Would the grain show up in digital pictures as well or only on film? I know why it appears on film but the gnomes that work my cell phone camera won't give me a straight answer.

I’m not even sure it would show up on film either. But for CCD cameras (aka phone cameras and basically all modern cameras), 350 americium buttons buttons from a smoke detector in a wide “stew” that far away would produce nowhere near enough ionizing radiation to do that. On top of it, americium-241 is an alpha emitter, meaning that even if alpha particles reached the lens, the lens itself would block a good amount an alpha. This video gives a demo of a CCD without protection over it with americium and other various emitters :)

Aren't CCDs going the way of the dinosaur even in phones now? I thought the whole industry had more or less shifted to CMOS sensors now?

Very cool video regardless though

Way to bust that with reality! Kept the fact checks coming!
