Title	Agreement State Report - Static Eliminator Source Seal Integrity Lost
Event Description	The following report was received by the Iowa Department of Public Health (IDPH) on February 23, 2011. On February 22, 2011, the University of Iowa Environmental Health and Safety (EHS) staff discovered evidence that a Nickel-63 foil in a custom made static eliminator had lost its seal integrity. The source in question consists of two 8.951 mCi Ni-63 foils that are housed in a custom built static eliminator (2 inch diameter steel pipe with the foils glued to the walls of the pipe). The static eliminator is attached to a chamber apparatus located in a fume hood within a principal investigator's lab. The results of the leak test indicated approximately 40,203 dpm (0.0181 uCi's) of activity on a wipe taken of several areas in the apparatus housing the Ni-63 foils. EHS personnel bagged the static eliminator and returned it to EHS for disposal. The two Ni-63 sources were purchased from DuPont/Merck in March of 1995. The Principle Investigator (PI) had been conducting research using these sources since that time. The University RSO reports that the PI does not have any more of these custom devices and will be pursuing other options for research. A previous leaking Ni-63 foil was reported as NMED Item Number 100592. Iowa Incident No. 110002
