ae es a re re a bad bed PLANNING AND OPERATIONS DIRECTIVE (NVO - 158) >, BACKGROUND The Bikini Atoll was extensively used during the 1950's for atmospheric nuclear testing, necessitating displacement of the Bikinians. The rehabilitation of Bikini Atoll and the resettlement of people on Bikini and Enyu Islands has been approved and the project is underway with approximately 80 people now residing on these two islands. The need for a more comprehensive survey of Bikini Atoll was recognized in October, 1974, following a visit to the Marshall Islands by Defense Nuclear Agency, Department of Interior and ERDA representatives. ERDA became committed to the early accom- plishment of this survey in a meeting with Trust Territory representatives in Anaheim, California, in January, 1975. Tt. PURPOSE The purpose of the 1975 Bikini Atoll Radiological Survey is to conduct a Gamma Survey which will supplement Brookhaven National Laboratory data and provide information for advising the Department of the Interior on the location of Phase II homes and to conduct a soil, plant and water sampling \|program. This planning and operations directive provides guidance and defines responsibilities for the conduct of this survey. IIt. AUTHORITY Authorization and guidance for the Bikini Atoll Radiological Survey was furnished NV per teletype from ERDA/HQ dated May 19, 1975, attached as Appendix A. Iv. CONCEPT OF OPERATIONS The 1975 Bikini Atoll Radiological Survey will include sampling of biota, soil and ground water on Bikini and Enyu Islands (see Appendix B). Specifically, soil profile and surface samples will be taken around existing structures, proposed housing sites and in agricultural areas. Skimming wells will be dug to take soil samples at various depths and to collect water samples.
