The Department of Defense led the radiological cleanup of Enewetak Atoll in the Marshall Islands. The combined federal effort cost about $100 million and required an on-atoll task force numbering almost 1000 people for three years 1977-1980. The departments of Defense Energy and Interior were involved in this project. The DOD organized three separate efforts in support of the cleanup: Removal and lagoon-dumping of uncontaminated debris and structures removal and crater-entombment of radiological contaminated debris and structures and excision and crater-entombment of radiological contaminated soil from the islands. This document is not listed/identified on the ENEWETAK ATOLL CLEANUP DOCUMENTS web page which is an official U.S. Government web page supported by the Defense Threat Reduction Agency. This chapter discusses Operation Sandstone Rehabilitation and Construction Activities Operation Greenhouse Operation Ivy Operation Castle Operation Redwing Operation Hardtack Moratorium and provides a Summary of Test Effects. There is a discussion of the Effects of Test Program on 26 individual islands. There is a discussion of the effect of Atoll experience on cleanup. and the final portion addresses Enewetak Interim 1958-1972 and Projects Hues Pace and Expo. An example of the information content is from pages 31 and 32: "Fallout from 16 events caused Eleleron to be ranked second of all islands of the atoll in H-1 hour exposure having accumulated 10643 R/hr. Most of the land mass receiving this exposure has been blasted or eroded away. Soil sampling showed surface activity to be relatively low and the one profile sample displayed a homogeneous distribution with depth this being considered to be the result of hydraulic influences."
