Title	Washington Agreement State Report - Leaking Cs-137 Sealed Source
Event Description	The following information was provided via email from the State of Washington: On June 26th, WSU reported that a Cesium-137 sealed source used to test operation of radiation detection instrumentation was found, by WSU staff, to be leaking. The source had recently been used at a WSU research facility. The staff noticed that two of the detectors were indicating higher than expected radiation readings after the source had been returned to storage. Subsequently, WSU staff found the radiation detection instrumentation they had been testing had become contaminated. The source appears to have been abraded during use. The source, an Isotope Products Lab, model not yet known, Serial Number 687-87-7 and its wooden storage box were taken out of service when the leak was discovered. The source and box are scheduled for disposal as radioactive waste. WSU staff are looking into the specific cause of the abrasion. WSU will then determine if additional corrective actions will be made to keep this from reoccurring. The licensee reported that surveys were performed in all areas where the source had been used and stored. Three WSU staff were found to have between 200 to 300 counts per minute of contamination on their fingers. WSU staff also found contamination levels of up to 300 counts per minute on a hand-rail and other associated equipment in the facility. Decontamination of the staff, areas and equipment was successfully performed. Notification Reporting Criteria: WAC 246-221-265, leaking source. Isotope and Activity involved: Cs-137 check source, 0.37 MBq (10 microcuries) as of February 1, 2000. Finger contamination was noted, but no overexposures should be realized. Washington State Report WA-08-046.
