Narrative:

Flight was airborne at XA55z; I was notified at approximately XD15z/[date] about a dangerous goods shipment that was boarded; but not properly documented. Preliminary load had no dangerous goods listed; so crew wasn't looking for any dangerous goods information. Sent the dangerous goods information to the crew: 1 pc; 63 lbs; UN2915 [radioactive material; type a package]; T.I. 1; medical shipment containing sr-82 [strontium-82]. Loaded in bulk pit 51. Discussed with crew and will continue to destination.
