Cerenkov Radiation

A RadioActive! reader sent us this fascinating image of blue Cerenkov radiation from Ohio State University's research reactor:
"...attached is a photo...of our research reactor at OSU, which I took from the pool-top during operation at about 50 kW (thermal). The blue Cerenkov glow caused by photoelectrons, Compton electrons, and beta particles is evident here, but [in my opinion] is much prettier at our licensed power of 500 kW!
