The
RSO for the licensee reported that a 0.337 milliCurie
Iodine -125 seed has been lost from the Parkview Health facility. The seed that is missing was used as a calibration seed for a prostrate procedure on 1/28/09. The seed was not to be part of the seeds implanted and was to be returned to a storage vial. During an inventory on 2/2/09, it was discovered that the seed was not in the vial. It was confirmed that the seed was not implanted in the patient. All areas where the seed might have been dropped or placed within the facility were checked including vacuum cleaners and trash. The licensee has exhausted its search and considers the seed lost.
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.
