Box 29939 — REMARKS: Honolulu, Hawaii 96820 Dear Bill: The April 1976 Radiological Survey at Bikini was a qualified success, The following trip report describes the achievements of this survey, and identifies some of the difficulties encountered by our team on this expedition. The survey team assembled in Honolulu during the week of March 29, and proceeded to Kwajalein via MAC on Friday, April 2. Our gear, which had been shipped in advance, had arrived in good condition, Ted Murawski had arranged for Lt. Col. Joseph Hayden of KMR to accompany us, and Col. Hayden's assistance proved quite valuable in light of the time constraints which developed later. The entire party proceeded to Eneu Island via C-54 charter on Sunday, April 4, The pilot flew around Bikini Atoll, making several passes over Nam Island for aerial phototraphs. However, the Polaroid photographs were of little value because of the poor camera angle. At Eneu we crossed paths with Dr. Conard's entourage which returned to Kwajalein that same day. Eneu Island All work described in the protocol was accomplished by early after- noon on April 4. The Liktanur then transported our party to Bikini Island, arriving about 1700 hr. Bikini Island Lat fr. Catchment water and sediment samples, along with "house dust" samples, were collected on April 5, These samples should prove valuable in shedding some light on the source(s) of plutonium intake by the resident Bikini population. There is considerable concern at present over the positive plutonium findings by USERDA, HASL in a pooled urine sample collected at Bikini in September 1975 by the BNL Medical Team. 0123 INFORMATION OPERATOR (516) 345-2123 3 e223& 8& || Admin. | Assistant 4 Clerk ADMINISTRATIVEOFF. . .
