411561 G _ GENERAL CAMM'S PRESENTATION 2172 (Le Sainnapmagy onstbing ot Dar.) Our survey has been planned and executed with emphasis on thoroughness and accuracy. Because of the AEC's unique experience in such matters, we feel it is scientifically sound and will stand on its own in any forum, including the courtroom. We feel it is of the utmost importance that prejudgements of survey results not be made in any public forum prior to the Commission's decisions and recommendations regarding radiological conditions and their impact on people. This precaution is necessary to maintain the integrity of the survey and of the related assessment of radiological impact. Any appraisal of the physical condition of the atoll must consider the total radiological dose which may be received by prospective inhabitants. The AEC's radiological survey has collected data to determine as closely as possible the distribution of radioactive isotopes throughout the atoll and in the various elements of the food chain. The radioactivity from these isotopes produce a radiological dose to man via two paths-external and internal. The external dose is derived from radiation to man from his surrounding environment. The internal dose comes from those isotopes which are taken up by man and produce ionizing radiation inside the body. The food chain is the major vehicle by which this radioactivity is taken up by man except that there is considerable uncertainty regarding resuspension of plutonium. the sum of the internal and external doses. The total dose is It is our intention to REPOSITORY DOE this tor 4 Division coutection RS 326 Tome 4 N Crow JobH (320 BOX No. FOLDER a = - . RadwlogtealSucvey “ j
