The result of radiologica: analyses oz Bikini samvcles ane RKoncgelat sam zles were comrarec sy inspection. The imcression from this subjective comparison is that the levele of radioactivity are closely similar for the two atolls. Certainly the range of values for comrarazie samcles overlap anc on the basis of single samples, sometimes Bikini has the highest values, sometimes Rongelap. To refine the comparison mucn further would require extensive information on specimen, species anc area variability. We trust that this information, which is typical of the data that we have, will be helpful to you. We expect that the Bikini-Eniwetok report mentioned in the second paragraph will be completed next month. Sincerely eeoett.. Bod. 27 Li. rn ALlyn k.
