Description/Abstract:
FILM BADGE DOSES ARE RECONSTRUCTED FOR SIXTEEN SHIPS AND THE RESIDENCE ISLANDS OF ENEWETAK AND KWAJALEIN ATOLLS RESULTING FROM THE SIX NUCLE AR DETONATIONS COMPRISING OPERATION CASTLE (MARCH-MAY 1954). FALLOUT FROM SHOTS BRAVO AND ROMEO WAS THE MAJOR SOURCE OF CONTAMINATION ON MO ST OF THE SHIPS AND ISLANDS. VARYING AMOUNTS OF FALLOUT FROM SHOTS UN ION, YANKEE, AND NECTAR CONTRIBUTED SOMEWHAT TO THE TOTAL DOSES OF THE SHIPBOARD AND ISLAND-BASED PERSONNEL; NO FALLOUT WAS EXPERIENCED AS A RESULT OF SHOT KOON. SHIPBOARD PERSONNEL RECEIVED ADDITIONAL EXPOSUR E FROM HULLS AND SALT WATER PIPING SYSTEMS THAT HAD BECOME CONTAMINATE D FROM OPERATING IN THE RADIOACTIVE WATERS OF BIKINI LAGOON. FROM THE RECONSTRUCTED RADIATION ENVIRONMENTS, BOTH TOPSIDE AND BELOW, AN EQUI VALENT FILM BADGE DOSE IS CALCULATED AND COMPARED TO ACTUAL DOSIMETRY DATA. AGREEMENT IS VERY GOOD DURING BADGED PERIODS WHEN THE SHIPS REC EIVED SIGNIFICANT FALLOUT. WHEN TOPSIDE INTENSITIES WERE NOT DOCUMENT ED, GENERALLY LATE IN THE OPERATION WHEN INTENSITY LEVELS WERE LOW, AG REEMENT IS NOT AS GOOD. CALCULATED SHIP CONTAMINATION DOSES OF SIGNIF ICANCE ARE IN EXCELLENT AGREEMENT WITH LIMITED AVAILABLE DOSIMETRY DAT A. CALCULATED AVERAGE DOSES FOR SHIPBOARD PERSONNEL RANGE FROM A LOW OF 0.19 REM FOR THE CREW OF THE USS LST-825 TO A HIGH OF 3.56 REM FOR THE CREW OF THE USS PHILIP. AVERAGE DOSES ON THE RESIDENCE ISLANDS OF ENEWETAK AND KWAJALEIN ATOLLS ARE 1.09 REM AND 0.32 REM, RESPECTIVELY.
