Description/Abstract:
INTEGRAL AND TIME DIFFERENTIATED INCREMENTAL FALLOUT COLLECTORS WERE E XPOSED AFTER EACH OF THE FOUR ROLLER COASTER EVENTS. EACH COLLECTOR E XPOSED A STICKY FILM, TWO MICROSCOPE SLIDES, AND A PLANCHET. THE PLANC HETS WERE ALPHA RADIOASSAYED IN THE PROJECT 5.1A FIELD LABORATORY AND SERVED AS AN INDEX FOR THOSE STATIONS WHICH SAMPLED SIGNIFICANT FALLOU T. THE STICKY FILMS AND MICROSCOPE SLIDES SELECTED FOR SUBSEQUENT RADI OCHEMICAL ANALYSIS AND SPECIAL PARTICULATE STUDIES, RESPECTIVELY, WERE CHOSEN ON THE BASIS OF THE PLANCHET RADIOASSAY. DEPOSITION CONTOURS A RE PRESENTED DERIVED FROM THE PLANCHET ACTIVITIES. SOIL CORES WERE TAK EN BEFORE AND AFTER EACH EVENT TO REPRESENT HIGH-, INTERMEDIATE-, AND LOW-LEVEL DEPOSITION AREAS. ONLY THE O- TO 1/2-INCH FRACTION OF THE CO RE WAS RESERVED FOR SUBSEQUENT ANALYSES.
