Description/Abstract:
DURING THE PAST SIXTEEN YEARS A NUMBER OF ATOMIC DETONATIONS WERE COND UCTED UNDER WATER, OVER WATER, OR ON LAND NEAR THE WATERS OF THE CENTR AL PACIFIC. THESE EXPERIMENTS HAVE PROVIDED AN UNPRECEDENTED OPPORTUN ITY TO STUDY THE DISTRIBUTION OF THE RADIONUCLIDES PRODUCED, IN THE BI OTA OF BOTH AQUATIC AND TERRESTRIAL ENVIRONMENTS. THE DIRECT EFFECTS OF IONIZING RADIATION UPON AQUATIC FORMS ARE VERY DIFFICULT TO MEASUR URE DIRECTLY IN FIELD SITUATIONS SUCH AS THOSE THAT PREVAIL AT OR NEAR THE TEST SITES. LABORATORY EXPERIMENTS, HOWEVER, HAVE SUPPLIED MORE SPECIFIC EVALUATIONS. RADIOACTIVE WASTE PRODUCTS IN THE SEA MAY AFFE CT THE BIOTA BY EXTERNAL EXPOSURE, I.E., BY BEING ABSORBED ONTO THE OR GANISM. SENSITIVITY TO RADIATION IS, ROUGHLY, INVERSELY PROPORTIONAL TO EVOLUTIONARY DEVELOPMENT. THE LAGOONS OF BIKINI AND ENIWETOK ATOL LS OFFER SEMI-ENCLOSED BASINS IN WHICH THE CYCLING OF RADIONUCLIDES HA S BEEN EVALUATED. IN THE OPEN SEA, THE CONTAMINATED WATER MASSES WERE FOLLOWED. CONCENTRATION OF RADIOACTIVITY BY THE PLANKTON CHANGED THE RATE OF MOVEMENT OF THE RADIONUCLIDES FROM THAT EXPECTED FROM CURRENT DISPERSAL ALONE. DETONATION OF ATOMIC DEVICES HIGH ABOVE THE SEA PRO DUCES VERY SMALL AMOUNTS OF FALLOUT.
