BROOKHAVEN NATIONAL LABORATORY FOOLS ASSOCIATED UNIVERSITIES, INC. UPTON, L.1. N.Y. TEL YAPHANK REFER: 4-6262 June 5, 1958 Dr. Charles L. Dunham, Director Division of Biology and Medicine Atomic Energy Commission Washington 25, DBD. C. Dear Chuck: 7 ele a : A wT ‘ a I sent you a letter of appreciation for the splendid assistance given us by various groups on our mission. In the present letter I thought I might bring up some of the things that happened on our trip. Things went very smoothly as far as support was concerned. Un- fortunately, things began popping with our arrival at Eniwetok and was followed by a slight fallout. This seriously contaminated our LCU for our purposes as we found on arrival at Rongelap the following week. With the best of intentions the crew had painted the deck just prior to our getting the steel room on board, sealing in activity. We later used acid solutions and finally had paintremover flown in from Eniwetok and were able to get the background in the steel room down to about one-fifth of what it was to begin with. We could see the peaks of activity in the Rongelapese and, even though the background was undesirably high, we hope to quantitate the amounts. There were some peaks which we have not identified in addition to the prominent cesium and zinc peaks. We counted about 100 people.: We hope to be able to compare the ones that lived on Eniaetok from those on Rongelap and a few there from Ebeye. It is unfortunate that living on Rongelap for the month prior to radioactive body burdens of people living land that is of most interest. that had more recently moved the Eniaetok people had been our arrival since it is the on this more contaminated is- Fortunately there apparently had been only slight additional fallout on Rongelap atoll from the present tests to date. On arrival at Rongelap we found Mr. Neas and Dr. Hicking from Majuro and Major Ritchie from the Task Force there in regard to various claims made by the Rongelap people. It is indeed unfortunate that the rehabilitation of these people had to be disturbed by the test series. I am afraid more claims »Dased on this situation will be forthcoming. The only claim which our team was responsible for was the uprooting of two coconut trees used as mooring by the LST in March. 9002118 a erence wen _ wee - one ~
