Description/Abstract:
THE OBJECT OF THIS STUDY EAS TO MEASURE THE RELATIONSHOP BETWEEN THE S PATIAL DISTRIBUTION OF THE RADIOACTIVE FISSION PRODUCTS AND THE RESULT ANT RADIOACTIVE FIELD IN AN ATOMIC BOMB CLOUD. DATA OBTAINED BY THE H IGH-INTERSUTY RATE METERS AND THE JET IMPACTORS LEAD TO THE FOLLOWING CONCLUSIONS: (1) THERE IS A DEFINITE CORRELATION BETWEEN THE PARTICULA TE FISSION-PARTICLE DENSITY AND THE GAMMA-RADIATION INTENSITY MEASURED WITHIN THE CLOUD; (2) THE EFFECTIVE ENERGY OF THE GAMMA RADIATION WIT HIN THE ATOMIC BOMB CLOUD IS QUITE LOW, BEING OF THE ORDER OF 200KEV; (3) THE STRUCTURE OF THE ATOMIC BOMB CLOUD RESEMBLES A CHIMNEY WITH PU FFS OF RADIOACTIVE MATTER IN THE FLUE OF THE CHIMNEY; (4) (CONT.) THE AVERAGE ROENTGEN DOSE ACCUMULATED BY A PLANE PASSING THROUGH A CLO UD OF THE TYPE TESTED IN THE DOG AND EASY SHOTS 210 SEC AFTER BOMB DET ONATION IS APPROXIMATELY 125R. THE AVERAGE CONTAMINATION ON THE PLANE AFTER PASSING THROUGH THE CLOUD IS BETWEEN 10 AND 20 R PER HOUR; NO C ONTAMINATION COUDL BE DETECTED WITHIN THE PLANE; (5) THE GAMMA-RADIATI ON EFFECTS EXTEND BEYOND THE LUMITS OF THE PARTICULATE RADIOACTIVE FIS SION PRODUCTS; AND, (6) THE VISIBLE CLOUD AND THE FISSION-PRODUCT PART ICULATE CLOUD FROM THE BOMB DO NOT COINCIDE EXACTLY; THE VISIBLE CLOUD EXTENDED BEYOND THE FISSION-PRODUCT-CLOUD IN THOSE INSTANCES WHERE DA TA WERE OBTAINED.
