We recently had an individual, arriving on site for our outage, alarm our entrance portal monitors. We whole body counted him and identified peaks at 507.4 and 573.2 keV. We determined Te-121 to be the likely suspect. The individual said he had a medical treatment about a month before and had been administered I-123. This seems to be the likely source, but I don't understand how an I-123 medical treatment would result in Te-121.
Can anyone explain to me where the Te-121 would have come from? Is there another nuclide which would give us these peaks?
