WebThe numbers in the table represent decibels. 20 dB= 99% shielding, 40dB= 99.99% shielding. Therefore, 4″ concrete shields less than half as much EMF as 12″ concrete. While 4″ concrete is ineffective at shielding EMF at 500MHz or 1 GHz, 8″ and 12″ concrete have over a 99% shielding rate at the same frequencies.

WebThe answer to this question is basically the same as the question for walls—no, but a thermal camera might be able to detect something inside the concrete like a pipe or radiant heating that causes a temperature difference on the surface of the concrete. Radiant underfloor heating is clearly visible under a concrete floor.
