by the universe square ration rule, emanating immediately from the bomb would be highly unlikely. I think the ill effects still persisting on these islands is not only due to soil contamination but is also due to entry of the radioactive elements with a longer half life into the food, where it has been biologically concentrated, and is eaten by the people. Whether the material that contains the radioisotopes is in one particular vegetable or several or whether it is in the fish ox birds, I simply do not know. One would think, that if the lagoon fish were involved, the food-chain exposure would involve only a few islands since I am told that lagoon fish usually stay in their lagoon. .If the large fish on the seaside that swim between atolls are involved and carry radioactivity in their flesh, these fish also being eaten by the islanders, one would expect a wider diffusion of the effects of the radioactivity, -- which is what has happened. There certainly would be diffusion by birds and actual transfer from one atoll to another of radioactive material in the excrement of birds flying between the attols. The wice diffusion of radioactive effects among the islands of the Marshalls, strongly suggests entry into the food chain with transportation between islands. This is as yet only @n opinion. Yet otherwise one must essume that the fallout just simply was so high, and has spread so far beyond that estimated by our finest nuclear scientists that distant islands and distant atolls in the Marshalls were involved, bringing about the radiation effects that I have described. To my knowledge, two cases of leukemia were found, one in a high government officer, and the other in a boy. There may be others. I am suspicious also that radiation plays a part here also because of the frequency of leukemia in the Nagasaki-Hiroshima survivors. I think that these three: the tumors of the thyroid
