hi all !
here is a tech question would 6 inch of reenforced concret stop most emp from frying my radios and cbs sets ?
emp = electromagnetic pulse aka sun flare or nuke bomb :)
Can any 1 here tell me for sure ? or do i need a metal bax to ?
emp = electromagnetic pulse.
and no, I do not believe concrete will help.
EMP Expert to Assist
If you decide to build a box please make sure that you nest the equipment for added protection. Do not use a ground wire as most people suggest because it is not necessary and could work against you. Not grounding the box will cause the energy to be diverted around your box into the air instead of into the ground which during an EMP event will be electrically charged.
If you need help let me know
Use vacuum tubes instead.
And IIRC 10 megatons will cause brush fires within a 35 mile radius.
Put enough rebar in it and ground the hell out of it....and it might reduce the induced current.....
The amount of current in an EM pulse is a function of the source, the distance from it, the length of the wire and the orientation of the target.
A wire perpendicular to the pulse will have little current induced.....whereas, a wire parallel to the pulse will get the maximum current induced....typically the current is expressed as amps/meter.
You will know if WWIII is starting if a 40 megaton blast happens in low earth orbit above the central US.
