On January 21, 2013, a patient was undergoing a radioactive procedure using a 275 microCurie
I-125 seed as well as a resection procedure for a breast tumor. The seed was implanted on the surface of the skin and taped into place. During post-surgical clean-up after the resection procedure was performed, the
iodine seed was lost. It is believed it was removed with the tape and thrown away as medical waste.
After discovery of the loss, the patient, her car, her home and her clothing were surveyed with negative results. The surgical suite and all bedding and gowns used were surveyed with negative results. The surgical waste had already been removed by the time the suite was surveyed.
The licensee believes the seed is in the local landfill and has considered it to be 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.
