| Event Description | The following is a summary of information provided by the New York City (NYC) Department of Health via email:
The licensee reported a loss of licensed material in quantity more than 10 times the value in 10 CFR Part 20 Appendix C. Memorial Sloan-Kettering reported via email on 5/22/2025 that a I-125 localization seed was discovered to be lost by the licensee on 3/26/2025 during an inventory. A discarded seed from a procedure done on 1/23/2025 was not able to be located. The activity was estimated as 98 microcuries on the date of use. New York Identification Number: NY250005 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.
