Dunning, Chief, Radiation Kffeots of Weapons Br., DMA SURVEY OF EWIAETOK DSLaw SYMBOL: DBM: REw This is in reference to our telephone conversation of Friday, September 27, 1957, Recently, it has come to ny attention that about 10 of the people rehabilitated to Rongelap Atoll have establishnd permanent living Quarters on the Island Eniastok, It was our understanding when Ceveloping the radiological and biological data, resulting in the recommendation by the Atomic Energy Commisaion that the Rongelapese Sos eperesey eden could be returned to their home island, that the permanent abode for all would be on Rongelap Island. Fram past data 1% could be inferred that Entaetok Island has a greater contamination than Rongelap Ialand tut good data are lacking for Eniastok. It in imperative that we cbtain the pertinent data on contamination of Enxtaetok Island at the sarliest possible date. We need to assure cerselves and also to be in a defensible position if the question abould arise in the United Nationsa elsewhere. The collection of gsoch information is a responsibility of cur Division. However, those in charge of this progras do not feel that a survey om be made before Decexber 1957. The only other solution that I can think of is to request the Division of Military Application that they ask the Eniwetok Office tO make a gamma dose rate survey similar to the one of mads on Rongelap Island in dune 1957, just pricr to the return the Rongelapese. I recogn'se this iz not ap adequate survey, but o = it will give us some information. mn were faced with a similar situation in June when ee ec to learn that a resurveeyy was net planned until surpris sn we wereMorde } aske d the after the return to Rongelap Island.
