Description/Abstract:
THE RADIOACTIVITY WHICH ORIGINATED FROM THE BIKINI AND ENIWETOK TESTS IN THE SPRING OF 1954 WAS TRANSPORTED MAINLY TO THE WEST, THEN TO THE NORTH TOWARD THE COAST OF JAPAN, AND FINALLY DOWN SOUTH ALONG THE KURO SHIO CURRENT BY SUMMER 1955. ACTIVITY IN CONTAMINATED AREAS WHERE ACT IVITY IN SEA WATER WAS GREATER THAN 0.1 UUC OF STRONTIUM-90 / L AVERAG ED 4200000, 19000000, 27000000 KILOMETERS SQUARED RESPECTIVELY IN JUNE 1954, MARCH - APRIL 1955, AND AUGUST - SEPTEMBER 1955. IN SPRING 195 5 THE ACTIVITY EXTENDED DOWN TO ABOUT 600 METERS BELOW THE SURFACE. V ERTICAL DISTRIBUTION OF RADIONUCLIDES MIGHT BE INFLUENCED LESS BY VERT ICAL MIGRATION AND DECOMPOSITION OF MARINE LIFE THAN BY PHYSICAL MIXIN G. A HORIZONTAL EDDY DIFFUSION COEFFICIENT OF 0.8 - 1400000000 WAS OB TAINED FROM THE TIME CHANGE OF DISTRIBUTION OF RADIOACTIVITY IN THE OC EAN.
