Description/Abstract:
AN ACCIDENTAL RADIATION EXCURSION OCCURRING DURING A PLUTONIUM-239 REC OVERY OPERATION RESULTED IN SIGNIFICANT EXPOSURE OF THREE PERSONNEL, O NE EXPOSURE TERMINATING IN FATALITY. RADIATION OF THE FATALLY EXPOSED PERSON WAS NONUNIFORM, AND IT WAS POSSIBLE ONLY TO ESTIMATE HIS AVERAG E BODY DOSE AND DOSE INCIDENT TO SPECIFIC BODY AREAS. HIS AVERAGE FAST NEUTRON DOSE WAS ESTIMATED AS ABOUT 900 RADS, AND GAMMA-RAY DOSE AS 3 000 - 4000 RADS. THE FAST NEUTRON DOSES INCIDENT TO THE HEAD AND UPPER ABDOMEN WERE ESTIMATED AS 2600 AND 3000 RADS, RESPECTIVELY, AND THE R ESPECTIVE INCIDENT GAMMA-RAY DOSES AS ABOUT 7800 AND 9000 RADS. A SECO ND OPERATOR RECEIVED A NEUTRON DOSE ESTIMATED AT 2.6 RADS, AND HIS FIL M BADGE SHOWED A GAMMA-DOSE OF 118 RADS. THE THIRD PERSON'S NEUTRON AN D GAMMA-DOSES WERE ESTIMATED AS 1.4 AND 31.5 RADS, RESPECTIVELY. MOST OF THE GAMMA-RAY DOSE TO THE NONFATALITY EXPOSED OPERATORS WAS ACCUMUL ATED DURING SUBSEQUENT TRIPS NEAR THE SOURCE.
