-the Hawaiian Islands during the entire period.
Analysis of these
samples was accomplished at the Public Health Laboratory, Honolulu,
Hawaii.
Preoperational Samples
Radioactivity was detected in samples collected during the
preoperational period.
Representative findings are presented in
Table I for water, milk and food samples.
Operational Samples
Samplee collected during the operational period were for the
most part from the sampling stations.established on the various
islands of the area.
Tables II and ITI summarize findings for
gross beta air activity, precipitation and drinking water.
It can
be seen that gross beta activity in air was low during the entire
period of the operation.
However, samples of precipitation gave
relatively high gross beta readings which are reflected in the
drinking water samples.
The levels of radioactivity in native foodstuffs during the
test operational period were found to be about the same as that in
preoperational ‘samples.
Samples of grass ana scayola were Pound
to contain high levels of fission product activity.
The highest ARCHIVE:
level of gross beta activity detected in grass was 135,000 puc/ke
for a sample obtained on July 11, 1962, at Rarotonga. Since the
gross beta activities in both the grass and drinking water samples
were the result of fresh fission product fallout, the activities
decreased rapidly with time.
