(d) The Shielding Effectiveness (SE) (depending upon the polarization of the field) from
Figure l-84 is either
SE S=1 = 35dB
SE S=2 = 25 dB.
Use the lowest SE (25 dB) for design purposes.
If these calculations or estimates indicate a need for additional shielding, incorporate the shielding
into the design of the structure, and schedule its installation at a time in the construction phase when it can be
done most economically.
