Warning - Radioactive Ruby

I'm radioactive! Well, at least for a wee bit longer. Don't remember what they said the half life was. Anyway, I had the PET scan this morning (no Dad, I don't have any results yet - they have to send them back to my doctor). The worst part was they wouldn't let me read while the stuff was in me, so I had to lay there for 45 minutes, but I couldn't fall asleep, no matter how much I wanted to. I was just wide awake. Then, when I was actually in the scanning tube, I almost fell asleep. Figures.
