Vibranium does produce at least some form of radiation, or at least has a similar effect: It produces vibrations that cause other metals to shatter. However, the kind that Cap's shield is made from, the kind from Wakanda, is somehow the oposite of that and instead absorbs vibrations. I don't know if that's explained. So, going with that, its possible Vibranium's atomic number is just REALLY high and as such has a different effect. Although, I love how there's another science nerd trying to figure this out.
