They are powerful. I have a tape of Gloria Estevan and the Miami Sound Machine that has a crackle on it and I was told that this was caused by Fidel Castro facing Florida pulling Scotch Tape to lower the quality of any Cuban exiles' musical recording :D
As already indicated there must be a vacuum to establish an environment where charges are large enough to evoke X-rays.

I have noticed the 'tape glow' phenomenon too but I always thought it was static electricity, which shows how much I know, dunnit. :-)
Re: Does Tape Glow?
There's a very simple solution to this: don't pull the tape from the film but pull the paper backing from the tape and fold back the tape over the film: that also gives you a much stiffer end to start spooling the film on the reel (I always start from "the other side"). Works great with Jobo reels, but I never tried with Paterson or others.

when i don't have an enlarger handy to do contact prints,
i usually pull the tape off a 120 roll really fast and chomp on a wintergreen lifesaver ..
it works pretty well

I always fold over the tape on 120 as it goes into the end of the reel too. Someone is going to tell us why that's a bad habit, but so far so good.
I suppose if any paper fibers stick to the tape, they might come off during processing and stick to the film.

When I was taking the black tape off a bulk spool canister, I was amazed at how bright the green glow was, and glad the tape was on the outside with the film inside!
Hm… I wonder…
On my first roll of Delta 3200, I struggled mightily with the tape. It resulted in me worrying the film end quite a bit. I've been wondering if the fogging on the tape end of the film, covering about a frame and a half (6x6cm frames; the length was about the length of film still to be loaded onto the plastic “walking” reel), was an artifact of the tape struggle, the film torsion, or something else.
