was conducted near Bikini and Eniwetok Atolls by the AFL.

survey WAS conducted during the Spring 1956 test series of detonations,
relatively higher activities might: be expected.
Table Forty-five sum-
marizes some of the jate. It will be noted that the average (see
separate report) activity value for planktonis about 7,000 greater
than the average surface water value.
