A sample of coral sand was scoope2 up from the ground
“an Aomoen Island for leaching studies to determine distribution
= of activities within the fall-out particles.
The sample was
| leached once with weter and then with successive portions of
i4lute hydrochloric acid.
Data are given in Table 2.6b-2.
Weight
of total sample was 2.1453 g.
