Despite the Test Ban Treaty having been in effect for nearly three years, we again find our attention being directed towards the effects of radioactive fallout. In an article in this issue of Scientist and Citizen, Dr. Charles Mays discusses the probable exposure of residents of Utah to iodine 131 during the extensive 1951-55 test series. He points out that the data we have at our disposal, though admittedly subject to many objections, still forms the basis for recommending very strongly an extended investigation. Nearly three years ago, considerable interest and concern was aroused over this problem. Retrospective calculations indicated very strongly that many people, living in the areas of Utah and Nevada near to the weapons testing grounds, might have received much larger doses of iodine 131 radiation than had been realized. Evidence was presented at Congressional Hearings in 1963 and S/C was one of several journals which published articles and correspondence on this topic. Ina confused situation which has resulted from insufficient and poor data and poorer understanding, two points emerge as being central to the discussion: * The monitoring for iodine 131 was not carried out at all in the beginning and iodine 131 levels must be inferred from other radioactivity data, which are subject to dispute in their validity and relevance. * The "acceptable" or "permissible" levels of radiation to which people may be subjected have themselves been adjusted by the Federal Radiation Council, occasioning a protracted and completely unsatisfactory exchange with CNI as to the bases for making these changes. Perhaps by now readers may feel that this whole subject has been exhausted and that S/C should turn to more current problems. Unfortunately, we cannot. Dr. Mays again demonstrates, as the possible e¥fects of the DOE ARCHIVES 32
