Comment Seen in darkroom. (Score 1) 96
I process my own film and have always noticed, especially with TMAX B&W 120 rolls that - when I finish loading the film into the development spool - as I peel off the tape holding it onto the original film spool, I can see "stars" sparkle as it's peeled. Of course this is done in total darkness (no red light) and after my eyes have fully dilated in the pitch black. Also helps to not look directly at it but slightly to the side because highly sensitive rods in the eye are concentrated around the perimeter of the retina whereas colour-sensitive but not as light sensitive cones are concentrated in the middle. Haven't tried this with any other kind of tape.

BTW - Ilford makes the sticky tape you lick when you finish shooting a roll of 120 film spearmint flavoured which I think is a nice touch. Wonder if THAT's radioactive too?
