. a -3- C As an example of the complex radiological situation which exists.on -nicetok, ome island, Puwit, is show in Figure 6 with a plot of gam exposure rates on that island. Containination from eight tesis om Auait is measurable today. An early preliminary survey has contiimed the presence of a plutonium-bearing, sand layer outcropping on the ocean side -€ the tslind, aad tha existence of solid plutonium-bearing chunks, grains, and other particulates en the island suriace and car surface Earth and debris moving activities ducing and after test onerations have resulted in a complex radiological situation in which adjacent areas may be quite different as to levels and vertical distrisution of yadioactivity in soil. Data available to cate indicate than tadiclosic f contamination is less severe on other island 3s but is sufficient to pose a considerable problen.
