To conserve space, daily fallout maps for the month of June
fare not show. Rather, a map showtng 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-
(tar ts Based on Nectar, and activity is show at 100 days after
Durst. It is also likely that the major portion of the fallout
un Jume originated from Yankee and sll 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 actual paths of individual radioactive particles are complex,
three-dimensional phenomena, influenced by the fall velocities of
the particles, atmospheric turbulence, rain scavenging and
orographic effects.
