| Title | Agreement State Report - Missing Sr-90 Eye Applicator Source |
| Event Description | Licensee reported to Radiologic Health Branch-Granada Hills (RHB-GH) that it had discovered one of its Sr-90 eye applicator sources (Model Manning #357, SIN pending) missing yesterday [03/16/04] from its sealed source storage C-container where it had been stored for the last ten years. The actual eye applicator was kept in its own box provided by the manufacturer. The discovery was made when the RSO was conducting a routine check for leak test/inventory purposes. This source was reportedly last accounted for about July 2003. The original assay date for the source was 8/22/79 at 31.7 millicuries (Reported to be about 17 millicuries now).
The source was stored in a locked and alarmed C-container used exclusively for radioactive material storage. A fence around it is also locked. There was no sign of a break-in. However, the licensee reported that in May 2002 there was a break-in to this storage container. The same source was at that time removed from the C-container by the intruder apparently and was later found in an outside barrel so it was recovered. Incidentally, some uranyl nitrate (or acetate?) in microcurie quantities was stolen then, too. The licensee will continue searching to determine the likely disposition of the missing source. RHB-GH suggested they notify their security people. The licensee will be providing a written report. |
