240 RADIOLOGICAL CLEANUP OF ENEWETAK ATOLL nondestructively. Sand blasting removed some of the contamination, but was generally ineffective. Washing with acid and detergents proved valueless. 3! The DOE-Enewetak Radiological Support Project (DOE-ERSP) manager was asked for advice. He recommended the following:32 a. No bunker should be demolished solely because of surface contamination. b. Radiological considerations were no reason to seal a bunker. c. Mechanical removal and pickup of easily removable material was suggested for contaminated surfaces. On 20 June 1978, the Director, DNA visited the bunker sites, examined the contamination, and went over the radiation readings in detail. Based upon the DOE-ERSP advice, he decided that the Boken bunkers did not require further decontamination and were to be left in place33 (Figure 5-18). FIGURE 5-18. BOKEN BUNKER. BOKOLUO (ALICE) ISLAND CLEANUP Bokoluo, the most westerly of the northern islands of the atoll, contains 22 acres and wasusedfor scientific observation and measurement stations during the nuclear test period. While it did not serve as a test site, some
