The calcareous alga, Halimeda, was the one most commonly
sampled at the various islands.
Pigure 14 shows that the
absolute levels of radioactivity were nearly untform from
island to tsland. The highest levels and the steepest decline
were found in samples taken at Leroy. Variability was low
because nearly every point is an average of several samples.
At Belle the points fall in a curve, nearly level at first,
steepening to a maxinmum at 100 to 200 days, and then again
leveling. This is the most frequently observed pattern of
deviation from linearity noted throughout the survey.
