The following is a synopsis of information provided by the licensee via phone call:
On 4/15/24, a 145 microcurie iodine -125 implant seed was lost. The seed was one of four seeds to be implanted for mammography. During the exam, it was discovered that only three seeds were implanted. Licensee staff verified that the seed was not implanted in the patient. A thorough survey of the room, linens, and trash was performed and did not yield the seed. Licensee staff can not verify that the seed was present in the needle prior to the procedure.
The patient and the prescribing physician were made aware of the missing seed. No negative effect on the patient is expected.
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.
