Stanley, 1979 Director USDOE/PASO P. O. Box 29939 Honolulu, HI 94690 Dear Bill: This letter delineates our objectives and our requests for PASO assistance with respect to the R. V. Liktantir Voyage No. 7. This letter also supercedes that dated July 2 from Bob Miltenberger to Harry Brown. The objectives of this field trip are as follows: 1. Personnel monitoring (whole body counting and urine bioassay) at Rongelap and Utirik as part of a regular surveillance program for these atolls. Whole, body counting (WBC) at Rongelap and Utirik was last done in April 1977, and these atolls are again due for a personnel monitoring visit based on an established schedule of once every 2 to 3 years. During our stay at Rongelap, a rebuilt wind-powered electrical generator will be installed to operate our continuous air sampling equipment. An additional 10 foot tower section will be added to the wind-powered generator at Utirik in an attempt to remove it from a turbulence zone which reduces its operating efficiency. We also expect to continue our environmental sampling and diet assessment programs at both atolls. 2. Personnel monitoring at Ujelang for the purpose of establishing baseline body burdens of +3’cs, 3¥sr/90y, and other radionuclides. We have established 14 categories of personnel monitoring subjects based on parameters which we feel are relevant to internal dose assessments for the returning Enewetakese. The categories are presented in the following table:
