| Title | Agreement State Report - Lost Mo-99/Tc-99 Generator |
| Event Description | The following is a synopsis from information received from the state of California via email.
The California radiation protection program was notified by the licensee of a partially depleted, missing Mo-99/Tc-99m generator. The generator was shipped using a commercial carrier on October 31, 2018, from the licensee's California facility to their facility in Arlington Heights, Illinois. Near the beginning of February 2019, the licensee became aware that the generator did not arrive at its destination. The commercial carrier spent the last couple of weeks searching their facilities for the missing generator with no success and has suspended the search and considering the package lost. At the time of shipment, the generator contained 10.35 GBq (280 mCi), greater than 1000 times the 10 CFR 20 Appendix C activity for Mo-99, making it reportable under 10 CFR 20.2201(a)(1)(i). It is housed in a 12.7 kg depleted uranium shield. The package was shipped as a label category Yellow II, with a TI [transportation index] of 0.2. By November 5, 2018, the activity of Mo-99 would have decayed below the 10 CFR 20.2201(a)(1)(i) reporting criteria. By November 23, 2018, the activity of Mo-99 would have decayed below the 10 CFR 20.2201(a)(1)(ii) reporting criteria. 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.
