| Title | 3 Curie Cobalt-60 Source Discovered Disconnected |
| Event Description | At approximately 9:30 AM MST August 25, 2003, the Agency was informed by the Licensee that they had discovered a source had disconnected from a rod in the Process Leaching Vessel. The source contains 3 Curies of Cobalt 60 as of October 2001. The licensee has made measurements and determined the radiation levels outside the vessel are not excessive. The device is a ThermoMeasure Tech Model 5031 L SN B43. Even though the source is disconnected, because it is trapped within a sealed source guide tube, it is still secure from inadvertent removal. The estimated date for full repair is October 21, 2003. Repair will be made by the device manufacturer. The Licensee has agreed not to drain the vessel without Agency notice and approval.
The Agency continues to investigate this incident. The Agency is: ARIZONA RADIATION REGULATORY AGENCY. First Notice: 03-13 |
