Pulse resistant is a notion depicting the ability of a device, community or a machine to survive the wide spectrum electronic pulse emenating from a nuclear blast.
Such a pulse will destroy or severly harm all solid state electronics which, in the last five decades, have come to dominate all communication and computational devices. Only eletronics made of old world vacume tubes not containing any diodes, transistors and solid state electronics can function after suce a pulse.
So a modern car, a cellular phone, a computer will stop functioning after a pulse. Cars that have old style ignition, radioes from before 1935 and camels are not directly influenced.
