We cannot acknowledge the help and counsel of all those who aided us, but of especial help were the members of the AEC Division of Biology and Medicinestaff in the Washington office. The AEC personnel at Hanford Engineer Works, in particular Kenneth Englund, were most helpful. The administrative staff of Operation Ivy, especially Duncan Curry, Jr., and Col P. L. Hooper, provided the support needed to carry out the operations in the field. CDR J. H. Barker, Jr., USN, acted as liaison officer; his services were invaluable in the preoperations planning, procurement of supplies, shipping of material, and arrangement for transportation of personnel and equipment. The officers and enlisted men of the USS Oakhill (LSD-7) supplied the necessary assistance for our uperations and in many ways made our work and stay in the area enjoyable. To them we acknowledge our thanks. i
