AVR-Chat

I missed the part about radios, radar, etc. So, in addition to  
transient protectors, liberal use of lossy ferrites (beads, etc) are  
strongly called for.

There really is no one technology that will handle the full spectrum  
of ESD, lighting, general conducted EMI, and RF through microwave. I  
am sure that I'm not the only one on the list who has been through  
this commercially. Its NOT a trivial task and its particularly  
difficult to do with confidence in the absence of testing. Lacking  
that, you are going to have to rely on your own interpretation of  
other's experiences and hope that you understand what is offered.
