35 Question LIA - Compared with Americans in the lower-8, many Eskimos carry very high _. body-burdens of unnatural, man-made radionuclides like strontium-90, © _ cestum-137 and iron-55. “ Question 11B “In fact, the mean average American body burden of cesium-137 is calculated -to be near 12 nanocuries now. For adult. Eskimos, it is 700. Question 11C In new York and New Jersey, the body burden of iron-55 is 13 nanocuries , but it is 1,100 nanocuries for fisheating Eskimos. Answer il1A, B, C Of the radionuclides to which Eskimos are exposed as a result of fallout ' from past tests of nuclear weapons, reported burdens of cesium 137 represent . the highest radiation doses.* While it is assumed that any small exposure to radiation represent some correspondingly small degree of hazerd to human | health, the radiation dose rate resulting from a body burden of 700 nanocuries -of cesium 137 in an adult is too small to be of great concern. It is also 50 small that one would expect that any measures that might be effective|in substantially reducing re the exposure would be expected to represent agreater : hazard to the well-being ef the Eskimo than does the radiation. Without attempt ing an exhaustive justification of these conclusions, .the following observations indicate that they are consistent with our evaluation of radiation risks to ourselves and to our families. A body *The levels of 7OO nanocuries is not . mean average for all Eskimos, as implied, but is chiuracteristic of levels in male adults in one or two localities. Levels in women and children are reported to be much lower.
