It was thought that an analysis of the tissues or organs could best be made rat ining the data of the active areas of Eniwetok and Bikini (see Table 3 and 3), but for comparative purposes the inactive areas have been added (see and Figure 3). In the case of the active areas the viscera shows the + amount of activity, followed by liver, bone, skin, and muscle in order asing amounts. Not enough samples of spleen or ovaries were taken to eliable information. «. There is some evidenceto indicate that natural radioactivity (such as ; absorbed in muscle tissue, and perhaps in other tissues, of fish caught ep and other comparatively inactive areas (see Table 4 and Figure 3). activity was revealed in all of the tissues sampled from these areas except case of liver tissues of fish from the inactive Eniwetok Islands. It is ected that the liver is a fairly good indicator of “extra-natural" radioactivity, | which might be worth further investigation. HALYSIS BY FEEDING HABITS.
