During the first United States nuclear test on 16 July 1945, electronic equipment was shielded due to Enrico Fermi's expectation of an electromagnetic pulse from the detonation. The official technical history for that first nuclear test states, "All signal lines were completely shielded, in many cases doubly shielded. In spite of this many records were lost because of spurious pickup at the time of the explosion that paralyzed the recording equipment."[2] During British nuclear testing in 1952–1953 there were instrumentation failures that were attributed to "radioflash", which was then the British term for EMP.[3][4]

And yet smoking causes lung cancer, even in people who don't smoke. There can't possibly be any connection between exploding nuclear devices in the atmosphere and lung cancer, oh no.
