Here's a paper on this topic.

Lloyd, R. D.; Tripp, D. A.; Kerber, R. A. Limits of fetal thyroid risk
from radioiodine exposure. Health Phys. 70:559-562; 1996.
Quotation from the Conclusion:
Concern for the possible consequences to the fetus of radioiodine
administration to its mother 9 d before conception motivated us to
search the data base for the Utah Fallout study (Stevens et al.)to
discover what effects had been documented among subjects exposed to
fallout radioiodine in utero. Not only was it found that no neoplasia
had occurred among this population, but there were no thyroid effects of
any kind in the persons with the highest thyroid doses (>0.5 Gy). Other,
non-neoplastic effects were about as common among subjects at the lowest
dose category (<0.01 Gy) as among those receiving 0.01-0.2 Gy,
indicating that any possible link with radiation exposure was extremely
weak. As an added bonus of this investigation, it was found that,
although the uncertainties were rather large, the fetal thyroid is
probably not much more sensitive to radiation-induced neoplastic change
than is the postnatal thyroid.
