    Isn’t the blue glow only present under water (or other transparent medium with a similarly high index of refraction)?

      It’s technically slightly visible in air; if actually visible at all in air it means the level of radiation is ludicrously deadly

        It’s not so much that it’s visible in air, it’s just that your eyes have water in them

        So yeah, if you can see Cherenkov radiation outside of a pool of water, then that means the only thing attenuating the radiation is your eyeballs
