including cancer, disturbances raGlation injury, and that the continuing injury is Cataracts, in vision probably due to and deformities of birth are a part of the in large part due to food-chain entry by long-lived radioactive elements. I strongly suspect that the leukemias were radiation induced. There are other areas about which I wonder and about which I yet have formed no firm opinion. am suspicious, I but as am told by the islanders that diabetes has become very comnon. When I spoke to the old people who remember the way the islands were before the nuclear testing, they all routinely deny that diabetes was a great problem for the inhabitants. Now as I speak to the Marshallese, I think that they have more diabetes than the Navajo Indians, and I had always thought the highest incidence was among the Navajos. Although Giabetes is exceedingly common among the Marshallese, I know of no direct radiation effect that causes diabetes. On the other hand, I do not know ell that is to be known about food chain radiation iniury and neither does anybody else. Our particular human experiences on radiation have been either with therapeutic radietion or the exterior type of radiation at Hiroshima and Nagasaki. Knowledge about food-chain radiation is scant and I am unable to Say whether the diabetes is related to the radiation or not. There are some sexual problezs among the males of the island, or among the females. A number of men from one atoll had told me that they develcped a failure of sexual interest after the explcesions, this persisting, and in several cases their families did not exdband after the bomb blasts. This also is likely rediation induced but I cannot say whether this is food-chain or whether this 1s perhaps external radiation coming from the soil, Since the testicles are in an expcesed position, particularly in people who so commenly sit on the ground or squat as do the people of the Marshall Islands. Immediate effects of the radiation occurred in some individuals who spoke to me, these changes consisting of hair loss, and burns of the skin. The burns of the skin occurred in those islanders in which there was a dusty, powdery fallout after the explosion called Bravo, which was effected by metereologic or inadvertence. There were MIs CALECUKN TION
