| WASHINGTON AGREEMENT STATE REPORT - LOST AND FOUND RADIOACTIVE MATERIAL|
The following information was received from the state of Washington via email:
"Swedish Medical Center notified the state of Washington that a lead pig, containing 50 mCi (1.86 GBq) of Y-90 Sir-Spheres, was picked up for lead recycling. When the recycling company (Stericycle) came to collect all the lead pigs, a tech let the company into the waste room to collect the pigs not knowing that one of the pigs contained the Y-90 material left over from a treatment on Friday the 19th of April 2019. On April 23rd, the RSO [radiation safety officer] was reviewing the lead disposal paperwork and realized the material was sent out with the other lead pigs and notified the State. The RSO called the recycling company and was told the pigs were still in a drum and had not been processed. They will be returning the drum to the medical center on April 24th, 2019 and the RSO will notify the State when it arrives."
WA Event Report ID No.: WA-19-014
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.

Note: This device is assigned an IAEA Category 3 value based on the actual radioactivity of the source, not on the device type. (Reference IAEA RG-G-1.9)
