In Utero Exposure

Question:   Which of the following statements is FALSE?

    A.  Leukemia is the most likely type of cancer to be induced by prenatal irradiation.
    B.  Doses of 4 rads absorbed by an embryo or fetus may result in an increased frequency of post-natal tumors, either benign or malignant.
    C.  There is evidence of an "abscopal effect” of radiation on the embryo and fetus. For example, radiotherapy for an oral tumor or a diagnostic dental series may induce an abortion in a pregnant woman even though the embryo absorbed no significant radiation.
    D.  The cohort of children receiving in utero radiation exposure from the atomic bombings did not demonstrate an increased incidence of childhood cancers, though an increased incidence in microcephaly was noted.
