Ih’TRODUCTION
This appendix is a compilation of radiological survey results for each of the
islands in Enewetak Atoll. The information for each island includes a color aerial pho-
tograph, a series of photographs overprinted with survey data, and a set of analytical
data. It should be noted that several islands (i.e., IRENE, I’lTONNE. ELMER, FRED,
and IRWIN) have been subdivided into sections (e.g., IRENE A and IRENE B) because of
their relatively large size. In addition, it should be pointed out that the sets of over-’
prints are not necessarily the same for all islands. Thermoluminescent detectors
(TLD’s), for example, were not used on all islands. For ease of comparison and clar-
ity, the same data parameter for each island is overprinted on the same color of
photograph.
For a discussion of the techniques used in collecting the data presented on the -
photographic overprints, the reader is referred to the appropriate section in Vol. I of
this document.
A typical set of survey results is outlined below for ALICE, together with the page
and figure designation scheme used.
