Description/Abstract:
THIS REPORT PREDICTS THE RADIOLOGICAL CONTAMINATION WHICH MAY RESULT F ROM FISSION BOMBS DETONATED NEAR THE SURFACE OF THE EARTH AND UNDERGRO UND. THE RADIATION RECEIVED IS PRIMARILY A RESULT OF THE INITIAL RADIA TION FROM THE EARLY FISSION PRODUCTS AND FALLOUT OF RADIOACTIVE MATERI AL FROM THE HIGH CLOUD. THE DISTRIBUTION OF THE FALLOUT IS DETERMINED BY CONSTRUCTING A MATHEMATICAL MODEL AND ADJUSTING THE PARAMETERS OF T HE MODEL TO FIT ACTUAL JANGLE DATA. THE MODEL IS THEN SCALED UP TO LAR GER WEAPONS BY SCALING THESE PARAMETERS IN CONFORMITY WITH EXISTING FO RMULATIONS OF EXPLOSION CLOUD DYNAMICS. THE INITIAL RADIATION IS CALCU LATED IN A STRAIGHFORWARD MANNER. THE RESULTING DOSE AND DOSE-RATE CON TOURS ARE GIVEN, AS ARE THE AREAS ENCLOSED BY GIVEN CONTOURS. IT IS CO NCLUDED THAT THE BASE SURGE AT THE JANGLE UNDERGROUND EXPLOSION DID NO T CONTAIN AN APPRECIABLE AMOUNT OF RADIOACTIVE MATERIAL, AND THIS WILL PROBABLY ALSO BE TRUE FOR OPERATIONAL WEAPONS EXCEPT AT VERY GREAT EX PLOSION DEPTHS. THE CRATERING ACTION OF EXPLOSIVES IS DISCUSSED, AND I T IS FOUND THAT ATOMIC BOMBS EXPLODED NEAR THE EARTH SURFACE SHOULD GI VE CRATER RADII WHICH SCALE AS THE ONE-SIXTH POWER OF THE ENERGY RELEA SE RATHER THAN THE ONE-THIRD SCALING APPLICABLE TO HIGH EXPLOSIVES.
