I have a question that I'm sure one of you can answer.  It is:  what is considered a 'short-lived' radionuclide?  The US Nuclear Reagurlatory Commission considers that any radionuclide under 60 days can be decayed to background and then assigned to normal 'waste'.  The US Food and Drug administration considers any radionuclide of ~55-59 days as long lived.  Who is correct or are both???
