The greatest amount of activity was found at Engebi Island,
both before and after the Mike test.
Since landings were not
made at either Bogallua or Bogombogo after the shot, there were
no collections at these islands.
In general,
the activity levels
of the land plants were lower than those of the algae collected
at the same island, but the trend is
similar.
Plants from those
islands closest to and west of the shot island contained the
highest activity.
Most of the plants at Engebi and Rojoa as
well as some at Rigili were either burned or physically damaged
after Mike shot.
Comparison of counts of damaged and healthy
leaves from Rigili plants showed no marked differences between
the two,
indicating that most of the activity was on the surface
of the leaves.
