Implementation of these Mee res was the responsibility of the FRST under the staff supervision prove 12 HQ JTG. Radiation control personnel werethefirst persons on ot Mad, and they determined the radiation safety measures required. ation of all soil cleanup When all radiation safety and control procedures were established, the ERST controlled all entry and exit from the island. Before commencing iny operation which was likely to raise dust, such as brush removal, a prefabricated sprinkler system was assembled and used to spray water pumped from the lagoon over the worksite as a dust pallative. This system was used in all phases of soil movement from excision to stockpiling to loading and offloading boats. While absolutely necessary, this technique slowed operations because it required at least an hour to wet down the soil adequately. WORKSITE SURVEY The first party of workers normally were USAE surveyors (Figure 6-3). Surveyors used the overlay with grid reference points to lay out the soil FIGURE 6-3, USAE SURVEYOR.
