It depends on which body part they wish to be scanned. these isotopes are specific, and will go to the tissues/organs they are will be scanning =)
nuclear medicine procedures are very safe. a patient receives an extremely minute amount of tracer, just enough to provide accurate diagnostic information. the radiotracer remains in the body through natural bodily functions. drinking plenty of fluids will help clear the tracer from the patient's body.

I suppose they know mainly through experimentation, but also such an isotope must have a really, really small half-life, we're talking minutes, hours, or days. Anything more would be incredibly dangerous. I'd go with half lives ranging in the minutes to hours. keep in mind that even alpha particles, which can be stopped by a sheet of paper, can reek havoc inside a body. Let's not forget that it must also be a liquid, since otherwise it would not be able to be injected. Lastly, it can't be toxic, like polonium 210, which was used to kill that ex-KGB spy.

Each isotope has a radio active marker. Don't worry your doctor will not poison you like an ex KGB spy who just spoke against Vladamir Putin, the Premier of russia. Good luck.

As with all things: Experimentation
