The following is a summary of an email from the state of Florida:

At 1600 [EST], the [Radiation Safety Officer] RSO called to report a radiation underdose. Following the procedure, the waste was collected and measured to calculate the actual activity delivered. The actual activity delivered was 0.76 GBq, 90 percent of the prescribed treatment dose. Post procedure, during the room survey, inside the Plexiglas Administration Box a high level of activity was detected. The box was placed in double bags and relocated to the waste storage area.
