be statistically significant, no definite causal relationship can be proven due to a number of variable factors, or the possibility of an unknown influence." A second area of concern by the Committee related to certain unproven assumptions and statements contrary to this hesitancy to make definite statements made in earlier reports, which apparently influenced assumptions and statements made in later reports. These general areas of concern will be elaborated upon more fully as appropriate, in the sections which immediately follow. AREAS OF PARTICULAR CONCERN Dose Estimates of Whole-Body Radiation from External Sources Since there was no RadSafe team with radiation monitoring instruments or radiation badges on Rongelap, Ailinginae, or Utirik at the time of the fallout, the exact amount of radioactivity to which the people on those islands were exposed cannot be calculated, and will never be known. result of three factors: This is generally the One, no one of these islands had a watch or clock which could have recorded the time which lapsed from the time the fallout began to when it appeared to have ended. so. Two, If someone did have a watch, they did not do there was great individual variation in exposures. For example, children, because of their greater activity and curiosity, may have been exposed to greater amounts of fallout than older persons. Conversely, this may be attenuated by the fact that children are wont to play in the ocean during hot days and may have inadvertently cleansed themselves of what larger amounts they picked up. Young, and middle-aged adults, however, may have received the largest doses because of following habitual patterns of daily activity which 1014694 *
