Radiation Participants

Radiation Participants, by Ray Larabie, is a free radiation-symbol display font that turns the alphabet into a blunt piece of hazard-era signage. Heavy black letters are interrupted by circular trefoil emblems, so the design reads less like ordinary lettering and more like warning graphics fused into the word itself; the round characters especially carry that recurring motif.

It fits posters, zine covers, club flyers, title cards, T-shirt graphics, and short logo-style headlines where a free font can bring in nuclear, industrial, or darkly comic energy fast. Keep it to brief settings: the symbol built into the letters gives monograms, cover lines, and one-word headers a direct visual hook.
