The following information was obtained from the State of
Arizona via email:
At approximately 0800 [MST] on July 1, 2015, the licensee reported that two (2) 0.256 millicurie Iodine-125 seeds were potentially lost on June 24, 2015. The licensee stated that while implanting 84 I-125 seeds into a patient in the operating room, the doctor realized that one of the syringes, which was supposed to have two (2) I-125 seeds in it, was empty. The licensee surveyed the entire operating room and hot lab but did not locate the seeds. The manufacturer was also contacted in an attempt to see if the syringe was shipped to the licensee without the seeds in it.
The Agency [Arizona Radiation Regulatory Agency] is investigating the event.
The Governor's Office is being notified of this event.

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.
