ye roughly 1.5 hrs. Radar on the Wheeling tracked the helicopter till they had the Kwajalein reef in sight. 722 returned with spare parts and the first mail. , Sample collections of coconut, pandanus, and breadfruit, from Rongelap Island went well. 30 soil pits were dug down the viddle of the island and vertical profile samples to 60 cm, where possible, obtained. Soil sampling in plant root zones began in locations where fruit was obtained. The EG&G data analysis work was reviewed. The available iso-intensity contours for gross-gamma levels plotted to scale fit the island shapes as determined by aerial aan The detected radiation is almost entirely from l The weather so far has been excellent. The sex is caim. first situation report draft was reviewed. The On September 21 two whalers were away early, about 0600. ‘ne first EG&G aerial survey mission was off at 0900. Two aerial survey missions are possible each da;, one in the morning and one in the afternoon. The terrestrial and marine survey teams are away all day, returning about 1600. Sample collection teams are averageing about 6 1/2 to 7 hrs ashore per day. The survey helicopter, 724, is getting two 4 1/2 hour survey flights per day using two groups of scientists and two aircraft crews with refueling and crew changes at noon. A gift of food was carried ashore in a sling beneath helicopter 722. There was some rain shower activity over Rongelap Atoll in the early afternoon. There is good progress and good news with the EG&G data reduction efforts. The detailed survey of Rongelap Island shows very low external gamma radiation levels ranging from 3 to 6 uR per hour. A TWX was received indicating Nat Greenhouse will make the second leg of the survey. Roger Ray indicated they could use Jay Beaufait's help on the third leg. Ashore, Dr. Grant referred.a lady patient for transport back to the hospital on Kwajalein on the next available flight. She would be accompanied by her husband and 5-year old son. On September 22, the whalers were away about 0600. Roger Ray and I made plans for a clearance meeting with the people ashore arriving at 1400 and departing at 1530. This was followed by efforts to arrange for an emergency medical evacuation of a two-month old infant that was seriously ill. Dr. Grant indicated this morning the child was comatose and asked for an immediate evacuation to the hospital in Kwajalein. The evacuation
