The four orders contained a total of 252 seeds at a total air kerma activity level of 522.8 U. The total apparent activity is approximately 1 Ci (the actual activity is between 1 - 2 Ci). The absorbed dose from the 252 seeds would be approximately 52,280 rad (522.8 Gray). Early Tuesday morning, 6/14/2016, the Memphis hub of [the common carrier] informed IsoRay that they were unable to locate these packages, and they would not be delivered on time as contracted. They were scanned in and out at both the Pasco and Spokane airports. The Spokane flight to Memphis arrived, but [the common carrier] could not locate them. IsoRay notified the state of the loss of radioactive material that same day.
On 6/15/2016, IsoRay notified the state that [the common carrier had] found the missing shipments and are returning them to IsoRay. They were not delivered to the intended physicians.
