Geiger counter for Regenstein back up

The live radiation readings from the Reg is back up and running. I took it down to use it for the Scavenger Hunt this year. The item was:

89. Find the most radioactive place you can get on campus without breaking any rules, laws, or safety regulations. Record the radioactivity level in μrad/h. [5 points. -100 points if we have to call radiation safety].
