This is for strictly mildly interesting material. If it's too interesting, it doesn't belong. If it's not interesting, it doesn't belong.
This is obviously an objective criteria, so the mods are always right. Or maybe mildly right? Ahh.. what do we know?

~~Pregnant women should avoid people that got a x-ray recently but dogs can have x-ray during pregnancy?~~
(edit) wrong apparently, I don't even know where I got this from
People and dogs who have been recently x-rayed are not a danger to others. They don't suddenly start giving off radiation themselves (above background levels).
My bad. For those who believe that what you put out into the universe is what you get back, remember that the converse is true as well. If you receive x-rays with an open mind, you can also emit them.
A friend had a radio isotope cancer treatment. He also built a geiger counter (for his own amusement). It was quite scary how much he set the thing off getting close to it!
Instructions were to not sleep in the same bed as anyone else for 2 nights, and limit closeness to people or pets for the same period.
I've never heard about pregnant women having to avoid people who had a recent x-ray. According to the Mayo Clinic: "The possibility of an X-ray during pregnancy causing harm to a fetus is very small. Generally, the benefits of the information from an X-ray outweigh the risks."

I think you might be confusing it with midly radioactive injections. My gf was given one to study how well her lyph nodes function and distribute the liquid. She was tol not to hang around pregnant people too long.
