|AGREEMENT STATE REPORT - LOST IODINE-125 SEED
The following information was received from the State of Georgia via email:
"On June 29, 2018, it was brought to the [Piedmont Fayette Hospital Radiation Safety Officer's] RSO's attention that a radioactive seed containing 62 microCuries of Iodine-125 was unaccounted for and could not be located. The seed was manufactured by Best Medical International, Inc., Model 2301. The physical form is a double wall titanium tube containing a tungsten x-ray marker that is coated with I-125. The source serial/lot number is 45876A-26. The source was calibrated at 100 microCuries on 5/11/2018. On the morning of the seed implantation procedure, 6/27/2018, the source measured at 62 microCuries in the dose calibrator in the hot lab.
"The seed had been used for localization of a breast lesion. Tissue was extracted from the patient and the specimen was reported to have contained the seed at the time of specimen radiography. Following this radiography procedure, the seed appears to have been lost. All efforts were made by staff on-site to locate and search for the seed in all possible locations, with no success. The patient was brought back in for radiology procedures to ensure that the seed was not still contained in the patient. Results of x-rays showed that the seed was not present in the patient. According to the RSO, it is likely that the seed was disposed of along with the trash collected after the procedure, or possibly washed down the floor drain in the specimen radiography room.
"According to the RSO, this is a best guess as to the fate of the seed. No individual members of the public or staff were likely to have been exposed to significant doses of radiation, based on the available information submitted to EPD [Georgia Environmental Protection Division]."
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.
