Fullscreen this video from yemen and note the scintillations on the CCD cell phone camera after the bunker buster explosion (not during the explosion, those are flying sparks). These are charged particles impacting the camera, protons from decaying neutrons, I suppose. But of course that’s crazy talk. https://en.wikipedia.org/wiki/Nuclear_bunker_buster
Here are several other videos apparently from the same explosion. See especially the one that starts at 0:50.
