The Licensee reported by phone that at 2:30 PST today a package of returned and depleted implant seeds containing Cs-131 with a 9.7 day half-life was found damaged upon receipt with some of the contents missing. The package was to have contained 15 seeds that were returned from a customer on the east coast. When the package arrived, the licensee upon receipt inspection noted the package had a hole in it that had been repaired with tape. The receipt inspection also detected higher than expected dose rates at slightly less than 1 mr/hr contact with the package. The package was taken to a controlled area suitable for bio-hazard work and opened by the RSO. The package was opened and discovered with loose seeds in the box. 11 seeds were recovered, 4 seeds are missing. An Isoray facility survey was performed between the receiving area and the controlled area where the package was opened. No additional seeds were located. The sender of the package is being contacted as well as the RSO for FedEx. Highest dose rate on contact with a single seed was 1 mr/hr. The seeds were reported to have aged seven half-lives as of this day and at 1/100th of original strength. The Licensee will update our office [the State of Washington] with additional information when it comes available. | The Licensee reported by phone that at 2:30 PST today a package of returned and depleted implant seeds containing Cs-131 with a 9.7 day half-life was found damaged upon receipt with some of the contents missing.
