The State provided the following information via facsimile:
Prior to a scheduled patient treatment, the RSO at Methodist Medical Center was performing QA testing on the Nucletron-Oldelft Corp. Model microSelection-HDR remote afterloading device. The device utilizes a sealed source containing 10 curies of Iridium-192 to be used for treatment of cancer in humans. The sealed source would not retract when the RSO tried the emergency retraction button at the control console. Following the emergency procedures, the RSO manually retracted the sealed source into the HDR afterloader unit. The RSO estimated it took three seconds to return the sealed source to its shielded position. Nucletron Corp. was immediately notified of the malfunction by the RSO. Nucletron Corp. called DRH to request reciprocal recognition of its Maryland license and an authorized service person arrived at the licensee's facility on 12/28/06. The circuit board was found to be faulty and was repaired. After repair, the required safety functions of the system were tested and found to be functioning as designed. The licensee will complete a written report and submit to the State.
