I went through that recently for a stress test when testing for warning signs of a heart attack. Also took radioactive iodine to kill off residual thyroid cancer cells. My sister also took it to ablate her hyperactive thyroid.

I worked in that field (Nuclear Medicine) for a while...it is very good technology, helps a lot of people.

I was always proud to have a hand in a specialty where you can restore a sense of normalcy to someone’s life with a painless thing like a couple of radioactive pills that kill off cancer cells or an overactive thyroid. I enjoyed that time of my life very much. (Except for the being on call all the time, of course)

Some funny stories with radiation...:) Well, funny looking BACK at them!

One of the lab techs had that radioactive iodine treatment for her thyroid, and we had to kick her out of the lab because she interfered with the detectors we used to monitor radioactive iodine-labeled lipoproteins in our experiments. It has a half-life of about a week if I remember correctly, so she was assigned to do research in the library for a couple of weeks.
