초록
The objective of this investigation was to evaluate of influence of gestational age at exposure on the prenatal effects of gamma-radiation. Pregnant ICR mice were exposed to single dose of 2.0 Gy gamma-radiation at gestation days from 2.5 to 15.5 days post-coitus. The animals were sacrificed on day 18 of gestation and the fetuses were examined for mortality, growth retardation, change in head size and any other morphological abnormalities. The only demonstrable effect of irradiation during the pre-implantation period was an increase in prenatal mortality. (omitted)
