| Title | Lost I-125 Seed |
| Event Description | The following information was received from the Utah Department of Environmental Quality, Division of Waste Management and Radiation Control (the Department) via email:
On June 24, 2024, the Department was notified that on June 4, 2024, an I-125 seed for breast localization was not recovered during routine tissue processing of the tissue sample at the grossing bench or within the histology lab. The seed was verified in the tissue sample at the time of removal from the patient through both survey of the patient and a radiograph of the tissue sample. The seed was most likely disposed of either in the biohazard waste or in the non-biohazard waste. Upon discovery of the lost source, a survey of the lab with a low energy gamma detector was performed in an attempt to locate the source. The source was not found. Exposure to the public is expected to be very low or minimal. The low energy X-rays associated with I-125 decay are likely to be attenuated due to overlying waste, minimal time around the waste, and the given low exposure rate associated with the source. The material is encapsulated. Utah Event Report ID: 240004 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.
