Liverman, Assistant Administrator for Environment and Safety, HQ RESUSPENSION STUDIES AT ENEWETAK AND BIKINI Reference: Report by the AEC Task Group on Recommendations for Cleanip and Rehabilitation of Enewetak Atoll, June 19, 1974. . Recommendation No. /11 of the referenced documentis: "A comprehensive air sampling program should be conducted over a period of 12 consecutive months under conditions closely approximating human habitation and expected soil disturbance. This would add to the body of available information on radioactivity levels in air. This program could be conducted coincident with and in - support of cleanup operations. "| Although I do not knowthat any formal action has been taken upon the Task Group recommendations, the reference, in its entirety, has been published as a part of the Environmental Impact Statement for the Enewetak Cleanup (DNA, April 1975). Thus the reference, and most specifically Recommendation 11, is a matter of public record. Because.the recommended air sampling program is probably best characterized as a technique of radiological surveillance (as distinguished from either cleanup or rehabilitation), and because the radiological survey is agreed to be an ERDA responsibility, NV has taken some preliminary steps in anticipation of implementation of Recommendation 1]. Fortu- nately, a large body of resuspension information is available from previous studies supported by DBER and DMA. Lawrence Livermore Laboratory has performed many of these studies, and at NV's request, ,
