Description/Abstract:
A WORLD-WIDE NETWORK OF GUMMED FILM STATIONS WAS ESTABLISHED TO MONITO R FALLOUT FOLLOWING OPERATION CASTLE. ALTHOUGH METEOROLOGICAL DATA WER E POOR, A GENERAL CONNECTION OF TROPOSPHERIC FLOW PATTERNS WITH OBSERV ED FALLOUT WAS EVIDENT. THERE WAS A TENDENCY FOR DEBRIS TO REMAIN IN T ROPICAL LATITUDES, WITH INCURSIONS INTO THE TEMPERATE REGIONS ASSOCIAT ED WITH METEROROLOGICAL DISTURBANCES OF THE PREDOMINANTLY ZONAL FLOW. AS THE SEASON ADVANCED, SUCH INCURSIONS BECAME MORE EVIDENT. OUTSIDE O F THE TROPICS, THE SOUTHWESTERN UNITED STATES RECEIVED THE GREATEST TO TAL FALLOUT, ABOUT FIVE TIMES THAT RECEIVED IN JAPAN. THE TOTAL WORLD- WIDE FALLOUT UP TO JULY 1, 1954, FROM THE CASTLE SERIES OUTSIDE OF THE IMMEDIATE TEST AREA, IS ESTIMATED TO BE ABOUT OF THE TOTAL FISSION AC TIVITY PRODUCED. THE MAXIMUM FALLOUT ON ANY DAY AT AN INDIVIDUAL STATI ON IN THE UNITED STATES, CORRECTED TO SAMPLING DAY, WAS 200,000 D/M/FT -2. IT IS CONCLUDED THAT THE PROBABILITY OF EARLY FALLOUT IN INHABITED REGIONS WOULD BE REDUCED BY HOLDING PACIFIC TEST SERIES IN THE WINTER MONTHS.
