The licensee reported that a
brachytherapy source/seed was lost after completion of a medical procedure. After the seed was removed from the patient, the device was improperly placed in the rack for sterilization and cleaning and it is believed the seed was lost as part of this cleaning process. Normally, the device would have been placed in a surgical bowl and moved to a flash chamber for seed recovery. The seed was a Best Double Walled
I-125 seed with a 204 microcurie source, model #2301.
There was no harm to the patient or exposures to other personnel. The licensee is continuing their investigation and will provide additional information when it becomes available.
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.
