...technitium-99. (This is for a triphase bone scan.) The half life is six hours, so in a day I'll be back to normal background; in the meantime I shouldn't try to fly at a commercial airport.
Naturally this got me wondering about the medical supply of an isotope whose half life is six hours. El Camino Hospital probably has a moly cow. I get to go back for the bone portion of the scan in a couple of hours, so I'll ask.
I love asking medical people about things. Techs either love me or hate me. :-)

Re: I've probably told this story before...
But Landau & Lifschitz were the inscrutable ones. Mostly, IMO, because Landau was so brilliant that even after Lifschitz translated down to mortal-speak for him, the derivations were still surpassingly compact. The upside was that e.g. their CM text was a tiny fraction the size of anyone else's, and you felt like you had really accomplished something by the time you worked through the derivations.
I recall wandering around the UNC campus feeling affinity with the Incredible Hulk after my bone scan. Since our research group collaborated with the radiology folks on medical imaging stuff, they were happy to give me a copy of my raw dataset to play with afterwards.
