FY 1975 The Marshall Islands Radiological Safety Program was formally initiated. Funding Levels were $125,000 for operating and $20,000 for capital equipment. Staffing levels were 1.5 man years scientific and professional and 1.0 xan year technical support. Greenhouse directed the program. Arrangements were made to upgrade the BNLHPS analytical lab with the additions of a computer based multi-channel analyzer and a high efficiency GeLi detector. Greenhouse and Nelson, in a joint UWLRE/BNLIPS field trip to the Northern Marshalls in December 1974, collected environmental samples and made external radiation measurements at Rongelap, Utirik, Rongerik and Bikini Atolls. Greenhouse, Williams, and Kuehner of BNLHPS, Reilly of the State of Pen- nsvlvania, Davis of Pacific Gas and fZlectric, and Nelson of UWLRE participated in an April 1975 field trip to Bikini Atoll. They collected samples and de- fined the external radiation environments of Bikini and Enue Islands. Limited soil and vegetation sampling were done at Bikini and comparison environmental samples were collected at Wotho and Kwajalein Atolls. This field trip es- tablished the groundwork for a major interagency survey of Bikini and Enue Islands in June in which Greenhouse participated. groundwater and some vegetation sampling. This survey included soil, It was performed jointly by LLL, UWLRE, the Environmental Protection Agency, and BNLHPS. Their primary ob- jective was selection of locations for the second increment of house con- struction on Bikini and Enue Islands by the Department of the Interior.
