Did you know that BYU is radioactive? I took this picture on campus over Thanksgiving:
I'll give a prize to the first person who can identify this picture's location. (Congratulations to Robyn, the previous MCSV prize winner.)
Incidentally, I've heard from some pretty reliable sources that BYU used to have a research fission reactor, but that it's long since been decommissioned. I've also heard from a pretty reliable source that there's still a research fusion reactor in the Eyring building. Finally, I've heard that there's a 50-gallon drum of low-level radioactive waste behind the door in the picture above, but that it's pretty harmless. Don't go worrying your little head off now.
PS—I'm a fan of the "scare quotes" around "CAUTION", as well as the scary font, which seems to be the same one that's on the "For your safety, don't walk alone in this area after dark" signs on the south end of campus.
