The following was received from the California Department of Public Health, Radiologic Health Branch via email: For additional information go to ĪGREEMENT STATE REPORT - LOST GD-153 LINE SOURCES 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. 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. THIS MATERIAL EVENT CONTAINS A 'Less than Cat 3' LEVEL OF RADIOACTIVE MATERIAL UCSD sent health physicists to the recycling center to search for the missing package." The expected exposure level is close to background radiation level outside of the shielded pack. The seeds are sealed in a shielded, sterile pack. The pack contains approximately 6-7 I-125 medical brachytherapy seeds with combined activity of 2.3 millicuries.
The cardboard box was taken away by environmental services staff and has possibly been taken to the on-campus recycling center. The medical physicist removed 3 packs and set the packing box outside for recycling, believing it was empty. "A medical physicist at the Moore's Cancer Center at UCSD received a box that contained 4 packs of I-125 sealed sources instead of his expectation of 3 packs. He also reported the loss to the CA State Warning Center (control no. "The Radiation Safety Officer for UCSD contacted the Radiologic Health Branch regarding the loss of I-125 sealed sources.
