Abstract : Integral and time differentiated incremental fallout collectors were exposed after each of the four Roller Coaster events. Each collector exposed a sticky film, two microscope slides, and a planchet. The planchets were alpha radioassayed in the Project 5.1a field laboratory and served as an index for those stations which sampled significant fallout. The sticky films and microscope slides selected for subsequent radiochemical analysis and special particulate studies, respectively, were chosen on the basis of the planchet radioassay. Deposition contours are presented derived from the planchet activities. Soil cores were taken before and after each event to represent high-, intermediate-, and low-level deposition areas. Only the 0- to 1/2-inch fraction of the core was reserved for subsequent analyses. (Author)
