A fairly clear picture was formulated as to what the Atoll should be like at the present time. Examination of reports from the laboratories, LLL and LASL, enabled us to estimate what radionuclides should be present as a result of the composition of nuclear devices and any experiments which were performed as part of the detonations. These are listed in Table.1. The quantities of "environmental" materials, structural steel, concrete, wiring, pipe, etc., were also determined and helped to establish what debris should have remained after a shot. This information engendered questions on the ultimate disposition of these materials after the tests, stimulating further search efforts. The operations reports made to the Test Manager indicated fallout patterns for nearly every event. From these, as a crude but reasonable effort to develop an idea of residual conditions, the Atoll's islands were graded as a function of the reported fallout insult (measured exposure rates) corrected to Htl hour past detonation. is shown as Table 2. The resulting gradation This crude attempt proved to be reasonably accurate, and a useful planning device. Radiological Safety Reports made during and after the several test operations prompted more questions and consternation than answers. These reports indicated some acute radiological problems which were subsequently corrected, such as serious alpha contamination, decontamination activities, radioactive debris/waste disposals, etc. Unfortunately, these reports failed to provide sufficient detail to determine, in all cases, the eventual fate of the radioactivity itself, where it was disposed of--land, lagoon or sea, and how or how well.
