56 burden of 700 nanocuries of cesium 137 in an adult man corresponds to’ a whole body dose rate of ubout 125 millirems (0.125 rem) per year, ‘one-fourth of the limit generally used for controlling exposures of individual members of the public. This is roughly the average radiation dose to inhabitants of the U. S. from all natural sources of radiation inside and outside the body. However, perhaps a million or more in- habitants of the U. S. live in areas where levels of exposure to radiation from natural sources are higher than the national average by an additional 125 millirems per year or more. As far as we are aware, even persons well informed on the risks of radiation do not give appreciable weight to this exposure in considering 2 move of his family to or from an area inwhich the higher levels of radiation exist. We know of no reason for greater "worry" about the additional hazards associated with exposures of Eskimos to comparable doses of radiation from cesium 137. Question 11D _ | In your opinion, are these figures cause for concern? Would you be worried if your family or your own children carried Eskimo doses? Answer 11D 4 We are interested in the health and safety of all individuals, including the Eskimos in remote Anaktuvuk Pass. Our Battelle-Northwest Laboratory and the USPHS laboratories carefully monitor the levels of fallout radio~ activity in Eskimos to assure that doses do not exceed levels recommended by the FRC. This situation was recently reviewed by the FRC. The FRC Memorandum for the President on Radiation Protection Guidance for Federal |
