To conserve space, daily fallout maps for the month of Jue are not shown. Rather, a map showing the average daily fallout for the month is given, together with the number of days for which data was available at each station. Again, the extrapola- tion is based on Nectar, and activity is shown at 100 days after burst. It is also likely that the major portion of the fallout in June originated from Yankee and al] values should be increased by about 25% to give values at 100 days after Yankee. Although the discussion of the transport of debris in the atmosphere has been confined to essentially horizontal trajectories, the actusl paths of individual radioactive particles are complex, three-dimensionsl phenomena, influenced by the fall velocities of the particles, atmospheric turbulence, rain scavenging and orographic effects. ~ 18 «
