Some decades ago we in the EMC lab at Tandy were asked to solve a problem; the
building fire alarm was going off at fairly regular times in the then new R&D
building -- with no signs of fire anywhere. It was solved when I suggested
the security guards NOT call in while standing under the print room smoke
detector. The detectors were replaced without delay.
In a recent "lunch and learn" at work her in Michigan I cited two ways how a
strong enough field might be produced to make susceptibility problems show up.
One was the huge "Duga-3" OTH Radar (silent now,) in the Chernobyl
contaminated zone). The one I had decent (if CNN and YouTube is decent)
information about, the USSR having been reticent while it was still around,
was a puny little GSM handset that turned on a stove's oven burner and had
nearly caused a fire. At less than a foot from the controller, the field was
enough, given that US consumer electronic devices are subject to only a
"voluntary" ONE V/m immunity standard.
FWIW... the OET 65 (and equivalent ICNIRP) limits are higher.

In the hardware store, when those guys (firemen) would come in, we
would use
their radios to light up 4' fluorescent light bulbs. That was a long time ago,
but it still made me wonder even back then
