None of these women had abnormal symptoms referable to pregnancy, and as far as could be determined, pregnancy continued in a normal fashion. In Group II, one woman was in the second trimester. No abnormality was detected. Fetal movements were unaffected in the individual in the third trimester. The hematologic changes of the pregnant womenare listed in Table 2.6. Two individuals in the first trimester had a marked depression of platelets but at no time was there any vaginal bleeding. So far, the exposure to radiation has not had a deleterious effect on pregnancy. At the 12 month reexaminationall of the above women had delivered. One baby was born dead; the others were normal. In the ease of the one still born, irradiation occurred to the mother either before conception or early in the first trimester. 2.8 Special Examination of Eyes Ct At 3 anp 6 Montus an ophthalmologist examined the eyes of all exposed individuals (10).
