Description/Abstract:
THIS REPORT DISCUSSES IN DEPTH THE DIFFERENCES IN DISTRIBUTION OF STRA TOSPHERIC FALLOUT RATES FROM POLAR AND EQUATORIAL EXPLOSIONS. A BRIEF SUMMARY OF CURRENT THEORIES ON THESE DIFFERENCES IS GIVEN. VARIOUS MOD ELS OF TESTING ARE USED, INCLUDING STRONTIUM 89 AND STRONTIUM 90 RATIO S, CONCENTRATIONS OF FISSION PRODUCTS IN SURFACE AIR DATA, AND DATA FR OM THE DEPARTMENT OF DEFENSE PROJECT ASH CAN RELATIONG TO STRATOSPHERI C STRONTIUM 90 AND CESIUM 137/STRONTIUM 90 RATIO. FOREIGN SOIL MEASURE MENTS TAKEN IN 1958 ARE ALSO CITED AS WELL AS FALLOUT DATA TAKEN IN FO UR U.S. LOCATIONS AFTER THE 1958 RUSSIAN TEST SERIES. TUNGSTEN 185 AND CARBON 14 DATA DISCUSSED. IT IS CONCLUDED THAT RISING AIR CURRENTS RE DUCE STRATOSPHERIC FALLOUT NEAR THE EQUATOR. THE RESIDENCE PERIOD OF P OLAR STRATOSPHERIC FALLOUT APPEARS TO BE SHORTER THAN THAT OF EQUATORI AL FALLOUT. DATA COLLECTION MUST CONTINUE TO FURTHER SUBSTANTIATE THIS CONCLUSION.
