Description/Abstract:
STUDIES WERE MADE OF THE STRUCTURE AND COMPOSITION OF, AND THE DISTRIB UTION OF RADIOACTIVITY WITHIN, THE FALLOUT PARTICLES RESULTING FROM A TOWER SHOT IN OPERATION REDWING. TECHNIQUES UTILIZING THE PETROGRAPHI C MICROSCOPE AND X-RAY DIFFRACTION ANALYSIS WERE EMPLOYED. THREE TYPE S OF FALLOUT PARTICLE WERE FOUND. THE MOST COMMON TYPE WAS FORMED BY THE INTERACTION OF THE VAPORIZED IRON AND RADIOACTIVE ELEMENTS WITH MO LTEN CALCIUM OXIDE DERIVED FROM THE CORAL SAND WHICH WAS CARRIED UP IN TO THE FIREBALL BY ATMOSPHERIC TURBULENCE. THESE PARTICLES CONSISTED OF AN OUTER ZONE OF RADIOACTIVE DICALCIUM FERRITE SURROUNDING AN INACT IVE RESIDUAL CORE OF ALTERED CALCIUM OXIDE. THE SECOND TYPE CONSISTED ALMOST WHOLLY OF RADIOACTIVE IRON OXIDE AND APPARENTLY WAS FORMED BY THE MELTING AND OXIDATION OF PART OF THE STEEL TOWER. THE THIRD TYPE CONSISTED OF UNMELTED CORAL SAND GRAINS WHICH HAD SMALL, BLACK, RADIOA CTIVE SPHERES ADHERING TO THEIR SURFACES. THIS IS THE SIXTH IN A SERI ES OF REPORTS ON THE NATURE OF RADIOACTIVE FALLOUT PARTICLES: PART I, USNRDL-374, 28 NOVEMBER 1952; II, USNRDL-408, 1 JULY 1953; III, USNRD L-440, 24 FEBRUARY 1954; IV, USNRDL-TR-26, 17 JANUARY 1955; V. USNRDL- TR-133, 1 FEBRUARY 1957; ALL BY C. E. ADAMS.
