Description/Abstract:
ISOLATED SEDIMENT AREAS CONTAINING PLUTONIUM AND CESIUM RADIONUCLIDE C ONCENTRATIONS EXCEEDING PACIFIC OCEAN GLOBAL RADIONUCLIDE FALLOUT LEVE LS HAVE BEEN REPORTED IN THE FARALLON ISLANDS RADIOACTIVE WASTE DISPOS AL AREA, WEST OF SAN FRANCISCO. WE FIND THE TOTAL PU-239+240 AND CS-13 7 INVENTORY OF FARALLON WATER COLUMNS TO BE WITHIN GLOBAL FALLOUT LEVE LS. THE QUANTITY OF THESE RADIONUCLIDES FROM NONFALLOUT SOURCES CONTAM INATING THE SEDIMENTARY ENVIRONMENT IS UNKNOWN, BUT THEIR CONTRIBUTION TO THE TOTAL WATER COLUMN INVENTORY IS INSIGNIFICANT COMPARED WITH PRE SENT FALLOUT LEVELS. FISH AND INVERTEBRATES FROM THE DISPOSAL REGION C ONTAIN BODY BURDENS OF PU-239+240 AND CS-137 NO GREATER THAN SIMILAR S PECIES EXPOSED TO GLOBAL FALLOUT. WITHIN DEEP (2000 M) FARALLON SEDIME NTS, WE DO DIND THAT PU-238 CONCENTRATIONS EXCEEDING ANTICIPATED FALLO UT LEVELS ARE BEING REMOBILIZED TO BOTTOM WATERS. FALLOUT PLUTONIUM AP PEARS TO BE DISPLACES LATERALLY FROM THE CONTINENTAL SHELF DOWN THE SL OPE INTO DEEPER OFFSHORE WATERS. REMOBLIIZED WASTE FROM THE DISPOSAL S ITE PROBABLY IS DISPLACED IN THE SAME MANNER.
