equ ATOMIC ENERGY COMMISSION RADIOBIOLOGICAL SURVEY OF BIKINI LAGOON Memorandum from the Division of Biology and Medicine For some time, Dr. Lauren R. Donaldson, Head of the Depart- ment of Applied Fisheries, University of Washington, Seattle, Washington, has been studying the effect of water-borne radio- active materials on marine life. This study has included the ef- fects of effluent liquid wastes at Hanford on salmon and trout and the tolerance of these fish to other forms of radiation, A considerable amount of valuable information has been obtained from these studies, Dr. Donaldson has been interested in the effects of an atomic explosion on the marine life in exposed waters and, cordingly, of 1947, ac- carried out an exhaustive survey at Bikini the summer It was evident that there was considerable concentra- tion of the radioactive materials by certain forms of marine life, It is felt that a follow-up survey at Bikini is strongly indi- cated with a survey of Eniwetok Atoll, This action has been ap- proved by the Advisory Committee for Biology and Medicine. cordingly, Ac- arrangements have been made through the Division of Military Application for support by the U. S. Navy of this survey and the attached document concerns their activities in developing this survey.
