For citizens, FEMA has some simple advice on a nuclear strike: Get inside, stay inside, and stay tuned. Does FEMA not know about EMP?

    Are they still pretending a nuclear would be survivable to justify having huge numbers of nuclear weapons?

      Yes, and Superman will save us too.

    re you comment on transistor junctions - there are two effects - the radiation pulse that will turn on transistors for a short time. If they are in a totem pole configuration AND the equipment is on, then that could damage the transistors. The second effect is the EMP which induces currents in circuits and can damage electrical devices.

    If your equipment is affected by the radiation pulse then you are probably already dead anyway.

    The EMP can be mitigated by wrapping your radio in foil or keeping in a tin at the time of the detonation.

    Apparently they don't know about radiation, firestorms, acoustic vibrations, or radioactive fallout either.

    EMP effects are proportional to both the size and proximity of the device or wiring.

    Things like power grids and land line phone cables that act like large antennas could have high voltages induced at quite long ranges - but self-contained things like battery powered portable radios would likely not be affected much beyond the lethal range of a bomb anyway.

      Well, I've only been designing radio and electronics gear for around 40 years...
      The facts ar as I stated them.
