one must know or have estimates of the areas to be used for housing and villages, for growing pandanus and breadfruit, for growing coconut, and for raising domestic animals. Figure 1 shows the Enewetak Atoll Land Use Plan as presented in the Enewetak Atoll Master Plan. Of the northern islands only Enjebi (JANET) is expected to be a residence and agricultural island. Aej (OLIVE), Lujor (PEARL), Amon (SALLY), Bijile (TILDA), Lojwa (URSULA), and Alamebel (VERA) are intended to be used as apricultural 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 ft", assuming an averape housing area to be 200' x 200' in size), a commmity center (200,000 £7), subsistence acricultural. areas (1,100,006 ft’), and commercial agricultural areas (7,300,000 ft"). In order to get an approxination of the amount of soil that would have to be removed to bring about a piven dose reduction, one needs to determine the three dimensional distribution of the radioactive contamination. Figure 3 shows the average 905, activities (pCi/pm) in soil samples collected to a depth of 15 cm on JANET. Appendix II of Nvo--140. Similar figures for 13766, 6000, and 239 5y may be foun: 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-149. 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. In addition,
