control patient gave a history of syphilis for which she had been treated twice. Interval histories were essentially negative. No deaths had occurred in the exposed population, and three apparently healthy infants had been born in the interim period. Their in utero ages at the time of exposure were approximately 3, 6, and 7 months. Three other pregnancies were noted during the present examinations, in one cf which conception had occurred at about the time of exposure and in the remaining two, 2 to 4 months after exposure.

Dermatological findings are reported in detail in Chap. 3. There appeared to be no significant difference in disease inci- dence between exposed and control populations, and no findings, with the exception of those reported in Chap. 3, could be ascribed to radiation effects. A measles epidemic, in progress in both populations during the examinations, had begun to decline in the control group but was still at its peak in the exposed group at the completion of this study. The time interval between the peak incidence of measles in the two populations was probably due to the relative isolation of the exposed group. Body weights of the exposed patients were compared with their weights in March, 1954. Although there were a few instances of significant weight loss in individuals, the over-all popu- 12
