AGREEMENT STATE REPORT - FAILURE OF SOURCE TO RETRACT INTO AFTERLOADER UNIT

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."

Event Text

AGREEMENT STATE REPORT - LOST TRITIUM EXIT SIGNS

The State provided the following information via email:

"This Agency [Nebraska Health and Human Services] contacted the general licensee in November 2006 concerning their three NRD Inc. self luminous exit signs (Model T-4001, with 19.8 Curies of H-3 when shipped, Serial Numbers 24921, 24922 and 24923) which where shipped to the licensee in early 1986. The licensee discovered that in 1993 the store moved to a new location within the shopping mall. The signs were left in the original store location. This location went through a major renovation in 1993 at which time a demolition company gutted the entire store. The debris was disposed of by the demolition company. The mall's manager and the new store's representative do not know the name of the demolition company and do not know the current location of the three exit signs."

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.

This source is not amongst those sources or devices identified by the IAEA Code of Conduct for the Safety & Security of Radioactive Sources to be of concern from a radiological standpoint. Therefore is it being categorized as a less than Category 3 source
