| Title | Radioactive Source Lost in Shipment |
| Event Description | The following information was provided by the New York State Department of Health via email:
New York State Department of Health received a phone call from United Memorial Medical Center to report a Co-57 flood source that was sent to International Isotopes on January 11, 2023. This flood source was picked up by [the common carrier] and never arrived at International Isotopes. The technologist that shipped this source back checked the status of the delivery and noticed that the shipment had been delayed and noted that the location of the package was at the Rochester NY [common carrier] hub for several weeks. The technologist called [the common carrier] on March 30, 2023, and was informed that the package was determined as lost. Information on the source is below: Make: International Isotopes Model: BM01L10 (SSDR: NR-1235-S-104-S) S/N: BM01L1021298203 Isotope: Co-57 Est Activity (as of 3/30/2023): 2.66 mCi NYS Department of Health contacted [the common carrier] independently on March 31, 2023, and was also informed that the package was lost and unlikely to be recovered. 10 CFR 20 Appendix C states a value of 100 microCi for Co-57, therefore this loss is 26.6 times this value, requiring a 30-day notification in accordance with 10 CFR 20.2201(a)(l)(ii). United Memorial Medical Center has been instructed to contact New York State Department of Health with any updates regarding this package. New York State continues to monitor this event under Incident No. 1434. Provided the estimated activity as of March 31, 2023, unshielded exposure rate at one meter from the package is expected to be approximately 147.8 microR/hr, which does not constitute any immediate risks to [the common carrier] staff or workers. No further information on the device, source or incident is available at this time. Any updates to this event will be provided as soon as available. New York Event Report number: NY-23-02 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.
