Unless you have a security clearance and need to know, >nobody can tell you anything very specific. Yes, this is stupid. A good unclassified source of info is "Compliance Engineering" a publication by Dash, Straus + Goodhue, 629 Mass Ave., Boxborough MA. They are an FCC/Tempest advice house, and publish an annual "how-to" guide. The guide is wonderful reading, giving many amazing numbers. For example, in the '89 issue page 338 starts the article which gives the typical E vs. time and I vs. time curves for nuke bursts (50kv/m in a 5-10 nanosecond pulse!!!). Basically you can kiss most of your non-shielded electronic equipment goodby if this ever happens.
