Whilst I suspect you're taking the piss, I wonder if you could you induce https://en.wikipedia.org/wiki/Cosmic_ray_visual_phenomena without receiving a medically serious dose of radiation?It's a joke, apologies I couldn't resist. Some art forms and certain works of art are genuinely dangerous [0].
Regarding cosmic rays, I thought it was caused my massive particles, and being able to produce them artificially would be a considerable scientific feat - its artistic relevance would pale in comparison.

An old chemistry teacher of mine used to use an old TV screen as a cover for potassium+water reactions, it was about an inch in thickness.
