villages, for growing pandanus and breadfruit, for growing coconut, and for
raising domestic animals.

Aej (OLIVE), Lujor (PEARL),
Amon (SALLY), Bijile (TILDA), Lojwa (URSULA), and Alamebel (VERA) are intended
to be used as agricultural islands, and the remainder (ALICE, BELLE, CLARA,
DAISY, IRENE, KATE, LUCY, MARY, NANCY, and WILMA) as food gathering and picnic
islands.
Figure 2 shows the land use plan for Enjebi Island (JANET), including
14 housing areas (560,000 et’, assuming an average housing area to be 200'
x 200' in size), a community center (200,000 ft’), subsistence agricultural
areas (1,100,000 £7), and commercial agricultural areas (7,300,000 ft’).
In order to get an approximation of the amount of soil that would have
to be removed to bring about a given dose reduction, one needs to determine
the three dimensional distribution of the radioactive contamination.
Figure 3
shows the average 905, activities (pCi/gm) in soil samples collected to a
depth of 15 em on JANET.
Appendix II of NVO-140.
Similar figures for 13766, 6000, and 239bu may be found t
In addition to the 15 cm deep samples, radioactivity
distribution as a function of depth ("profile samples") was measured in
fourteen locations on JANET.
Data from these profiles are presented in
Figs. B.8.2.a-n of Appendix II of NVO-140.
Inspection of these profiles
indicates that, on the average, about 40 cm of soil would have to be removed
to reduce the activity in the top 2 cm layer by a factor of 10.
