retardation, yet the fact remains that no medication was given for this retardation for more than eleven years after the fallout. Despite the fact that the reports consistently mentioned the fact of unreliability of birth dates, these latter two cases were well documented, Furthermore, despite these unreliable birth dates, the reports kept mentioning the apparent retardation. Assuming that the administration of a hormonal agent would not be harmful to the children--even if it had no effect--it is difficult to understand why the doctors had to wait until the appearance of thyroid abnormalities in order to realize the value of administering Thyroxine to the growth-retarded youngsters. Another matter of concern to the Committee is the information in the threeyear report which indicates that: “Eight irradiated and nine unirradiated people were used in a study of immunological response to tetanus toxoid, The primary stimulus of tetanus toxoid had been given 2 1/2 months previously. Sera were obtained just prior to the second injection of toxoid and then six days later, Subsequently, tetanus toxin-antitoxin titrations of the sera were obtained for the two groups in mice by the method previously described." (p. 6) Leu In other words, these eight irradiated people were injected with a supposedly Sage amount of tetanus toxoid and later blood samples were taken just before a ad i) Leo second injection. The comparison of the blood’s reaction to the first and second injections was an indication of ttnether the ability of the blood to combat infections (such as tetanus) «us shown. What the Committee is especially concerned about is whether the people understood about the test, and whether or not they did, if there was any danger to any of the recipients. Assuming there was no people involved. Granted, such a study micht indicate a need for greater medical care of the people, should it be proven that their responses were poor, which would leave them open to serious illness in the future from what would normally be a simple infection, However, since it is often stated that the number of people involved is too small for statistical analysis in terms of other effects, it is curious | tee) heed ted further danger, the Committee questions just what benefit this study was to the | =—" 147
