What is the "unexposed group;" how many people? Some 200 unexposed people now living on Rongelap, including 75 children, are examined as part of the annual medical surveys for comparison purposes. 10. Q. How many children were in the heavily exposed group? There were twenty-five between 1 and 10 years of age at the time of the incident. ll. What was the estimated dose to the thyroid glands of the children? Their thyroids received doses possibly between 200 to 1400 rem largely from radioilodine. 12. What kind of shape are these people in now; and what other delayed effects, besides the nodules, have beenobserved? The general health and death rate of the exposed population on Rongelap have been about the same as for the comparison group. Other possible residual radiation effects noted in the 82 exposed Rongelapese were: slight retardation of statural growth and bone maturation in two boys exposed at less than 5 years of age; possibly a higher incidence of miscarriages in exposed women during the first four years; slower recovery of some of the peripheral blood elements, and non-malignant changes in some of the areas of previous beta radia- tion burns of the skin. No definite radiation effects on birth rate, aging, or leukemia have been noted. The numbers of people here are far too small for statistical analysis except in the ‘thyroid nodule case, - Je 36 aa 3g 306 F* q9$ )
