various different fighting devices that have been designed t o cause this electromagnetic burst. These burst are invisible they occur naturally in nature during a lightning strike and hence cause electrical disruptions nearby. This bursts are likely to cause a lot of perils including nationwide blackout of the electric power grid, and a shutdown of critical infrastructure reliant on the grid.
Nuclear electromagnetic burst are caused by different factors which include detonation of a nuclear bomb, solar flare, a device intended to cause an EMP, close lightning stroke and finally a massive powerline short circuit. Nuclear explosions do not happen at any time unless it is a terrorist attack. Solar flare mostly happen though it is harmless not unless it is in extreme. Computers and computer equipments, appliances containing microprocessors, automobile electronic ignition, power fuses, TV cameras, computer disks among others are some of the electronic devices that are prone to electromagnetic burst. Not all electronic appliances are prone the electromagnetic bursts some are actually very immune they include computers and computer equipments, appliances containing microprocessors, automobile electronic ignition, power fuses, TV cameras, computer disks among others.
Electricity has become part of our daily lives starting with food production and preservation , transport and communication for both domestic and commercial use. There are therefore various ways on how to prepare for an EMP including use of a non electric equipments one can also repair these equipments. To ensure smooth time during the blackout it is good to ensure that equipments made of a semiconductor are avoided as much as possible where one cannot do without them it is good to check the voltage levels to ensure that they are rated to maximum voltage and currents of about ten times.On power wiring it is advisable to use large ferrite beads and also it is good to provide a backup power source like a generator. Use of faraday cage or bag this is any conductive structure that protects its content from electricity pulses. Use of CB radios and walkie talkies to communicate. Make your own electricity power source an example the use of solar panels, biogas, wind turbine generator among others. To avoid food shortage due to the stoppage of production process of food it is advisable to plant food crops.
Care should be taken when designing electrical equipments and when doing wiring the following measures should be put into place shield wiring connected to sensitive equipments or enclose wiring in metal conguits, fuse long wires and cables, increase the current carrying capacity of the building ground
