Event Notification Report for December 05, 2006

AGREEMENT STATE REPORT - LOST TRITIUM EXIT SIGN

"On December 5, 2006, the licensee reported that an exit sign, currently containing approximately 5.5 Ci of H-3 was apparently lost or inadvertently disposed during remodeling of the University Library in October 2006. This sign was distributed by 'Self Powered Lighting' in Elmsford, NY (15 Ci in March 1989), Model 710-A, S/N A60. The sign was mounted in the east stairwell of the 4th floor of the University Library, and was present during the quarterly inventory July 31, 2006. During the October inventory, and while the building was being remodeled, the sign was missing. The University staff investigated, but were unable to determine the disposition of the sign. The wall where the sign was mounted was removed by a contractor during the remodeling. The RSO discussed the situation with the Construction Manager and the University's Project Management Staff to avert such occurrences during future remodeling activities. The University will notify RHB if the sign is located. The most likely scenario is that this sign was disposed with other construction debris."

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.

OHIO AGREEMENT STATE REPORT - MEDICAL EVENT - LOWER DOSE THAN PRESCRIBED

"On December 6, 2006 at 9:00 AM the Ohio Bureau of Radiation Protection received a phone call from The Urology Center, LLC Ohio License number 02200310002 reporting a possible medical event that was discovered on December 5, 2006 at approximately 12:00 PM. The licensee reported that the loading of seeds into the prostate gland was not performed properly, resulting in a total shift of the seeds to the intended treatment site. This resulted in a dose to the intended treatment site to be 40 percent less than the prescribed dose. The seeds were delivered to the prostate gland. A preliminary report is expected by 4 PM December 6, 2006. A detailed written report will be due in 15 Days. A Ohio Bureau of Radiation Inspector will perform an inspection the week of December 11."

The seeds used for the implant were I-125, curie content not known at this time. It is not known at this time if there will be any deleterious effects due to this treatment. The patient was notified at the time of the treatment.
