The following was received from the
Florida Department of Health (Bureau of Radiation Control) via email:
At around 2020 [EDT] this evening, [the licensee] reported a lost radiography source from the Nuc-Med department.
It was confirmed as missing from the lead pig this morning by a PET-CT tech after performing a [quality control] QC check on the camera. The PET-CT tech believes that they put it in their pocket yesterday afternoon after they were finished using it, instead of putting it back in the pig. [The] licensee reports to have used four detectors in the work area, and in the PET-CT's car and residence, but the source is still missing.

THIS MATERIAL EVENT CONTAINS A 'Less than Cat 3' LEVEL OF RADIOACTIVE MATERIAL
Sources that are "Less than
IAEA Category 3 sources," are either sources that are very unlikely to cause permanent injury to individuals or contain a very small amount of radioactive material that would not cause any permanent injury. Some of these sources, such as
moisture density gauges or thickness
gauges that are Category 4, the amount of unshielded radioactive material, if not safely managed or securely protected, could possibly - although it is unlikely - temporarily injure someone who handled it or were otherwise in contact with it, or who were close to it for a period of many weeks.
