The following information was provided by the licensee via phone:
The event is being retracted due to the following reasons. The activity initially documented as prescribed corresponded to the quantity requested from the manufacturer. This activity is intended to decay to a specific dose by the time the procedure occurs. On the day of the procedure, the prescribed dose was 110 Gy, while the dose delivered was 89.1 Gy. The difference between these amounts is less than 20 percent, thus not subject to reporting.
