I had a thought while watching Back to the Future the other day. We see Marty with an 80s-era video camera filming Doc Brown inserting plutonium into the time machine's reactor. Both he and the Doc are wearing radiation suits, but the camera is not shielded. So here's my question: would the radiation from the plutonium have any effect on the magnetic recording heads in the camera? Judging by the thin suits Doc and Marty are wearing, I'd say it's likely the camera's case would be protection enough, but I'm not sure. If those suits are not accurate for the amount of plutonium being handled, then it might have an effect, right?

PS - Obviously I can't test this myself.
PPS - I also can't find whether anyone else has tested it.
