Reminds me of the radiation after Chernobyl causing flashes on the physical film: https://www.youtube.com/watch?v=KOLBEx5DBaE

Seeing visible light flashes in the scintillator was one of oldest ways how we observed ionizing radiation. It's more then 100 years old method.

"This built upon the work of earlier researchers such as Antoine Henri Becquerel, who discovered radioactivity whilst working on the phosphorescence of uranium salts in 1896. Previously, scintillation events had to be laboriously detected by eye, using a spinthariscope (a simple microscope) to observe light flashes in the scintillator."

Can anyone tell whether these exposures occurred through the camera lens (from fallout particles in the sky of the depicted scenes) or in post- (or pre-) exposure handling of the film from hot dust carried by the photographer?

		There's no reason they would preferentially travel through the lens and hit the current frame because most of the camera and film housing is about as transparent to gamma radiation as glass. Or maybe more transparent, because glass lenses in pro cameras tend to be rather bulky. So this just happened somewhere between arrival to and departure from the zone.

		They are not part of the image of the scene. They wouldn't be focused by the optics. The optics would just be a slight attenuation much like the rest of the camera housing, film reel, operator, etc. So really a summation of all the exposure types you can imagine.

The corona monitoring satellite cameras "blink" on incoming xray flares.

thank you so much for this link! I have been trying to search for footage of this phenomenon (in the pre-llm era) 10+y ago
