of 200 feet. The ground level dose rates were all found to be less than 0.3 mr/hr on BRAVO + 1 Day. Of the 13 islands surveyed by Mr.Cassidy on the same day, the highest reading was 0.5 mr/hr. Breslin reported negative findings. I do not have any recollection of the manner in which his flight was vectored, but that should be a matter of record. Somewhere there must be a compilation of the data obtained on these over flights for subsequent tests. Thus there need be speculation as to the extent of the fallout on the Islands of the Pacific, starting with the MIKE test on November 1 1952. Note that, early on my flight of November 2, I found.no fallout on Ujelang at 0845 local time. I don't remember the meaning of "passed word to LST", but it can only mean that it was the boat on which the Ujelang inhabitants had been evacuated, and that I was asked to report to the LST that conditions were safe for their return. This is in contrast to the testimony of The Honorable Ismael John that everything was covered by fine dust, and that the inhabitants suffered from radiation effects. Incidentally, I am quite certain that HASL had located monitoring equipment on Ujelang, which would have required that the island be visited every few days for servicing purposes. As I said at the hearing, it is unlikely that any undisclosed information exists that will affect our understanding of the extent of the BRAVO fallout. However, after forty years, such documentation that does exist may be hard to retrieve except by a lot of searching at HASL (now EML), CINCPAC headquarters, and the files of the former AEC Division of Biology and Medicine to which HASL then reported. There are a considerable number of unanswered ‘questions concerning the events prior to and subsequent to BRAVO. I think these questions should be answered for historical purposes, and I have been greatly impressed with the diligence with which Ms. Linda Chase has attempted to lecate important relevant documents. If I can be of any assistance in this regard I hope you will call on me. Cordially Co hh oe co cc: Dr. Dr. Steven L. Simon LO Harry J. Pettengill, Ms. Linda Chase
