Hi All,
 
I friend of mine had a stress test on Tuesday, heart patient, had some stents installed a few weeks back.   About a foot away from his chest, my PM 1703 Gamma Scintillator was reading over 2,500 uR/hr.   This was Saturday night, at least four full days after the procedure.
 
Is this unusual?  I thought most of those medical isotopes had very short half lives.
 
Thanks,
 
Al
