(Operation
During this series,
plant samples were collected from various islands of the atoll
as well as in July 1957, one year later.
The gross beta radio-
activity of these samples is presented in the Appendix Table B.
The results of gamma spectrum analyses for specific radioiso-—topes present in some of the samples collected in 1956 were re-
ported in 1957 by Lowman, Palumbo and south (16) |
METHODS
The beach magnolia (Scaevola sp.*)
was chosen as the
principle plant for study because of its widespread occurrence
in the central Pacific Islands; six other species also were
studied.
In order to establish the levels of radioactive con-
tamination from previous tests,
samples of plant tissues were
collected before the detonation.
The plants were staked,
labelled, measured and photographed.
After the detonation,
observations and measurements were made of the plants and
photographs were taken.
Samples to be used for the determin-—
ation of radioactivity were taken
